2

4 5 6 7 Through-the-Door Design

9 10 11 12 13

Cassette design: The breaker cassette supports the breaker in the cell, as well as on the movable extension rails when the breaker is placed into or removed from the cell. The extension rails allow the breaker to be drawn out without having to de-energize the entire switchgear lineup. Accessibility: When the door is open or removed, each breaker compartment provides front access to isolated, vertical wireways, primary disconnects, cell current transformers and other breaker compartment accessories for ease of field wiring and troubleshooting field connections.

14

Breaker inspection: When withdrawn on the rails, breaker is completely accessible for visual inspection; tilting is not necessary. The rails are permanent parts of every breaker compartment. Interference interlocks: Supplied on breakers and in compartments where the compartments are of the same physical size. Interference interlocks ensure an incorrect breaker cannot be inserted. Optional key interlock (switchgear mounted): This mechanism holds the breaker cell mechanically trip-free to prevent electrical or manual closing. Breaker can be stored in compartment, and completely removed for maintenance or for use as a spare without disturbing the interlock. Modification of the breaker is not required. Optional mechanical interlock: Available between adjacent breakers to ensure the proper sequence of operation between two circuit breakers.

15 16

Bus Features Buses and connections: Vertical and cross bus ratings in Magnum DS switchgear are based on a UL and ANSI standard temperature rise of 65 °C above a maximum ambient air temperature of 40 °C.

17 18 19

Closing spring automatic discharge: Mechanical interlocking automatically discharges the closing springs when the breaker is removed from its compartment. Optional safety shutters: Positive acting safety shutters that isolate the breaker connections to the main bus when the breaker is withdrawn from the cell is an option offered for additional safety beyond our standard design. They reduce the potential of accidental contact with live bus. Insulating covers (“boots”) are furnished on live main stationary disconnecting contacts in compartments equipped for future breakers.

Bus ampacities: Vertical and main bus ratings in Magnum DS are 2000, 3200, 4000 and 5000 A. In addition, a 6000, 8000 and 10,000 A main bus rating is available. Vertical section bus is sized per main cross bus maximum rating or by ANSI C37.20.1 to a maximum of 5000 A. Bus bracing: Standard bracing is 100,000 A. Unique vertical bus configuration provides an optional industry-leading short-circuit withstand rating of 200,000 A. The “U” shaped bar is the heart of the Magnum DS vertical bus. This configuration provides a much higher mechanical strength. To further demonstrate the strength and rigidity of this bus system, it has been verified through testing to withstand 85,000 A shortcircuit for a full 60 cycles. Silver and tin plating: Bolted, silverplated copper bus is standard. The plating is over the entire length of the bar, not just at the joints. Optional tin-plated copper bus is available. Bus joints: All joints are bolted and secured with Belleville-type spring washers for maximum joint integrity. These washers reduce the potential of joint hardware loosening during the change of joint temperature associated with variations of the loads. Optional maintenance-free hardware is also available. Full neutral: For four-wire applications, the neutral bus is rated 100% of main bus rating as standard. Neutral ratings up to a maximum of 10,000 A are available as an option. Additionally, four-pole breakers can be used in conjunction with four-wire systems. Ground: A ground bus is furnished the full length of the switchgear assembly and is fitted with terminals for purchaser’s connections. Glass reinforced polyester and Ultramid® standoff insulation system: Glass reinforced polyester has been used on both low and medium voltage switchgear for decades. By combining this industry proven material with Ultramid insulation, a total system providing exceptional mechanical and dielectric withstand strength, as well as high resistance to heat, flame and moisture, is produced. Substantial testing to demonstrate accelerated effects of heating and cooling on the mechanical and dielectric properties of this system prove it to provide superior performance for decades of trouble-free operation.

General Description Optional epoxy bus coating: For applications requiring additional bus protection in harsh environments, Magnum DS switchgear is designed for the addition of optional conductor insulation covering, in addition to providing full UL air clearance without insulation. This material is applied during the assembly of the bus, and covers all vertical and horizontal phase bus bars. Removable boots provide access to section-to-section bus joints for inspection and maintenance purposes. This insulation is not available for vertical sections containing Series NRX® breakers.

Optional Insulated Bus

Barriers: Optional grounded metal barriers isolate the main bus and connections from the cable compartment providing added safety to the workers while reducing the potential of objects falling into the bus compartment. In addition, vertical barriers between cable sections can be added to reduce potential hazards. Barriers are removable to give access to the bus compartment for inspection and maintenance. Barriers can be either solid metal or vented for ease of infrared scanning.

Wiring Features Cable compartment: The cable compartment gives ample room for terminating the power cables. Removable top roof sheets allow for easy conduit hub installation. The floor of the cable compartment is open to allow cable entry from underground duct banks. Optional floor plates are available. Pow-R-Way®

busIn addition to cable, way and nonsegregated bus duct can be terminated in the compartment. Lug pad: The lugs are located on the breaker run-backs to accommodate lug orientations at a 45° angle to reduce the bending radius of the cable needed for making the connections, thus reducing installation and maintenance time. Mechanical setscrew type lugs are standard. Optional NEMA two-hole compression lugs are available as an option. Control wireway: An isolated vertical wireway is provided for routing of factory and field wiring in each switchgear section. Breaker secondary terminal blocks are mounted as standard above each circuit breaker. The terminal blocks are rated 30 A, and will accept bare wire, ring or spade terminals for wire size ranges of #22–#10. Extruded loops are punched in side sheets of the vertical wireway to allow securing of customer control wiring without the use of adhesive wire anchors. Control circuits may be wired in all cells without removing the circuit breaker. In addition, power circuits may be connected in the rear of the switchgear at the same time control circuits are being wired in the front of the switchgear. Control wire: Standard wire is Type SIS insulated stranded copper, extra flexible No. 14 AWG minimum. Type VW-1 wire is available.

Control wire marking: Each wire is imprinted with ink cured under ultraviolet light for durability and for easy identification by the user. The enhanced solvent resistance and durability of the aerospace grade UV cure ink has been tested for severe environments. The imprinting is made every 3.00 inches (76.2 mm) along the length of the wire to make field troubleshooting easier. The point of origin, wire designation and point of destination are imprinted in the following format: . Each device has a uniquely designated zone. “” indicates the direction of the wire destination. As an option, wire name marking can be made using sleeve type or heat shrink sleeve type.

Arc-resistant low voltage switchgear is a new development in the Magnum DS line that protects operating and maintenance personnel from dangerous arcing faults by channeling the arc energy out the top of the switchgear. Arc faults, caused by human error or insulation failure, can generate thermal energy as high as 35,000 °F and a blast equivalent to 20.7 lb of TNT. While arc-resistant gear does not prevent these arcs from occurring, it does safely redirect and contain arcs that do occur, regardless of the originating location of the arc. ArcGard Magnum DS switchgear has been tested in all three compartments for a full 0.5 seconds, passing ANSI Type 2 and Type 2B standards at 100 kA at 508 V and 85 kA at 635 V. Indoor rear access construction and indoor front access construction are available as arc-resistant Type 2B.

Type 2B: Switchgear with Type 2 accessibility plus arc-resistant in front of the instrument/control compartment with the instrument/ control compartment door opened. (Type 2B incorporates Type 2.)

Normal Operating Conditions Eaton arc-resistant switchgear is Type 2B. Instrument/control compartment door and breaker secondary door can be open and maintain Type 2B protection. Arc-resistant features are intended to provide an additional degree of protection to the personnel performing normal operating duties in close proximity to the equipment while the equipment is operating under normal conditions. The normal operating conditions for proper application of arc-resistant switchgear designs are as follows: ■ ■ ■

Magnum DS Power Circuit Breakers Eaton’s Type MDS power circuit breakers constitute a complete, modern and rugged line of low voltage power circuit breakers using Eaton’s DE-ION® principle of arc extinction. The breaker family is distinguished by its similarity of appearance and operation frame to frame. All frame sizes are either manually or electrically operated. Refer to Tab 26 for detailed information on Magnum DS low voltage power circuit breakers.

Stored-Energy Mechanism

ii

Release of the stored energy is accomplished by manually depressing a button on the front of the breaker or electrically energizing a releasing solenoid.

Breaker Features

Magnum MDSX Current Limiting Power Circuit Breakers have fast opening contacts to provide interrupting ratings up to 200 kA at 480 Vac without fuses.

Four Physical Frame Sizes Narrow, standard, double narrow and double to promote breaker application in compact modular enclosures and to improve enclosure density.

Arc Chute There are three basic means of extinguishing an arc: lengthening the arc path; cooling by gas blast or contraction; deionizing or physically removing the conduction particles from the arc path.

Contacts Magnum DS has silver tungsten moving contacts and silver graphite stationary contacts. The contacts provide a long-wearing, low-resistance joint. The contacts are protected from arcing damage even after repeated interruptions by the “heel-toe” action, which causes the integral arcing contacts to mate before the main contacts part. The arcing contacts then part last, striking the arc away from the main contacts.

i

A cam-type closing mechanism closes the breaker. It receives its energy from a spring that can be charged by a manual handle on the front of the breaker or by a universal electric motor.

Magnum DS Low Voltage Power Circuit Breakers have high withstand ratings from 42 to100 kA to provide for maximum system coordination and selectivity.

The DE-ION principle is incorporated in all Magnum DS circuit breakers. This makes possible faster arc extinction for a given contact travel, ensures positive interruption and minimum contact burning.

Levering Mechanism The worm gear levering mechanism is self-contained on the breaker drawout element and engages slots in the breaker compartment. A standard 3/8-inch (10 mm) drive set is used to lever the breaker between the connected, test and disconnected positions.

The main contacts are of the butt type and are composed of multiple fingers to give many points of contact without alignment being critical.

Magnum MDSL Current Limiting Power Circuit Breakers have integral current limiters to provide interrupting ratings of 200 kA at 600 Vac.

Mechanical interlocking is arranged so that levering cannot be accomplished unless the breaker is in the opened position.

Protection During Levering Operation When levering the breaker between the connected, test and disconnected positions, the operator is protected from contact with live parts by the breaker door. True two-step stored energy closing: Refers to the sequence required to charge and close the breaker. 1. The breaker closing springs are charged either through the manual-charging handle or by the optional charging motor. The breaker is mechanically interlocked to prevent closing of the breaker until the closing springs are fully charged. 2. With the closing springs fully charged, the breaker can then be closed by pressing the manual close pushbutton on the breaker, or by the optional spring release coil through a remote electrical signal. This means that the energy required to open the breaker is always restored following a closing operation. “Stored energy” is energy held in waiting, ready to open or close the breaker within five cycles or less. The unique cam and spring design provides necessary energy for a single close-open sequence as well as the energy for multiple charge-close operations such as this possible sequence: charge-close-rechargeopen-close-open.

Provisions for padlocking: All breakers include provision for padlocking open to prevent electrical or manual closing. This padlocking can secure the breaker in the connected, test or disconnected position by preventing levering of the breaker.

Optional Breaker Accessories ■

■

Ease of inspection and maintenance: Magnum DS breakers are designed for maximum accessibility and the utmost ease of inspection and maintenance. Manually operated breakers: Manually operated breakers are equipped with a manual charging handle to charge the closing springs. Manual closing and tripping pushbuttons are used to operate the breaker. Remote closing and tripping can be accomplished by installing optional electric spring release and shunt trip coils (see Tables 20.1-10 and 20.1-11 for available control voltages, currents and motor-operated spring charging times). The breaker closing springs must be charged manually, then remote closing and tripping signals can be sent to the breaker. Electrically operated breakers: Electrically operated breakers are equipped with a spring charging motor and electrically operated spring release and shunt trip coils (see Tables 20.1-10 and 20.1-11 for available control voltages, currents and motor-operated spring charging times). The breaker manual charging handle can be used to charge the closing springs when power is not available to the charging motor.

October 2015 Sheet 20 013

General Description—Electronic Trip Units

Magnum DS Switchgear— Trip Units Digitrip™ RMS trip unit. Eaton’s Digitrip RMS trip units feature a dependent curve that is depicted in the nameplate by a blue shaded area of the trip curve. The dependent curve affords better protection flexibility. Additionally, all of the trip units have, as standard, thermal memory, 50/60 Hz operation and thermal self-protection at 90 °C. Digitrip RMS integral microprocessorbased breaker overcurrent trip systems: Provide maximum reliability with true rms sensing as standard, gives excellent repeatability and requires minimum maintenance. No external control source is required for its protective functions.

Trip functions: Magnum DS trip units provide the maximum in flexibility and are available in the following configurations: LSI, LSIG, LSIA (ground fault alarm only). In each case, either the short delay or instantaneous (not both) functions may be defeated. This reduces the need for spare breaker inventories and provides maximum usage of interchangeable breakers. Digitrip RMS 520: Enables the user as many as nine phase and ground current protection settings for maximum flexibility in trip-curve shaping and multi-unit coordination, and adds zone selective interlocking. Digitrip RMS 520M: Adds phase, neutral and ground current metering with a four-character LCD display window with 2% current metering accuracy and type LSIA alarm when ground fault settings are exceeded. Digitrip RMS 520MC: Adds communication of trip values and breaker status (open, close and tripped). Adds Arcflash Reduction Maintenance System (ARMS).

Digitrip 1150+

Digitrip RMS 1150+: Provides programmability for more sophisticated distribution systems. Adds Arcflash Reduction Maintenance System (ARMS).

■

Increased protection and coordination capabilities ■ Systems monitoring information including power factor, voltage current, harmonic distortion values, and waveform capture with a three-line, (eight characters per line) LED display ■ Two programmable contacts for customer use ■ Time stamping of trip events for improved troubleshooting and diagnostics ■ Accuracy of 1% on metered values and 2% on energy and power ■ Systems diagnostic information ■ Web enabled or PowerNet™ communications ■ Breaker health menu ■ Additional protection functions: ❑ Undervoltage/overvoltage ❑ Underfrequency/overfrequency ❑ Voltage unbalance ❑ Reverse power Zone selective interlocking: The Digitrip RMS zone selective interlocking (ZSI) capability provides positive system coordination without time delays. ZSI allows the breaker closest to the fault to trip without any preset time delay. The breaker closest to the fault trips first, while the remainder of the distribution system remains online, thus avoiding unnecessary and costly downtime. The use of ZSI in Spot Network Systems is not recommended by Eaton. See the discussion in section 18 for the technical reasons why Eaton does not recommend ZSI in Spot Network Systems.

Arcflash Reduction Maintenance System The Arcflash Reduction Maintenance System Maintenance Mode function of the Digitrip 520MC and 1150+ can reduce arc flash incident energy that is generated on a fault condition. Eaton’s Arcflash Reduction Maintenance System employs a separate, dedicated analog trip circuit that eliminates microprocessor latencies, resulting in clearing times that are faster than standard instantaneous tripping. This provides superior arc flash reduction to competing systems that simply lower the standard instantaneous pickup set point. There are three ways to arm the Maintenance Mode Arc Flash Reduction setting. One method is locally at the trip unit front panel. For the 520MC, the 2-position switch in the Maintenance Mode section of the trip unit is used. Turning the switch to the ON position will arm the setting. For the 1150+, the local front keypad is used to enable the Maintenance Mode setting. The setting is located in the SYSTEM submenu of programmable settings (PGM SET).

For the second method of arming the Maintenance Mode function, a remote switch wired through the breaker secondary contacts can remotely arm the Maintenance Mode setting. A high-quality gold-plated or palladium contact is required in this application. A third method to arm the maintenance setting is via a communication device. This can be accomplished through a Power Xpert® Gateway. A BIM (Breaker Interface Module), Power Xpert software or PowerNet system is another communication method to arm the setting. For Magnum DS breakers, the Arcflash Reduction Maintenance System setting has five unique settings (2.5, 4.0, 6.0, 8.0, 10.0 x In). To adjust this setting, a rotary switch on the trip unit face is provided for the 520MC while the 1150+ trip unit uses its local keypad. For the Series NRX breakers, the Arcflash Reduction Maintenance System setting has a constant setting of 5000 A. For all three arming methods, the 520MC provides a blue LED to confirm the Maintenance Mode function is on. In addition, there is also a normally open breaker contact that allows the user to wire in an external stacklight or annunciator for remote indication. For the 1150+, the message “Maintenance Mode Enabled” will be shown on its LED display. The 1150+ also has an alarm relay that can be programmed to track the Maintenance Mode state.

The Maintenance Mode function will provide fast tripping even when the regular Instantaneous is set to OFF. The Instantaneous LED position is also used to indicate a trip initiated by the Maintenance Mode setting. The 520MC LCD display, if powered, will indicate with four dashes while the 1150+ will display the message “Maintenance Mode Trip.”

Arcflash Reduction Maintenance System

The Arcflash Reduction Maintenance System can be wired out to a separate lockable switch/light combination mounted on the switchgear for ease of operation. Additionally, the switch can be wired out to a remote station for operation outside the arc flash boundary of the switchgear, and the alarm can be wired to an optional beacon or audible device.

Series NRX—General Description

Series NRX

Series NRX Breakers Have a Compact But Powerful Size to Provide Interrupting Ratings up to 65 kA at 480 Vac

General Description The Series NRX provides the performance of a power circuit breaker— 65 kA interrupting at 480 Vac—in the compact size of a molded case breaker. It offers the protection and features of a power circuit breaker, along with increased flexibility at a portion of the size. All frame sizes are either electrically or mechanically operated. The Series NRX is tested to 20,000 mechanical operations and 10,000 electrical operations—significantly higher than industry standards, such as UL and IEC, require or the capabilities of equivalent products on the market. Thus, your maintenance personnel can do what needs to be done, instead of spending valuable time inspecting and maintaining the breakers in the system.

In switchgear, it’s important that the breaker be easily accessible during scheduled equipment maintenance. The design of the breaker and cassette enables full use of the breaker handle and cassette rails with a gloved hand, allowing electricians to remain in the appropriate PPE protective gear. The breaker’s ergonomic design also maximizes functionality. Individual Series NRX breaker door will open in a “saloon” or “barn” type of arrangement so that personnel can access one of the side-by-side breakers without having to interact with the other. The breaker’s handle allows the operator to easily apply leverage across seven complete strokes (with an average of only 21 lb of force) charging the breaker quickly and easily, and making it easier to cycle when needed during commissioning or scheduled maintenance. Series NRX breakers use a true two-step stored energy mechanism similar to Magnum DS breakers. The reduced weight of the Series NRX makes it easier to handle during startup and scheduled inspection. A threepole, fully populated drawout breaker weighs only 54 lb/24 kg. The Series NRX enables twice as many feeder breakers in a standard structure for a reduction in overall assembly size of up to 50%. The small size, 10.00 inches (254.0 mm) wide by 10.70 inches (271.8 mm) deep by 14.20 inches (360.7 mm) high, of the Series NRX allows for much higher densities of power circuit breakers in a structure—up to eight breakers in a 24.00-inch (609.6 mm) wide structure—and a 2.50-inch (63.5 mm) customer wireway. This means that two Series NRX breakers can be mounted side-by-side in the same space typically used for one Magnum DS breaker. The Series NRX breakers can also be mixed and matched with Magnum DS breakers, increasing layout flexibility and providing the ability to stack feeder breakers around larger main and tie breakers. See layout guide for more details.

All optional Magnum DS breaker attachments and accessories are also available for the Series NRX breakers. Series NRX accessories can be quickly installed at the job site, without any special tools. Each breaker comes standard with an accessory tray; the needed accessories simply plug and lock into the tray. The Series NRX uses one CT for the breaker frame. This eliminates the need to match CTs and rating plugs to change the continuous current rating of the breaker. For example, changing from 1200 to 800 A on previous breaker designs required changing CT from 1200 to 800 A and changing the rating plug from 1200 to 800 A. The Series NRX breaker simplifies this process by only requiring changing the 1200 A rating plug to 800 A. This is accomplished through the Series NRX’s Rogowski air core CT. The Rogowski coil does not saturate like a traditional ferrous core CT, allowing the CT to be used across a broad current range with greater accuracy. One sensor accommodates 200–1200 A range. A full range of trip units, ranging from basic protection (LSI or LSIG) to metering, system diagnostics, protective relay functions and communications, complement the breaker offering. Two of the trip unit models, the Digitrip 520M and 1150, include (optional) Eaton’s Arcflash Reduction Maintenance System, built to reduce arc flash energy on a downstream unit during system maintenance. Zone selective interlocking is also available. When communication capability is required, the Series NRX breaker has cassette-mounted modules, eliminating the need for readdressing replacement breakers. These DIN rail mounted modules save space and time during installation and are available for field mounting capability. Modules for Modus and Eaton’s INCOM system are available with future releases for PROFIBUS and Ethernet compatible with Eaton’s Power Xpert Architecture protocols. Refer to Tab 26 for more detailed information on Series NRX breakers.

General Description

Local Subnetwork Display

❑

The IQ 100 meter family provides capabilities you would not normally expect in affordable, compact meters, such as fast sampling rate and accurate metering for a full range of power attributes. Providing the first line of defense against costly power problems, Eaton’s IQ 100 series electronic power meters can perform the work of an entire wall of legacy metering equipment using today’s technology.

See Tab 4.

When space is at a premium, yet you need ANSI C12.20 accuracy, the IQ 100 series fits the bill. These meters are ideal for electrical equipment assemblies, machine control panels, such as panelboard and switchboard mains and feeders, low voltage metalenclosed switchgear feeders and motor control centers. Requiring far less space than other meters with similar functionality, IQ 100 series meters fit into a standard ANSI or IEC cutout on a panelboard or other electrical equipment, and therefore fit easily into retrofit applications.

C-HRG Free-Standing NEMA 1 Unit

Where continuity of service is a high priority, high-resistance grounding can add the safety of a grounded system while minimizing the risk of service interruptions due to grounds. The concept is a simple one: provide a path for ground current via a resistance that limits the current magnitude, and monitor to determine when an abnormal condition exists. This provides for maximum continuity of service, because no tripping occurs for the resistance limited ground fault. HRG can be installed as stand-alone equipment (as shown in photo) or can be integrated into Magnum DS low voltage switchgear; however, the use of HRG is restricted to systems that do not have single-phase or phase to neutral loads.

Notes: Full Load of Section or Breaker comes from the frame or bus ratings of the product. Actual Amperes is a loading profile over all the devices for the operating scenario of interest. Rating Factor is a value that appropriately “weights” the nominal losses at full load to the actual losses for the actual loading value. The formula is Rating Factor = (Actual Loading/Full Load Rating) x (Actual Loading/Full Load Rating). The Rating Factor is applied (multiplied) by the Full Load Loss Watts to get Net Watts for each item. See Table 20.1-7 for Nominal heat loss data for devices and sections.

Interrupting ratings shown based on breaker equipped with integral Digitrip RMS trip unit. Interruption ratings for non-automatic breakers are equal to the published short-time withstand rating. These interruption ratings are based on the standard duty cycle consisting of an open operation, a 15-second interval and a close-open operation, in succession, with delayed tripping in case of short-delay devices. The standard duty cycle for short-time ratings consists of maintaining the rated current for two periods of 1/2 second each, with a 15-second interval of zero current between the two periods. Magnum MDSL current limiting power circuit breaker with integral current limiters. Current limiter selected determines short-time and fixed instantaneous trip rating. Maximum voltage rating is 600 Vac. Magnum MDSX current limiting power circuit breaker with fast opening contacts. Series NRX uses the same sensors for all trip settings. No changes to sensors required.

ANSI Meter Accuracy Classification

The narrow-band characteristic curve allows close coordination with Digitrip RMS tripping devices. Repeatability is within 2%.

Breaker Frame Rating 800, 1600, 2000

The maximum breaker current rating for any breaker frame size is determined by the rating of the sensor used. The breaker current rating for any frame size can be changed by simply changing the sensors and associated rating plug, which are easily removed from the breaker drawout element. The wide range of long-delay pickup makes one set of sensors more flexible on a wider range of loads. The Digitrip RMS itself need not be changed when the associated sensors and rating plugs are changed.

3200

Eaton’s Digitrip RMS can be supplied in various combinations of four independent, adjustable, overcurrent protection functions:

Long delay (L) Instantaneous (I) ■ Short delay (S) ■ Ground (G) ■ Ground alarm only (A) Every Eaton Magnum DS trip unit comes standard with LSI characteristics. Optional ground (G) or ground alarm (A) may also be provided. These trip units also provide the ability to defeat instantaneous to provide LS protection only. In addition, short delay protection may be set to the maximum instantaneous level, effectively disabling short delay protection. Under no condition is it possible to set the trip unit beyond the capabilities of the circuit breaker.

Current transformers with meter accuracy classifications at higher burdens and/or suitable for relaying are also available. They will be mounted in the rear cable connection compartment.

A transition section is required when close-coupling to an Eaton sourced liquid filled transformer. A transition section is required when close coupling to non-Eaton sourced transformers. A transition section is required when close coupling to other distribution equipment. A maximum of two 3200 A breakers are permitted per 22.00-inch (558.8 mm) width of switchgear, one of which must be a main or tie. A 3200 A frame breaker cannot be mounted in the same enclosure with a 4000 A main or tie. For a 3200 A frame breaker mounted in the same enclosure with a 5000 A main or tie, contact Eaton. Contact Eaton for placement of 2000 A frame breaker in this compartment. A maximum of three 2000 A breakers are 22.00-inch (558.8 mm) width of switchgear. If three are required, positions B, C and D must be used. Any 22.00-inch (558.8 mm) wide compartment can be a blank or instrument compartment.

Notes: Breaker and cell utilization should keep load amperes below rating of MAIN due to vertical bus limitations. Cable used in the conduit areas are limited to 75 °C ampacity values per the NEC for ampacity calculations. Any cell not used as a feeder breaker may be a blank, or a feeder breaker provision for future breakers, or SPD surge.

24 structure feeders are limited to Series NRX frame, 800 A maximum. Main and Tie are Magnum DS frames, limited to frame ampacities shown. Feeder breaker may be Magnum DS type, limited to the ampacities shown.

Notes: Breaker and cell utilization should keep load amperes below rating of MAIN due to vertical bus limitations. Cable used in the conduit areas are limited to 75 °C ampacity values per the NEC for ampacity calculations. Any cell not used as a fee der breaker may be a blank, or a feeder breaker provision for future breakers, or SPD surge. Cable compartment must be at least as wide as the breaker compartment. Cable sections must be on the right-hand side of the breaker sections when facing the front.

Application

Table 20.1-27. Altitude Derating Factors Altitude

Standards Magnum DS circuit breakers meet or exceed all applicable requirements of ANSI Standards C37.13, C37.17, C37.50 and CSA.

System Voltage and Frequency Magnum DS breakers are designed for operation on AC systems only, 60 Hz or 50 Hz, 635 V maximum.

Continuous Current Ratings Unlike transformers, generators and motors, circuit breakers are maximumrated devices and have no built-in temporary overload current ratings. Consequently, it is vital that each application take into consideration the maximum anticipated current demand, initial and future, including temporary overloads. The continuous rating of any Magnum DS breaker is limited to the sensor rating, or the frame size current rating, whichever is the lesser. For instance, an MDS-616 1600 A frame breaker with 800 A sensors has a maximum continuous rating of 800 A, but the same breaker with 1600 A sensors is limited to 1600 A maximum. All current ratings are based on a maximum ambient air temperature of 40 °C (104 °F).

kAIC rating is required. Per IEEE sanctioned methodology, the calculated short circuit current at the point of interest is increased by the Table 20.1-27 multiplying factors (MF) to yield an “apparent value of short circuit current,” which is then compared to the published breaker ratings. Only breakers having published ratings higher than the “apparent fault current” can be safely applied. For example, if unfused air power breakers rated 65 kAIC were being considered within a 480/277 Vac distribution system where the X/R at the point of breaker application is 14.25 and the calculated fault current was determined to be 60 kA, the determination of the suitability of these breakers yields:

All low voltage air power circuit breakers are tested per the ANSI Standard C37.1 for a system X/R ratio of 6.6 maximum. It is common within low voltage systems to experience power factor and X/R values outside the range of the standard values, and thus a means to evaluate published product ratings is necessary.

Apparent Fault Current = 60 kA x MF

= 66.72 kA and therefore because 66.72 kA exceeds the 65 kAIC rating, the breakers are not adequate and higher rated kAIC breakers would need to be applied.

Unusual Environmental and Operating Conditions

Special attention should be given to applications subject to the following conditions:

1

1. Damaging or hazardous fumes, vapors, etc.

2

2. Excessive or abrasive dust.

3 4 5 6 7 8

For such conditions, it is generally recommended that the switchgear be installed in a clean, dry room, with filtered and/or pressurized clean air. This method permits the use of standard indoor switchgear and avoids the derating effect of non-ventilated enclosures. 3. Salt spray, excessive moisture, dripping, etc. Drip shields in equipment rooms and space heaters in indoor weatherproof enclosures, may be indicated, depending upon the severity of the conditions.

4. Excessively high or low ambient temperatures. For ambient temperatures exceeding 40 °C, and based on a standard temperature rise of 65 °C, the continuous current ratings of breaker frame sizes, and also buses, current transformers, etc., will be subject to a derating factor calculated from the following formula: 105º Total—Special Ambient, ºC ----------------------------------------------------------------------------------------105º Total—40 ºC Standard Ambient Circuit breakers are not adversely affected by very low outdoor ambient temperatures, particularly when energized and carrying load currents. The standard space heaters in weatherproof switchgear will raise the temperature slightly and prevent condensation. Electrical components such as relays and instruments, however, must be applied within the manufacturer’s specified limits. 5. Exposure to seismic shock.

9 10 11 12 13 14

Magnum DS assemblies and breakers have been certified for applications through International Building Code 2009 (IBC) and California Building Code 2010 (CBC). Assembly modifications may be required, so such conditions must be specified. 6. Abnormally high frequency of operation. In line with above, a lesser number of operations between servicing, and more frequent replacement of parts, may be indicated.
