TYPEN HEATERELEMENTS HEATER

ELEMENT SELECTION - The “Full Load Amps.” listed in the tables are to be used for heater element selection. The rating of the relay in amperes at 40” C is 115% of the “Full Load Amps.” listed for the “Heater Type No.” Refer to the motor nameplate for the full load current, the service factor, and/or the motor classification by application and temperature rise. Use this motor nameplate information, the application rules, and the “Full Load Amps.” listed in the proper table (see Index on Page 2) to determine the “Heater Type No.”

OVERLOAD

RELAY CLASS DESIGNATIONS - Industry standards (NEMA Part ICS 2-222) designate an overload relay by a class number indicating the maximum time in seconds at which it will trip when carrying a current equal to 600 percent of its current rating.

Specific Applications may require Class 10 or Class 30 overload relays. Class 10 overload relays are often used with hermetic motors, submersible pumps, or motors with short locked rotor time capability. Class30 overload relaysshould be used with motors driving high inertia loads where additional accelerating time is needed. For application regarding Class 10 and 30 overload consult local Allen-Bradley office.

relays,

OF NOT LESS THAN 1.15, OR RISE NOT OVER 40°C.

- If the at the Controller than at the Motor full load current value shown on the motor nameplate is between the listed “Full Load Amps.“, select the “Heater Type No.” with the higher value. This will provide integral horsepower motors with protection between 115 and 125% of the nameplate full load currents.

2. Higher Temperature

3. Lower Temperature

- If the at the Controller than at the Motor full load current value shown on the motor nameplate is between the listed “Full Load Amps.“, select the “Heater Type No.” with the lower value. This will provide integral horsepower motors with protection between 105 and 115% of the nameplate full load currents.

A Class 30 overload relay will trip in 30 seconds or less at a current equal to 600 percent of its rating. Allen-Bradley standard overload relay protection using either Type N or W heater elements provide Class 20 operation and are recommended for General Application.

DUTY:

1. The Same Temperature at the Controller and the Motor - Select the “Heater Type No.” with the listed “Full Load Amps.” nearest the full load value shown on the motor nameplate. This will provide integral horsepower motors with protection between 110 and 120% of the nameplate full load currents.

A Class 10 overload relay will trip in 10 seconds or less at a current equal to 600 percent of its rating. A Class 20 overload relay will trip in 20 seconds or less at a current equal to 600 percent of its rating.

FOR CONTINUOUS

ALL OTHER MOTORS RATED FOR CONTINUOUS DUTY MOTORS WITH MARKED SERVICE FACTOR OF 1.01:

(INCLUDES

Select the “Heater Type No.” one rating smaller than determined by the rules in paragraphs 1, 2 and 3. This will provide protection at current levels 10% lower than indicated above.
