OWEL - DC indoor secant disconnector Application: OWEL disconnectors are isolating disconnectors designed for closing and opening unloaded circuits in industrial DC current networks. In open position, the disconnector creates visible and safe isolating clearance. It can be installed and operated in closed spaces, in the temperate of - 5°C up to 40°C. The device does not need spare parts during the time of 1000 cycles, but on special request the spare parts can be delivered to the customer. The replacement should be coordinated with the ELTOM company.
Advantages: ■■ simple and modular design ■■ reliability ■■ silver contacts ■■ easy to use ■■ good parameters
Technical characteristic: The disconnectors have secant construction. The basis is steel and it creates the sub-assembly with the shaft and the limiters of angle of rotation of the shaft. There are signal insulators mounted in the basis, on which there is the busbar. Interpolar insulation is the air gap. Normally, the drive is mounted on the right side of the disconnector. Disconnector can operate in vertical or horizontal position. OWEL II 3-31 and OWEL I 3-25 comply with the standard PN−93/E−06107.

OWPS - indoor rotary disconnector OWPS type disconnectors are devices used to connecting and disconnecting the electrical circuit without a load. Devices of this type are used in traction and in the industry. Mounted in a chamber, disconnector OWPS meets various roles such as: ■■ isolating the positive or negative end, or both assembly of transformer/ rectifier ■■ power supply isolation from the source of energy Thanks to its modular design, disconnector OWPS allows for a large number of different combinations and option, which allows it to carry out many functions.
Basic features: ■■ thermal current in open air from 1000 A up to 6300 A ■■ rated voltage: 1000 VDC, 1800 VDC i 3600 VDC ■■ high level of rated insulated voltage: 3000 VDC and 4800 VDC ■■ high rated short circuit strength ■■ connections covered with Ag ■■ self-cleaning contacts ■■ manual or motor operating ■■ auxiliary contacts: 1NO+1NC, 3NO+3NC, 6NO+6NC ■■ compliance with standards: PN-EN 50123-2:2013, PN-EN 50123-3:2003
Advantages: ■■ silver plated contacts ■■ silver plated busbars ■■ modular construction ■■ does not require spare parts ■■ reliability
