The AC contactors HCJ19-43 are specially designed electrical devices for commutation of three phase capactors used of power correction.They are alternating current contactor LT1 Dxx with mounted a group for peak current lowering from the transitional process of the capaitor’s switching on/off.This group is a combination of current limiting resistors,switched on in the beginning of the transitional process(switching on/off capacitor group).The contactors are suitable for capacitors with rate up to 50 kVAr.
Functions
■ switching on/off of capacitors for reactive power compensation
■ making of systems for compensation of the energy reactive component
■ lowering of the peak transitional currents at switching on/off of the capacitor
■ remarkable with high reliability of current characterisitcs
■ reliable separation of power contacts
■ secured part of the contactor against consumer contact
