Audited Supplier GSC1-kd series of capacitor changeover contactor is used in the circuit of AC 50Hz(or 60Hz), rated insulation voltage up to 690V, rated current is from 18A up to 87A for AC-6b at rated voltage of 400V to 440V for the purpose of closing or breaking capacitor bank, which is used for low voltage reactive power compensation, and then adjusting power factor value of power system. Contactor with inrush current suppression device can effectively reduce the impact on capacitor bank from switching inrush current and reduce operation over-voltage.
