CJX4-KD Capacitor Switching Contactor

CJX4-KD range capacitor switching contactor is mainly used in AC 50Hz or 60Hz low voltage reactive power compensation equipment to switch on or off the capacitor, thus adjusting the power factor. It comes with rated insulation voltage up to 690V. Under AC-6b utilization category and rated working voltage of 400V, the equipment comes with rated working current of 87A. The contactor comes with surge current inhibit device, which helps effectively protect the capacitor and reduce operation over-voltage conditions.

The capacitor switching contactor is composed of one CSC1 series AC contactor, one group of change-over contact, and six current-limited resistive conductors. The change-over contact group is fixed on the top of the CSC1. On the both sides of CJX4-KD, auxiliary contacts F3-20d1 can be added to increase auxiliary contact quantity.
