CJ19 Switching Capacitor Contactor
Product Classification：Capacitor Switching Switch
Company Brands：Yadulan Electric
Product Introduction：CJ19 (16) -25, 32, 43, 63, 85, 95 switching capacitor contactors, specifically designed for switching low-voltage parallel capacitors, are widely used in reactive power compensation equipment with AC 50Hz and voltage up to 380V. The contactors are equipped with surge suppression devices, which can effectively reduce the impact of closing surge on capacitors and reduce the operating overvoltage at the moment of disconnection. They can replace the switching device composed of one contactor and three current limiting reactors, and have a small volume Lightweight, strong breaking capacity, and convenient installation.
