Function and Usage
The NXCC series switching capacitor contactor (hereinafter referred to as the contactor) is mainly used in AC 50Hz (or 60Hz), rated working voltage up to 690V power lines, for the purpose of connecting or disconnecting low-voltage parallel capacitors in low-voltage reactive power compensation equipment. The contactor is equipped with a current surging suppression device, which can effectively reduce the closing surge current impact on the capacitor and suppress overvoltage during disconnection. It conforms to the standards: GB/T 14048.4, IEC/EN 60947-4-1.
