CJ19(16) series switching capacitor contactor overview

CJ19(16)-25, 32, 43, 63, 85, 95 switching capacitor contactor, dedicated to switching low-voltage shunt capacitors, widely used in AC 50Hz, voltage to 380V reactive power compensation equipment, contactor with suppression of inrush current device, It can effectively reduce the impact of the closing inrush current on the electric vessel and reduce the operating overvoltage at the moment of disconnection. It can replace the original switching installation composed of one contactor and three current-limiting reactors. It has small volume, light weight, strong on-off ability and easy installation.

Use and maintenance

■ The inlet line and outlet line of the contactor must be connected reliably, so as not to cause inter-phase flaring due to fire during the power-on time, damaging the contactor and equipment.

■ When the capacitor is closed, if the surge current is too large, exceeding the inhibition ability of the contactor, the resistance may be burned out, at this time, the electrical resistance can be replaced and continue to use.

■ The insulation voltage of the electrical appliance used in the discharge device in the reactive power compensation equipment should be greater than 2Ue to avoid damage to the contactor due to the fault of the discharge device.
