TXCPSL Control Protective Switch (leakage control and protective switching devices / kb0) in the basic control and protective switching devices on the basis of an increase of leakage protection, to prevent electric shock accident, to avoid leakage caused by fire accident, the control and protective switching devices can protect personal safety and equipment safety, the main switch is equipped with leakage test jump button, the user can press the button once every 1-2 months to check the leakage function is normal.

Rated leakage protection characteristics of TXCPSL control and protective switching devices

The rated residual current IL '> n is set according to customer requirements. Used to detect the equipment ground fault current, can provide additional protection to prevent damage to the equipment due to insulation damage and over-current protection function can not detect the continuity of the ground fault current caused by fire and other hazards. The trial jump button is only used to check the residual current trip function, not specifically for the disconnection operation.
