C45L earth leakage circuit breaker is used for the protection , against electrical leakage in the circuit of 50Hz or 60Hz, rated voltage single-phase 240V three phase 415V, rated current up to 60A. When somebody gets an electric shock or the residual current of the circuit exceeds the fixed value, it can cut off the power within the time of 0.1s automatically to protect the personal safety and preventing the equipment from the fault resulted by the Residual current.
