WGB013L earh leakage circuit breaker is used for the protection, against electrical leakage in the circuit of AC 50/60Hz, rated voltage of single pole up to 240V, 3 pase 415V, rated current up to 63A. When somebody gets an electric shock or the residual current of the circuit exceeds the fixed value, the ELCB can cut off the power within the time of 0.1s automatically protecting the personal safety and preventing the equipment from the fault resulted from the residual current. With this function, the ELCB can protect the circuit against overload and short circuit or can be used for the unfrequent switch over of the circuit under normal condition. It conforms to IEC60989 & IEC60755.
