Application

The DZ47LE residual current operated  circuit breaker is applicable to the circuit with an alternating current of 50Hz, rated-voltage single pole and two lines/two poles 230V, three poles/three poles and four lines/four poles 400V, and a rated current 63~125A; when the human body gets an electric shock or the networkleakcurrent exceeds the specified value, the residual current operated  circuit breaker can rapidly cut off the power supply in trouble within a very short time for the safety of the human body and the powered equipment. With the function of overload and short circuit protection,  the residual current operated  circuit breaker can be used to protect the circuit or motor from being damaged by overload and short circuit, and can also be used for not–frequent operational transformation in the circuit under normal condition.The product meets the standards of GB14048.2 and IEC60947-2.
