Scope of Application

DZ47LE-63 Residual Current Circuit Breaker (hereinafter referred to as ELCB breaker) is used for the line of AC 50Hz, rated voltage of 400V, rated current of 50A, as leakage and overload protection for home and similar purposes, to prevent the fire or the personnel casualty caused by circuit leakage or electric shock, also to provide over-voltage protection for excessively rised voltage caused by the grid fault.
This ELCB breaker complies with standards of IEC61009-1: 1996, GB16917.1 "Residual current operated circuit-breakers with overcurrent protection for household and similar purposes (RCBO) Part 1: General rules" and other standards.
Common models of DZ47LE series ELCB breaker includes DZ47LE-32/1P, DZ47LE-32/2P, DZ47LE-32/3P, DZ47LE-32/3P+N, DZ47LE-32/4P, DZ47LE-63/1P, DZ47LE-63/2P, DZ47LE-63/3P, DZ47LE-63/3P+N, DZ47LE-63/4P, they are current action type electronic leakage circuit breakers, consist of the DZ47 MCB and leakage release. When leakage or personal electric shock happen in the protection circuit, as long as the leakage current I △ reaches the operating current value, the circuit breaker will immediately take action to cut off the power supply, which play a role in leakage and electric shock protection, while ELCB breaker can also protect overload and short-circuit in the circuit.
