Scope of Application

DZ*7LE**3 Residual Current Circuit Breaker (rccb) is used for the line of AC *0Hz, rated voltage of **0V, rated current of *0A, 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 IEC******1: ***6, GB****7.1 "Residual current operated circuit-breakers with overcurrent protection for household and similar purposes (RCBO) Part 1: General rules" and other standards.
