Function Earth Leakage Circuit Breaker Auxiliary
APPLICATION
DZ47L High Breaking Earth Leakage Circuit Breaker is used in lighting distribution system or motor distribution system, with circuit of AC 50 Hz/60Hz, single-pole 230V or two, three, four-pole 400V, and rated current can be up to 100A, for overload and short-circuit protection as well as for unfrequent on-and-off switching electric motors in normal case.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 to protect the equipment from the fault resulted by the residual current. The products are widely used in the industry, commerce and dwelling, complying with the standard of IEC61900 and GB 16917.
