Earth Leakage Circuit Breakers

Description

Earth Leakage Circuit Breakers (ELCB) are produced according to IEC/EN 60947-2 and CE standards. In adition to protect the overload and Short circuit currents, ELCBs protect the systems against Earth leakages. As the Leakage detection units are already in the body of circuit breakers, it is no need to use another Earth Lekage Relays and Torodial Transformers . on the other hand this product will not take more place in the panelboard and will be more economical.
