An earth-leakage circuit breaker (ELCB) is a safety device used in electrical installations to prevent shock. It consists of either a current sensing mechanism, or a voltage sensing mechanism. Such a protection mechanism may be found in the form of distribution board modules, standalone devices, and special sockets (aka receptacles). Voltage-operated ELCBs can still be found in the wild, though these largely fell out o
Earth Leakage Circuit Breakers (ELCB) are used to protect individuals from electric shock and for fire protection. They also serve the same function as MCCB. Comprehensive product range for
