on video Working Principle Of Earth Leakage Circuit Breaker(ELCB)

 

Early earth leakage circuit breakers are voltage detecting devices, which are now switched by current sensing devices (RCD/RCCB). Generally, the current sensing devices termed RCCB, and voltage detecting devices named Earth Leakage Circuit Breaker (ELCB). Forty years ago, the first current ECLBs were introduced and about sixty years ago the first voltage ECLB was introduced. For several years, both the voltage and current operated ELCBs were both referred to as ELCBs due to their simple name to remember. But the applications of these two devices gave growth to the significant mix-up in the electrical industry. The manufacture of ECLB includes Fuji Electric, Major Tech, Siemens, ABB, Avera T&D, Telemecanique, Camsco, Crabtree, Orion Italia, Terasaki, MEM, and V guard.
