Symbol Earth Leakage Circuit Breaker Diagram

Forty years ago the first current eclbs were introduced and about sixty years ago the first voltage eclb was introduced.

Symbol earth leakage circuit breaker diagram. For many years the voltage operated elcb and the differential current operated elcb were both referred to as elcbs because it was a simpler name to remember. Early earth leakage circuit breakers are voltage detecting devices which are now switched by current sensing devices rcd rccb. Earth leakage circuit breaker. An earth leakage circuit breaker elcb is a safety device used in electrical installations with high earth impedance to prevent shock.

An voltage elcbs were first introduced about sixty years ago and current elcb was first introduced about forty years ago. Generally the current sensing devices termed as rccb and voltage detecting devices named as earth leakage circuit breaker elcb.
