Adjustable Current ELCB Circuit Breaker NFC61450 / NFC62411 IEC60947 Standard differential current protection
GENERAL
An Earth-leakage circuit breaker (ELCB) is a safety device used in
electrical installations with high Earth impedance to
prevent shock. It detects small stray voltages on the metal
enclosures of electrical equipment, and interrupts the circuit if a
dangerous voltage is detected. Once widely used, more recent
installations instead use Residual Current Circuit Breakers which
instead detect leakage current directly.
The main purpose of Earth leakage protectors is to prevent injury to humans and animals due to electric shock.
There are two types of Earth-leakage circuit breaker:
· voltage operated (referred as ELCB in this article) and,
· current operated (referred to as RCCB in this article).
