GENERAL
STG series adjustable residual current circuit breaker is suitable for AC 50/60Hz,230/400V circuit,prevents from overloading,short-circuit etc.On the occasion of shock hazard or earth leakage,it will trip immediately.At the same time,the rated current of overload protection can be adjustable.
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.
