Residual Current Circuit Breakers
What is the difference between a residual current circuit breaker and a leakage protector?
Residual current circuit breaker is a relay protection device that can automatically disconnect the circuit or send an alarm signal when the residual current in the protected circuit exceeds the set value under specified conditions.
Leakage protector only has the function of leakage tripping, which is used to effectively protect the low-voltage power grid from direct and indirect electric shocks. Residual current circuit breakers can also be used as a phase-loss protection for three-phase motors. It has single-phase and three-phase.
