Molded Case Circuit Breaker Has Leakage Protection?

Plastic case circuit breakers are used to protect electrical equipment and can interrupt the fault current. With overload protection, short circuit protection, there is a circuit breaker called residual current operated circuit breaker. Its use is the same as a plastic shell circuit breaker.

 It also has overload protection and short circuit protection. The only difference is the addition of leakage protection on the basis of plastic case circuit breakers. Such residual current operated circuit breakers are often used in low-voltage power distribution cabinets. As a main power supply or branch power supply, a power distribution system is formed together with a plastic case circuit breaker.

The principle of leakage protection is that when the human body has an electric shock, the current will flow through the body to the earth. At this time, the zero-sequence current transformer in the residual current action circuit breaker will detect the presence of residual current (the three-phase current combination is no longer Zero), when the residual current reaches a certain size, the leakage release will drive the tripping mechanism of the circuit breaker to trip the circuit breaker and protect personal safety.

This residual current operated circuit breaker has more functions than a plastic shell type circuit breaker, but it cannot completely replace the plastic shell type circuit breaker, which occupies most of the market with the advantage of price. MAXGE is a plastic shell type leakage circuit breaker manufacturers
