Description
NBSB1-63 NBSe ( New Blue Sky Electrical ) Mini Micro Circuit Breaker Switch 4 Pole 40A 6KA,10KA 120V/230V /400V For Industrial / Home RoHS
NBSe NBSB1-63 Series 4P 40A Mini Circuit Breaker, circuit breaker switch
A mini circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit. Its basic function is to detect a fault condition and interrupt current flow. Unlike afuse, which operates once and then must be replaced, a circuit breaker can be reset (either manually or automatically) to resume normal operation. Circuit breakers are made in varying sizes, from small devices that protect an individual household appliance up to large switchgear designed to protect high voltage circuits feeding an entire city.
1. Application
NBSB1-63 is mainly used in AC50/60Hz single pole230V or two,three,four pole 400V voltage for overload and short-circuit protection as well as for unfrequent on-and-off switching electric equipment and lighting circuit under nrmal conditionl
the product is suitable for industry,business,building,ressidence,etc.
It’s conformity with CE GB10963,IEC60898 EN898 standards.
