UKB7 2P high breaking capacity Mini Circuit Breaker B/C/D curve 6,10,16,20,25,32,40,50,63A
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.

Tips:
1. MCB is for non-professional operation by those untrained, and no maintenance is required
2. Satisfying conditions and applications as mentioned above,MCB with “ON-OFF” indicating device is considered suitable for isolation function.
3. Particular devices such as surge protective devices,surge arrester etc are recommended to install at upstream line to MCB as precaution against potential surge voltage and current occurring at its power input side.
4. Appropriate tripping curve being chosen and properly installed, MCB trips and switches off its protected circuit in case of fault, and thus provides protection against electric shock.
