1. Mini Circuit Breaker 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.
Mini Circuit Breaker (MCB), also known as miniature circuit breaker, is a current-limiting, high-breakage miniature circuit breaker with overload and short-circuit double protection.TOMD6 is the new generation of products from Tongou，it is suitable for AC 50Hz/60Hz, rated voltage 230V, rated current up to 63A and below in the circuit, as line overload and short circuit protection. With advanced structure, reliable performance, strong breaking capacity, beautiful and compact appearance, etc., the miniature circuit breaker is widely used in industrial, commercial, high-rise and civil housing and other places.
