TOMC5-63 2P 40A MCB is a great circuit breaker used to protect an electrical circuit from damage caused by excess current resulting from an overload or short circuit. Fast closing to ensure reliable operation of the load and prolong the life of electrical circuit breakers. TOMC5-63 2P 40A MCB is easy and reliable to use, which supports short circuit protection, overload protection. It can be mounted conveniently on DIN rail, DIN rail is not included. TOMC5-63 2P 40A MCB is widely used for solar panels grid system, wind and solar hybrid system and many other DC system.

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.
5. B,C,D tripping curve(see graphics 1):

1.Protection against both overload and short circuit

2.Contact position indication

3.Applicable to terminal and pin/fork type Busbar connection

4.Easy mounting onto 35mm DIN rail
