Description
DC 2P 50A MCB TOMC7-63 is used for overload and short circuit protection of lighting, power distribution lines and equipment in office buildings, residences and similar buildings, and can also be used for infrequent on-off operations and conversion of lines. Mainly used in various places such as industry, commerce, high-rise and civil residence. DC 2P 50A MCB TOMC7-63s break the circuit by mechanically separating the movable contact and the fixed contact of the miniature circuit breaker. When closing, the moving contact and the fixed contact are closed by the opposite mechanical movement.
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.
TONGOU Solar system DC MCB, apply to rating current 50A or less. It is mainly used for overloading and short circuit protection in DC distribution system equipment and electric equipment. It can be widely used in electric, post, traffic, mining enterprise and different kinds of fields.
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
