Advantages of DC Circuit Breaker MCB 1P,2P,3P,4P
1. DC Circuit Breakeris 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. Automatically disconnect the circuit when earth fault/leakage current occurs and exceeds the rated sensitivity.
6. Protection against both overload and short circuit
7. Contact position indication
8. Applicable to terminal and pin/fork type Busbar connection
9. Easy mounting onto 35mm DIN rail
