DC 2P 32A MCB TOMC7-63 is suitable for extreme environmental conditions, fast breaking, with excellent shock resistance and vibration resistance. It provide accurate overload and short-circuit protection for conductors and connected equipment, and it is suitable for extreme environmental conditions. DC 2P 32A MCB TOMC7-63 also can provide over-current and short-circuit protection for 3kv DC circuits.
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.
