Description
63A MCB Switch Mini Circuit Breaker
TOMC5-63 3P 63A MCB switch is applied at direct current circuit system, with rated operation ovltage DC 220V, rated current upto 63A, to make protection of overload and short circuit, also for infrequent changeover for the lines.
The breakers are used at places of commercial offices, residential and similar buildings.
3P mcb switch meets standards of GB 10963.2 and IEC 60898-2, at an advanced international level.
Feature
1. MCB is for non-professional operation by those untrained, and no maintenance is required.
2. 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.
3. Particular devices such as surge protective devices, surge arresters, etc are recommended to install at the upstream line to MCB as a precaution against potential surge voltage and current occurring at its power input side.
4. Satisfying conditions and applications as mentioned above, MCB with “ON-OFF” indicating device is considered suitable for isolation function.
5. B, C, D tripping curve(see graphics 1):
