Description
TOMC5-63 2P 63A MCB
It is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by excess current, typically resulting from an overload or short circuit. Its basic function is to interrupt current flow after a fault is detected.
63A MCB Special Tips
1. MCB is for non-professional operation by those untrained, and no maintenance is required.
2. Choose a suitable trip curve and install it correctly, MCB will trip and close its protected circuit when a fault occurs, thereby providing 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.
