Description
TOMC3-63 AC 3P 25A MCB
TOMC3-63 AC 3P 25A MCB has the most advanced design with an elegant appearance: curved cover and handles make operation comfortable, contact position indication window, design a transparent cover with a label.
The handle cannot stay in this position during manual operation.
It has a high short-circuit capability. The locking device prevents accidental or arbitrary removal of the connection terminals.
AC 3P 25A MCB Special Tips
1. 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.
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 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. MCB is for non-professional operation by those untrained, and no maintenance is required.
5. B, C, D tripping curve.
