TOMC3-63 AC 3P 25A MCB
TOMC3-63 AC 3P 25A MCB has the most advanced design with elegant appearance: curved cover and handle 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 high short-circuit capability. The locking device prevents accidental or arbitrary removal of the connected 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 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.MCB is for non-professional operation by those untrained, and no maintenance is required.
5. B,C,D tripping curve.
