Description
AC 2P 16A MCB
TOMC3-63 AC 2P 16A MCB has two different tripping mechanisms, the delayed thermal tripping mechanism for overload protection and the electromechanical tripping mechanism for short circuit protection.
TOMC3-63 series are available in different characteristics, configurations, breaking capacities, and rated currents.
AC 2P 16A MCB Special Tips
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. It is recommended to install special devices, such as surge protection devices, lightning arresters, etc., on the upstream line of the MCB to prevent potential surge voltage and current from appearing on the power input side.
4. B, C, D tripping curve.
5. 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.
