AC 4P 16A MCB
TOMC3-63 AC 4P 16A MCB provides indirect protection to the operator’s body under such condition that the exposed live parts should be connected to a proper earthing pole.
It also provides protection against the fire danger caused by earth fault current due to function failure of over-current protection device.
AC 4P 16A MCB Special Tips
1. B, C, D tripping curve.
2. Choose a suitable tripping curve and install it correctly. MCB trips and cuts off its protected circuit when a fault occurs, thereby providing electric shock protection.
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. MCB is for non-professional operation by untrained personnel without maintenance.
5. To meet the above conditions and applications, MCB with “ON-OFF” indicating device is considered suitable for isolation function.
