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.
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. Particular devices such as surge protective devices, surge arrester, etc are recommended to install at upstream line to MCB as a precaution against potential surge voltage and current occurring at its power input side.
4. Appropriate tripping curve being chosen and properly installed, MCB trips and switches off its protected circuit in case of a fault, and thus provides protection against electric shock.
