Description
TOMC5-63 3KA Curve C 63A MCB 4 Pole
Curve C 63A MCB 4 Pole TOMC5-63 is current limiting. It is suitable for a delayed thermal tripping mechanism for overload protection and the electromechanical tripping mechanism for short circuit protection.
All MCBs of the product range TOMC5-63 comply with IEC/EN 60898-1, IEC/EN 60947-2, AS/NZS 60898.1, allowing the use of residential, commercial, and industrial applications.
MCB 4 Pole 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. 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. 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.
