Description
AC 4P 25A Circuit Breaker MCB
TOMC3-63 AC 4P 25A Circuit Breaker MCB has two different tripping mechanisms, the delayed thermal tripping mechanism for overload protection and the electro mechanic tripping mechanism for short circuit protection.
They have C curve characteristics, and four pole configuration, breaking capacities up to 3kA at 110/220 V AC and rated currents up to 25 A.
4P 25A Circuit Breaker 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. Appropriate tripping curve being chosen and properly installed, MCB trips and switches off its protected circuit in case of fault, and thus provides protection against electric shock.
4. B,C,D tripping curve.
