TOMC5-63 Mini Circuit Breaker MCB
3KA 110V 220V Curve C 4P 40A Mini Circuit Breaker MCB with 40A current rating and trip curves B, C, and D for selection.
The 3kA breaking capacity mini circuit breaker, mounted on a standard 35mm DIN rail, makes it ideal for commercial and industrial IEC applications.
Mini Circuit Breaker MCB Special Tips
1. MCB is for non-professional operation by those untrained, and no maintenance is required.
2. B, C, D tripping curve.
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. 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.
5. To meet the above conditions and applications, MCB with an “ON-OFF” indicates the device is considered suitable for isolation function.
