3KA 110V 220V Curve C 4P 63A MCB Mini Circuit Breaker
AC 4P 63A MCB TOMC3-63 has an elegant appearance; curved cover and handles make operation comfortable with a contact position indication window.
AC 4P 63A MCB is designed with a transparent cover for the label. When an overload occurs, in order to protect the circuit, the MCB handles trips and stays in the center position, which can make the fault line a fast solution.
The handle cannot stay in this position during manual operation. MCB handle can be locked in the “ON” position or “OFF” position to prevent unnecessary operation of the product.
4P 63A MCB Special Tips
1. MCB is for non-professional operation by those untrained, and no maintenance is required.
2. 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.
3. B, C, D tripping curve.
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.
