2P Mini Circuit Breaker Special Tips
1. MCB is for non-professional operation by untrained personnel without maintenance.
2. B, C, D trip curve.
3. It is recommended to install special devices on the upstream line of the MCB, such as surge protection devices, lightning arresters, etc., to prevent potential surge voltage and current from appearing on the power input side.
4. Choose a suitable trip curve and install it correctly. When a fault occurs, the MCB will trip and cut off its protected circuit, thereby providing protection against electric shock.
5. In order to meet the above conditions and applications, MCB with “ON-OFF” indicating device is considered suitable for isolation function.
