Description
3P 16A Circuit Breaker MCB
AC 3P 16A Circuit Breaker MCB TOMC3-63 is mainly used for protecting against overload and the short circuit under 50/60Hz, rated voltage 110/220V and rated current from 1A to 63A.
3P 16A Circuit Breaker MCB has a neoteric structure, fast-breaking, prompt arc extinguishing, and short tripping features.
3P 16A Circuit Breaker MCB Special Tips
1. MCB is for non-professional operation by untrained personnel without maintenance.
2. B, C, D trip curve.
3. 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.
4. 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.
5. In order to meet the above conditions and applications, MCB with an “ON-OFF” indicates the device is considered suitable for isolation function.
