Description
AC 63A 1P Mini Circuit Breaker MCB TOMC3-63’s product performance is good, and the contact resistance is far below the standard requirements.
It can deal with various types of failures, provide comprehensive protection for lines and equipment, avoid unnecessary power outages, and improve transmission reliability and safety.
1P Mini Circuit Breaker Special Tips
1. Trip curve of B, C, D.
2. MCB is for non-professional operation by untrained personnel, without maintenance.
3. Choose a suitable trip curve and install it correctly. When a fault occurs, the MCB trips and cuts 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.
