Description
TOMC3-63 AC 2P 40A MCB can deal with various types of failures, provide comprehensive protection for lines and equipment, avoid unnecessary power outages, and improve power supply reliability and safety.
It provides safer and smarter terminal electrical solutions for the power grid and hundreds of millions of home users.
2P 40A 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 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 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.
