2P 20A DC MCB TOMC7-63 is suitable for explosion-proof and plastic case design in the field of industrial production.
It has top fireproof materials to ensure complete flame retardancy. 2P 20A DC MCB TOMC7-63 uses silver dynamic and static electric shock, high-grade arc extinguishing material structure.
Because it can be installed with auxiliary switches, alarm switches, shunt releases and other functional elements, it can also monitor and control the electrical system.
20A DC MCB Special Tips
1. 20A DC MCB is for non-professional operation by untrained personnel without maintenance.
2. 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.
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. In order to meet the above conditions and applications, MCB with “ON-OFF” indicating device is considered suitable for isolation function.
