2P 32A DC MCB TOMC7-63 is suitable for extreme environmental conditions, fast breaking, with excellent shock resistance and vibration resistance.
It provide accurate overload and short-circuit protection for conductors and connected equipment, and it is suitable for extreme environmental conditions.
2P 32A DC MCB TOMC7-63 also can provide over-current and short-circuit protection for 3KV DC circuits.
32A DC MCB Special Tips
1. MCB is for non-professional operation by those untrained, and no maintenance is required.
2. Choose a suitable trip curve and install it correctly. MCB will trip and close its protected circuit when a fault occurs, 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. Satisfying conditions and applications as mentioned above,MCB with “ON-OFF” indicating device is considered suitable for isolation function.
