TOMC7-63 DC 1P MCB from TONGOU is used in direct current circuits (Industrial control and automations, transport, renewable energy). It combine the following functions of circuit protection against short-circuit and overload currents, control and isolation. It is C curve,whic can provide overcurrent protection for any type of application. The green strip indicates that all the poles are open and allows work to be carried out on the downstream circuit in complete safety.
1. MCB is for non-professional operation by those untrained, and no maintenance is required
2. Satisfying conditions and applications as mentioned above,MCB with “ON-OFF” indicating device is considered suitable for isolation function.
3. Particular devices such as surge protective devices,surge arrester etc are recommended to install at upstream line to MCB as precaution against potential surge voltage and current occurring at its power input side.
4. Appropriate tripping curve being chosen and properly installed, MCB trips and switches off its protected circuit in case of fault, and thus provides protection against electric shock.
