MCB Housing OverView
TOMP65-32 1p n MCB housing miniature circuit breaker is a multi-standard circuit breaker that combines the following functions：
-Circuit protection against short-circuit currents,
-Circuit protection against overload currents,
MCB Housing 1P N Description
- 1P N MCB housing is for non-professional operation by those untrained, and no maintenance is required.
- Satisfying conditions and applications as mentioned above, MCB with “ON-OFF” indicating device is considered suitable for isolation function.
- Particular devices such as surge protective devices and surge arresters are recommended to install at the upstream line to MCB as a precaution against potential surge voltage and current occurring at its power input side.
- 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 overcurrent and short-circuit.
B, C, D Tripping Curve
The curve types of B, C, or D depending on the tripping current rating at which instantaneous operation occurs (generally less than 100ms) to protect against the short circuit.
