TOMC3-63 AC 2P 32A MCB from TONGOU is current limiting. They have two different tripping mechanisms, the delayed thermal tripping mechanism for overload protection and the electromechanic tripping mechanism for short circuit protection. TOMC3-63 series are available in different characteristics, configurations, breaking capacities and rated currents. All MCBs of the product range SH200 comply with IEC/EN 60898-1, allowing the use for residential applications.
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.
