UKB7 seires mini circuit breakers  are applicable to electric circuits with rated voltage 230/400V AC, frequency 50/60Hz and rated current up to 63Amp. The products provide protection against voerload and short circuit to electric circuits and equipments in household and commercial installation. MCBs are also used as non-frequent changeover of electric circuits.





1. Protection against both overload and short circuit


2. High short-circuit capacity


3. Contact position indication


4. Applicable to terminal and pin/fork type busbar connection


5. Easy mounting onto 1~25 mm²  DIN rail

1. MCBs are for non-professional operation by those untrained, and no maintenance is required


2. Satisfying conditions and applications as mentioned above,MCBs with “ON-OFF” indicating device are considered suitable for isolation function.


3. Particular devices such as surge protective devices,surge arresters etc are recommended to install at upstream line to MCBs as precaution against potential surge voltage and current occurring at their power input sides.


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.


5. B,C,D tripping curve(see graphics 1):
