10 ka MCB Three Pole Mini Circuit Breaker , High Short Circuit
UKB7 seires mini circuit breaker is applicable to electric circuits
with rated voltage 230/400V AC, frequency 50/60Hz and rated current
up to 125Amp. The product provides protection against voerload and
short circuit to electric circuits and equipments in household and
commercial installation. MCB is 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 35mm DIN rail

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