Breaking capacity:10 KA 1P 1P+N 2P 3O 3P+N 4P MCB Mini Circuit Breaker , High Short
Circuit & overload Capacity
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
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):
