General:
HUM18-125 series miniature
circuit breaker (MCB) is applied to protect the over-current of
electrical apparatus and circuit device of construction and similar
building in the circuit with rated frequency of AC 50Hz, rated
voltage of 230V/400V and max rated current of 125A. It can also be
applied as the infrequent make-break operation. Pole number is
from1 pole up to 4 poles.
The rated limit short circuit breaking capacity is 10kA and
mechanical lifetime is 20,000 times.
This product conforms to the standards of IEC60898: 1995 and
GB10963-1999 (requirements of over-current protection circuit
breaker for household or other uses).
