H series moulded case circuit breaker has novel
structure, reliable performance, complete accessories and high interrupting
capacity. It is suitable in the distribution circuits of AC in 50/60Hz,
working voltage up to 600V, and used for power distribution and
protecting the circuits and electrical equipment against overload.
It is in conformity with the standards of IEC 157-1, and consists
of 4 parts: insulating case, operating
