Disconnecting Switch Production Description

QP Series Isolating Switch Fuse Group primarily for high short-circuit current of the power distribution circuit and motor circuit, as the manual does not frequently operated power switch, isolating switch and emergency switch, and as a short circuit protection purposes.

QP isolation switch with full-closed interrupter system, no flying arc; multi-breakpoint double contact system of patent protection by the State, set load breaking and isolation in one, comprehensive overload and short circuit protection; can directly open and close electric motors and high capacity nature of the load; more spring energy storage, switching operation and human has nothing to do; small size, high capacity, security and more reliable.
