Isolation Switch

QSA 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.

QSA 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.

QSA series switch must be equipped with in line with IEC269 and have a corresponding short-circuit breaking capacity and rated voltage of the fuse body. For application of fuse signal device must be used with a fuse of the fuse body impactor.

QSA series switch for the first time will be supporting the insulating partitions should be preceded in turn plugged, and then into the fuse body. For the blade-type contact fuse should be inserted in place, for the screw-type fuse link should pay attention to tightening bolts.

QSA Series switches used must be supporting the use of fuse. Then fuse can be owned by the user. Note Be sure to select the best fuse to prevent high temperature.
