Product Description
GW (F)- 12 R / 200-6.3 outdoor alternating HV disconnecting load switch is a
equipment under 50Hz three-phase A.C. voltage. It is suitable for 10kV overhead
distribution lines to on/off low-loading current outdoor where it is not very
important places and short circuit accidents appear infrequently. This product
is three-phase linkage type with the ability to break load current under 200A,
and have the protecting function of short circuit current after being installed
with ordinary 10 kV fuse with obvious isolation clearance. This product have
advantages such as embedded pole, reasonable design, simple structure, complete
function, reliable action, small volume and light weight, etc.
