oem FZ(R)N21-12D AC high voltage vacuum load breaking switch

FZN21-12D/T630-20 series three poles alternating current vacuum load break switch-fuse protector combination. It has merit of excellent breaking ability, small size, long electric life, free of maintenance, can break rated current, overload current (FZN21-12D/T125-31.5 can break short circuit current) and prevent device from phase-default operation. The switch has an obvious visible isolate fracture to assemble earth switch and electric spring mechanism, thus can conduct remote control.
