General
Technical Parameter

FZN25- .12DL/T630- -20 indoor AC high voltage vacuum load switch is an indoor unit with three- phase AC of 50Hz, 12KV rated voltage, applicable to industrial and mining enterprises' power distribution stations and substations, etc. As the protection and control of electrical facilities, it is used for opening and closing load current, closed loop current, no-load transformer and cable charging current. It matches an earthing switch with the ability to close short-circuit current. The operating mechanism can be divided into manual and electric type, which is convenient for realizing the three remote control requirements of the power system. FZR25-12DL/T200-31.5 indoor AC high voltage vacuum load switch- fuse combination is an indoor unit with three- phase AC of 50Hz, 12KV rated voltage, applicable to industrial and mining enterprises' power distribution stations and substations, etc., as short circuit protection and load control. It matches an earthing switch with ability to close short- -circuit current.The operating mechanism can be divided into manual and electric type,which is convenient for realizing the three remote control requirements of the power system.
