FZ(R)N25-12D Indoor Load Break Switch Load Breaker Isolator Isolate Switch
Manual opening and closing operation is normally on the right side of the load switch, and the front or leftside operation can be provided according to the user's requirements.
FZN25-12D/T630-20 type indoor ac high voltage load switch is three-phase ac 50 Hz, rated voltage of 12kv indoor device, applicable to industrial and mining enterprises substation and transformer substation, etc, asprotection and control of electrical faclities, used to close and open the load current, closed loop current, no-load transformer and cable charging electric current.
FZRN25-12D/T125-31.5 type indoor ac high voltage vacuum load switch and fuse-combination unit isthree-phase ac 50Hz, rated voltage of 12 kv indoor device, applicable to industrial and mining enterprisessubstation and transformer substation, etc, as load control and short circuit protection.Equipped with groundingswitch, can withstand short-circuit current.Operating mechanism can be manual and electric, easy to realize the three remote control requirements of power system.
FZN25-12D,FZRN25-12D type load switch and fuse-combination unit suitable for three-phase ring orterminal power supply of the urban distribution substation and industrial electrical equipment, as load control andshort circuit protection. Because the protection effect of combined appliances on transformers and otherelectrical equipment is more reliable and more economical than circuit breakers, it is especially suitable for ringnetworks, double-radiation power supply units and box-type substation
