FZN25-12D Series Indoor High Voltage Vacuum Load Switch + Fuse Combination Appliance

Short Description:

FN25-12D/T630-20 indoor AC high-voltage load switch Three-phase AC 50Hz. Indoor installation with rated voltage of 12KV. It is suitable for distribution and substation of industrial and mining enterprises, as the protection and control of electrical facilities, for dividing load current, closed-loop current, no-load transformer and cable charging current. FZRN25-12DmD-31.5 type indoor AC high-voltage vacuum load switch fuse combination is a three-phase AC 50Hz, rated voltage 12KV indoor device, suitable for industrial and mining enterprises distribution offices and substations and other fields. For load control and short circuit protection. Equipped with the ground switch, can withstand the short-circuit current, the operating mechanism can be manual and electric, cheaper to achieve the three remote control requirements of the power system. FZN25-12D, FZRN25-12D type load switches and combined electrical appliances are suitable for three-phase ring network or terminal power distribution stations and industrial electrical equipment, for load control and short circuit protection because the combination of electrical appliances for transformers and other electrical equipment protection than circuit breakers more reliable, more economical, especially suitable for ring network, double radiation power supply units and box-type substations.
