Product Description

The FKN12 pneumatic load switch, also known as the FN12 high-voltage load switch, along with the FKRN12A-12D series of pneumatic load switch-fuse combination electrical appliances, are well-suited for controlling and safeguarding power equipment such as transformers, cables, and overhead lines within a three-phase power distribution system with a voltage of 12kV or below. They are particularly ideal for terminal substations and box-type substations in both urban and rural power grids. Moreover, they are applicable to the control and protection of ring network and dual-radiation power supply units.

The FKN12 series of pneumatic load switches are capable of switching on and off load currents and overload currents.

The FKRN12A-12D series of pneumatic load switch-fuse combination electrical appliances can switch on and off load currents and overload currents, and also interrupt the short-circuit currents of the lines.
