High pressure gas pressure load break switch FKRN12-24D

High pressure gas pressure load break switch FKRN12-24D

General

FKRN12-24D series high pressure gas pressure load switch and its combination eleCTric appliance are AC 24KV, 50Hz indoor high voltage Switchgear. The load switch has the characteristics of high technical parameters and reliable operation. The basic form of the operating mechanism is manual spring energy storage type. It can be equipped with electric spring operating mechanism, based on the principle of air pressure and arc extinguishing, so it can be divided multiple times without replacing the arc extinguishing tube.

The high-voltage load switch can close, load and break the load current under normal circuit and has the ability to close the short-circuit current and carry the short-circuit current for a specified time.

The FKRN12-24D series load switch can be equipped with a grounding switch. The grounding switch has the same short-circuit current closing capability as the load switch, as well as dynamic thermal stability, and has a strict mechanical interLock with the load switch, which is structurally impossible misuse.
