Switchgear Interlock FS

The FS Interlock is designed for use as a mechanical interlock for electricalswitchgear. The standard unit is fitted with a 9.5mm square x 22mm spigot that engages an actuating lever that can be used to operate an isolator or control access to a power distribution cubicle.

The key is normally trapped within the lock assembly. Turning the key moves the spigot through a predetermined angular position (45?-360?) isolating the supply and releasing the key. The free key can then be transferred to an access interlock.
