The K Lock is a key operated mechanical bolt interlock that is
suitable for the control of electrical switchgear. The standard unit
comes with a 15.88 mm diameter bolt available in various lengths,
that is used to control the rotation or movement of operating
handles or toggles of electrical switchgear. Many suppliers of
switchgear equipment have mounting kits available for Castell‘s
interlocks. The lock is manufactured in brass or stainless steel
making it ideal for use in harsh or corrosive environments.
1. While the side bolt is extended, the key is free. The mechanism is locked.
2. By inserting and turning the key in the bolt interlock, you can retract the bolt, releasing the disconnector. This
will trap the key into the lock.
3. The key stays trapped while the bolt is retracted.
The length of the bolt is available in various lengths to suit the application, but the travel of the bolt is always 19,05 mm. The key
is free when the bolt is extended. Insertion and rotation clockwise of the key will retract the bolt. The key will be trapped in the
bolt retracted position.
