K
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.

Application
The power supply to the system is switched on and the
access doors to the hazardous area are locked closed.
Key A is trapped in the disconnector K Lock while the
process is on.
To enter the area, the disconnector is turned to the off
position and key A is released, locking the disconnector
in the disengaged position.
Key A is then taken to the grounding switch. Key A
enters the K lock which retracts the bolt enabling the
cammed switch lever to be rotated to engage the
ground. Once rotated, the recess in the cam aligns with
the second K lock. Key B from the second K lock can
now be removed which now locks the lever in place en-
suring that the ground connection cannot be broken.
Now that the system is disconnected and grounded, key
B can be released to operate the access interlock and
gain access to the dangerous area.
