KLC – Dual Key Claw Interlock Mechanical Isolation The KLC dual key claw interlock is a multi-key operated mechanical bolt interlock suitable for the control of electrical switchgear. The standard unit comes with a 16mm diameter bolt fitted with a claw that is used to control the rotation or movement of operating handles or toggles of electrical switchgear. The lock is manufactured in brass or stainless steel. OPERATION The Castell claw interlocks range is used in switchgear control to lock off power supply and control accesses to hazardous areas. The length and the travel of the bolt can be varied to suit the application.

The KLC claw interlock is not designed for security purposes, such as access to a building. No hazardous substances were used in the manufacture of this product APPLICATION The KLC claw interlock safety component is used as a part of an integrated safety system, typically in machine guarding applications. It is usually used in combination with an access interlock such as the AI for part body access or an access interlock with an exchange key for full body access control such as AIE. While the power supply is switched on, both keys are trapped in the KLC claw interlock. To lock off the power supply switch, drive the bolt to extended position.
