| Description |
The KC Lock is a 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 bolt length and claw dimensions are variable to suit the particular requirement. The lock is manufactured in brass or stainless steel making it ideally suited to use in harsh or corrosive environments. |
| Operation |
| The bolt movement is directly controlled by the rotation of the key. With the key free, the bolt cannot be withdrawn, by inserting the key allows manual retraction of the bolt. The bolt length can be varied to suit the application and should be specified on ordering by quoting the 'A' dimension (see explanatory diagram).The claw details also need to be specified by quoting the 'B' and 'D' dimensions (see explanatory diagram). |
| Typical System |
1. Switch locked OFF. Claw ended bolt extended and locked. Key free.
2. Intermediate. Key inserted and turned. Bolt can be withdrawn.
3. Switch ON. Key trapped, bolt withdrawn. |
 |
| System Description |
