Kirk Key interlocking switches are a means of safeguarding your equipment and critical data. You can use them to shut off power, control personnel access, and prevent a machine from starting when the guard is open.

To ensure safe and controlled access, a trapped key interlocking system like the Kirk Key is widely used with a UPS maintenance bypass. This method is an additional step in precautionary means for shifting utility power to backup battery power for maintenance and service. This feature eliminates the risk of accidentally dropping a data load.

A sequence of steps through transferring keys can either trap or release access to a locked or open circuit breaker. A key is used to isolate the power source with a bolt lock. Bolt interlocks have a variety of applications, from switchgear to machine guarding.

In access interlocking applications, a trapped key interlocking is used for preventing the paralleling of two energy sources, preventing particular operations until a breaker is locked open or closed, preventing disconnecting of breakers under load, and minimizing the possibility of a hazardous arc flash. These are often part of a larger trapped key interlock system.

A C&C Power maintenance bypass can easily be configured with a Kirk Key interlocking system. Options include either a basic Kirk Key system or an SKRU solenoid key release. Both come fully assembled and tested from the factory. If you have questions about which system is right for you, please contact our sales team for further information. Below is a visual walkthrough of a Kirk Key SKRU system. The goal of this video is to ensure you are interacting with the device confidently and correctly.
