Switchgear

Trapped key interlocks have a number of functions in substation switchgear applications. For example, 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.

Ship to Shore Power

When a ship comes to port and is mooring at dock, ships equipped with an Alternative Maritime Power (AMP) cable reel are able to shut down their generators, reducing noise and air pollution, and connect to land based power. This process is also known as cold ironing. Using KIRK® interlocks when connecting ship’s power cables to on shore power will ensure that the cables are properly coupled to the junction box before energizing.
