Trapped Key Interlocks - Switchgear Interlocking

 

Trapped key interlocks are commonly used for the safe and sequential operation of High and Low Voltage circuit breakers.

Through a pre-determined sequence of breaker operation and key transfer, the risks associated with incorrect switching can be mitigated through less reliance on switching procedures.
