A disconnect relay is an electromechanical device used to isolate parts of an electrical circuit for safety or maintenance purposes. When activated, it opens the circuit by breaking the connection between the power source and the load, preventing current flow. This is typically controlled by an external signal, such as from a protective relay or a manual switch. Once the relay is disengaged, it can safely allow maintenance personnel to work on the equipment without the risk of electric shock.
