It continuously monitors the current flowing through an electrical circuit and trips or disconnects, the circuit when the current exceeds a predetermined level.
WebDec 24, 2024 · How does an overload relay work? The overload relay is wired in series with the motor, so the current that flows to the motor when the motor is operating also flows through the overload relay. It will trip at a certain level when there is excess current flowing through it. This causes the circuit between the motor and the power source to open.
