How an overload relay works
WebThermal overload relays work on the principle of heat and temperature rise. When an electrical current flows through a conductor, heat is produced which causes the conductor to have an increased temperature rise. When the temperature rise reaches a predetermined set point, the relay will act to open the protected circuit. Web10 de fev. de 2024 · An overload relay is an electrical protection device that is used to prevent damage to electrical equipment and components from excessive current. It continuously monitors the current flowing through an electrical circuit and trips or disconnects, the circuit when the current exceeds a predetermined level.

WebThe contacts of a thermal overload relay close or open depending on the degree of heat produced by the current through the relay’s coil that is connected in series with the protected load. Since there is a definite time interval between the current flow and the heat produced by the coil, thermal overload relays are used for overload protection. Weboverload relay that helps protect the motor, and reducing th e cost of the overload relay. For retrofit applications, you can place split-core CTs around each phase conductor and mount the overload relay elsewhere in the panel, providing flexibility and time savings because the power conductors do not need to be disconnected.
