WebApr 24, 2024 · Electrical overload can sometimes develop from ground faults (short-circuits in the motor windings or peripheral cables), but more commonly occurs due to jamming or improper operation. Overload protection relays prevent motor damage by monitoring the current in the motor circuit and breaking the circuit when an electrical overload or a … WebThe thermal overload relays are three pole relays with bimetal tripping elements. The motor current flows through the bimetal tripping elements and heats them directly and indirectly. In case of an overload (over current), the bimetal elements bent as a result of the heating. This leads to a release of the relay and a change of the contacts ...
