Keep your electric motor running safely and efficiently with the help of this overload relay from Eaton. It switches a motor contactor on and off and signals a fault in the event of a phase failure or overcurrent, reducing the risk of your motor overheating or breaking. Screw terminals ensure wires are held firmly in place, even when equipment vibrates, which reduces the need for regular re-tightening and maintenance checks. Choose a relay like this for motor protection in factory and process automation applications.
