The Eaton Cutler-Hammer AA23A Thermal Overload Relay interrupts current when motor overload or overheating is detected to protect electric motors in operation. Designed for use with Cutler-Hammer motor starters, it integrates into motor control circuits in control panels to provide thermal protection. The AA23A designation identifies this unit within Eaton’s Cutler-Hammer line as a thermal overload relay for motor protection in AC motor systems.
