Allen-Bradley 810-A16A Thermal Magnetic Overload Relay is a 100 A motor-protection device used in industrial control circuits. It combines thermal and magnetic trip mechanisms to guard a connected motor against overload, and is designed to be paired with compatible Allen‑Bradley contactors as part of a motor control circuit. This 810-series relay is intended for use in control panels and other industrial environments where motor protection is required. Typical applications include general-purpose motor protection in conveyors, pumps, fans, compressors, and machine tools.
