Allen-Bradley X-243981 is a three-pole overload relay engineered for 3‑phase motor protection. It uses a eutectic alloy thermal element (WL44 heater) and mounts on a DIN rail in an open-style enclosure, with screw-terminal wiring for straightforward installation. The device supports a wide control power range of 115–230 VAC or 24 VDC, operates at 50–60 Hz, and allows a peak operating voltage up to 600 VAC. With a trip class of 30, it is designed for 3‑phase circuits and weighs about 1.0 lb (0.45 kg).
