Telemecanique LR2F5371 Thermal Overload Relay

The Telemecanique LR2F5371 thermal overload relay is a heavy‑duty three‑pole motor protection device that provides adjustable overload and phase‑loss protection for large three‑phase motors, with an adjustable current range of 125–200 A and a 3‑pole, direct contactor mounting design. It is rated for 600 VAC operation with 1500 VAC insulation and is compatible with Telemecanique F-series contactors—specifically F115, F150, and F185—for OEM direct replacement installations. Common in motor control centers, high‑power pumps, conveyors, crushers, and process equipment across manufacturing plants, mining operations, and water treatment facilities, the LR2F5371 serves as an OEM direct replacement with documented substitutes such as Schneider Electric LR2F5371 and Telemecanique LR2F5371.
