Schneider Electric LR3D06 is a thermal overload relay from the TeSys D family, designed to protect motors against overload, phase failure, and phase imbalance. It operates within a current range of 1 to 1.6 Amperes and is compatible with AC and DC control circuits. The relay measures 2.6 in (66 mm) in height, 1.8 in (45 mm) in width, and 2.8 in (70 mm) in depth, with a weight of 0.306 lb, and features a compact, modular construction for direct mounting on contactors. It complies with multiple international standards including EN/IEC 60947-4-1, EN/IEC 60947-5-1, UL 60947-4-1, UL 60947-5-1, CSA C22.2 No 60947-4-1, CSA C22.2 No 60947-5-1, GB/T 14048.4, GB/T 14048.5, and EN 50495. This overload relay is typically used in industrial motor control applications for conveyors, pumps, fans, and compressors requiring precise thermal protection.
