Schneider Electric LR3D14 is a TeSys LRD thermal overload relay designed for motor protection, providing non-differential thermal protection with a class 10A tripping characteristic. It supports a current rating of 7 to 10 A and operates on AC or DC networks with a frequency range of 0 to 400 Hz, featuring a rated insulation voltage of 600 V (CSA/UL) and 690 V (IEC). The device 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 0.313 lb, and is constructed for direct mounting compatibility with TeSys D 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 applied in industrial motor protection circuits for three-phase motors requiring thermal overload and phase loss protection.
