The Schneider Electric LRD4365 Thermal Overload Relay is a motor protection device that safeguards three-phase motors from overload and phase loss conditions. Commonly installed with TeSys contactors in motor starters for pumps, conveyors, and other industrial machinery, it helps ensure reliable operation in manufacturing plants, HVAC systems, compressors, and material handling equipment. Part of the TeSys Deca (LRD) series, this 3-pole relay offers an adjustable current range of 80–104 A, a Class 10A trip rating, and protection for overload, phase loss, and phase imbalance with a rated voltage up to 1000 VAC. It provides 1 normally open and 1 normally closed auxiliary contact, mounts directly to a contactor or on a DIN rail with accessories, and features manual or automatic reset selection. Enclosure rating is IP20, and common replacements include LRD4369, LRD4363, and LR3D4365.
