Schneider Electric LRD10 Thermal Overload Relay

Schneider Electric’s TeSys LRD10 thermal overload relay provides three‑pole motor protection for three‑phase systems when paired with TeSys D contactors, delivering reliable overload and phase‑loss protection in industrial motor control applications. This adjustable overload relay covers a current range of 4–6 A and features Class 10A tripping characteristics, helping prevent motor damage in environments such as motor control centers, conveyors, pumps, compressors, fans, HVAC equipment, and manufacturing machinery that use TeSys D starters. The unit is rated for 690 VAC (600 VAC UL/CSA), supports 3‑pole operation with 1 NO + 1 NC auxiliary contacts, and offers mounting options including direct contactor mount, DIN rail, or panel mounting with appropriate accessories. Wiring is via screw clamp terminals for secure connections. Compatible TeSys D contactors include LC1D09, LC1D12, LC1D18, LC1D25, LC1D32, and LC1D38. The LRD10 is an OEM direct replacement and is part of Schneider Electric’s TeSys LRD (TeSys Deca) family, designed for use in environments from −20°C to +60°C. Common replacements and cross‑compatibility exist under Schneider Electric LRD10 and Telemecanique LRD10 designations, making it a practical choice for repair, retrofit, or new installations in control panels, material handling systems, water treatment plants, packaging lines, and machine tools where dependable motor protection helps maximize uptime and motor life.
