Schneider Electric LRD10 Thermal Overload Relay 4–6A | TeSys D Motor Protection Relay
The Schneider Electric LRD10 Thermal Overload Relay is a premium motor protection relay engineered to safeguard three-phase motors against overload, phase failure, and prolonged overcurrent conditions. As part of the globally trusted TeSys D Series, the LRD10 features an adjustable current setting range of 4–6 Amps, making it ideal for protecting industrial motors used in pumps, compressors, conveyors, fans, HVAC equipment, and automation machinery.
Designed for seamless compatibility with Schneider Electric LC1D09 to LC1D38 contactors, the LRD10 enables the creation of a compact and dependable Direct-On-Line (DOL) motor starter. Featuring a Class 10A tripping characteristic, it allows motors to withstand normal starting currents while providing fast and accurate protection during overload conditions. The relay also incorporates phase-loss and load imbalance detection, helping prevent expensive motor failures caused by single phasing. With manual and automatic reset options, test and stop buttons, and built-in trip indication, the LRD10 offers easy operation and simplified maintenance.
Its compact design allows direct mounting beneath compatible TeSys D contactors, saving valuable panel space while ensuring quick installation. Built to international IEC standards, the Schneider LRD10 is trusted by OEMs, panel builders, electrical contractors, and maintenance engineers for reliable motor protection in demanding industrial environments.
