Schneider Electric LRD10 Thermal Overload Relay

The Schneider Electric LRD10 Thermal Overload Relay is a 3‑pole, adjustable motor protection device designed to mount directly to TeSys D contactors, delivering overload protection and phase failure detection for three‑phase motors in industrial control circuits. With a current adjustment range of 4 to 6 A and a Class 10A relay, it supports TeSys D contactors from LC1D09 to LC1D38 and offers either manual or automatic reset. It is commonly installed in motor starters, conveyors, pumps, compressors, and manufacturing equipment, and is suitable for motor control centers, electrical panels, and OEM machinery in demanding environments such as machine tools, HVAC equipment, and process control applications. Common replacements include ABB TA25DU-6.5 and Siemens 3RU2116-1FB0.
