Schneider Electric LRD08 Overload Relay

The Schneider Electric LRD08 TeSys Deca thermal overload relay provides three‑phase motor overload protection for 690 VAC circuits, designed to mount directly to a TeSys contactor and aligning with the TeSys LRD/Deca family. This 3P device covers a current setting range of 2.5–4 A and includes an auxiliary contact (1NO+1NC) for interlock or feedback signals in control circuits. It uses screw‑clamp terminals on both the supply and load sides for secure, field‑serviceable wiring, and carries a class 10A thermal rating that defines its protective response characteristics. In operation, when motor current or temperature indicates overload, the relay trips to disconnect the motor via the contactor, helping prevent damage to pumps, fans, conveyors, and other industrial equipment. The LRD08 is widely used in automation and motor control installations where reliable, straightforward protection is essential, and it remains a standard option for Schneider Electric deployments involving TeSys contactors and accessories.
