Schneider Electric LRD08 Relay

Schneider Electric TeSys LRD08 thermal overload relay protects 3‑phase motors in 690 VAC systems by automatically interrupting current when the motor draws more than the set range. The LRD08 covers a load current range of 2.5 to 4 A (3P, 690 VAC, 50/60 Hz) and includes one normally open and one normally closed auxiliary contact (1NO+1NC) for signaling in the control circuit, with screw‑clamp terminals for secure wiring. It’s rated for Class 10A overload protection and is designed to be used with TeSys contactors as part of a motor‑protection scheme, commonly applied to pumps, fans, conveyors, and other machinery where reliable overload protection is critical. This relay is part of Schneider Electric’s TeSys LR.D/Deca family and provides differential thermal protection that helps prevent overheating and motor damage in demanding industrial environments.
