The Schneider Electric LRD05 is a three‑pole TeSys Deca thermal overload relay that protects AC motors and forms a compact motor starter when mounted with a TeSys D contactor. It covers a current range of 0.63–1 A and is rated for up to 690 V AC with a class 10A trip designation. The device provides one normally open and one normally closed auxiliary contact and uses screw‑clamp terminals for secure wiring. Typically used with TeSys D starters to guard against overload, phase loss, and extended startup transients in small- to mid-size motor circuits.
