Schneider Electric LRD05C Thermal Overload Relay

Schneider Electric TeSys LRD05C thermal overload relay is a three‑pole device in the TeSys Deca family designed to protect three‑phase motors in AC circuits from overload. It is rated for 0.63 to 1 A per phase and up to 690 V AC, delivering class 10A protection. The auxiliary circuit provides 1 normally open and 1 normally closed contact for status signaling or interlocking with control circuits, and wiring uses screw clamp terminals for secure connections. Designed to work with TeSys D contactors, the LRD05C enables a compact motor starter configuration suitable for equipment such as conveyors, pumps, and fans in 690 VAC environments. This model is the LRD05C variant of Schneider Electric's LRD thermal overload relay family, which are described in Schneider Electric documentation as differential overload relays built to protect AC motors against overload across standard industrial applications.
