Schneider Electric LRD340 Thermal Overload Relay

Schneider Electric TeSys Deca LRD340 thermal overload relay protects 690 VAC motors in TeSys D starter configurations by interrupting current when an overload is detected. With a rated current range of 30 to 40 A and a class 10A trip, it provides precise motor protection for moderate‑sized drives. The unit includes a built‑in 1 normally open and 1 normally closed auxiliary contact for signaling or interlocking in the control circuit, and it uses EverLink BTR screw terminals for durable field wiring. As part of the TeSys Deca family, the LRD340 is designed to be paired with TeSys D contactors to form a complete motor starter, delivering coordinated protection and control for industrial motors up to 690 VAC. The LRD340’s compact footprint and screw‑terminal connectivity support straightforward panel integration in standard industrial control panels.
