Schneider Electric LRD340 Industrial Motor Starter

Schneider Electric's LRD340 TeSys LRD thermal overload relay provides motor protection for 30–40 A circuits with a class 10A rating, designed to be used with TeSys D contactors to form a compact motor starter. It supports 1 normally open plus 1 normally closed (1NO+1NC) contact configuration and is rated for operation up to 690 VAC, delivering reliable thermal protection for three‑phase motors in industrial settings. The LRD340 is available with EverLink compatible terminals (screw‑terminal variant) for quick, secure wiring, and it can be mounted directly with TeSys D devices to create a streamlined, space‑saving starter assembly. Typical applications include conveyors, pumps, fans, and other machinery that require integrated overload protection and straightforward start/stop control.
