Schneider Electric LRD35 Thermal Overload Relay

Schneider Electric's TeSys LRD35 thermal overload relay provides motor protection for three-phase systems with a current-setting range of 30 to 38 A, designed to interrupt circuit current when overload conditions are detected and to protect motors and wiring in 690 VAC systems. As part of the TeSys LRD Deca family, the device includes a 1NO+1NC auxiliary contact, screw-clamp terminals for secure wiring, and a defined 10 A trip class, delivering repeatable protection characteristics when paired with TeSys Deca contactors. Schneider Electric notes that the LRD35 can protect 3-phase motors up to 18.5 kW at 400 V, aligning with its 30–38 A rating, and is designed for reliable installation in motor-control panels.
