TeSys LRD4367 is a 3-pole differential thermal overload relay from Square D by Schneider Electric, part of the TeSys D family, rated 95–120 A and up to 600 V with a class 10A trip rating for 3‑phase motors. It is designed to mount with TeSys D contactors such as LC1D115–LC1D150 and features lug‑clamp terminations for secure wiring, with an auto/manual reset option for trip restoration. Used in IEC motor‑control circuits, it provides coordinated motor protection in 3‑phase applications and complements Schneider Electric’s LC1D‑series contactors for compact, integrated motor control.
