Schneider Electric LR2K012 Thermal Overload Relay

Schneider Electric LR2K012 Thermal Overload Relay is a TeSys LR2K differential overload relay designed to protect three‑phase motors when used with TeSys K contactors. As part of Schneider Electric's TeSys LR2K family, it coordinates with TeSys K starters to provide motor overload protection and can be reset manually or automatically depending on the model. The LR2K family is offered in multiple current ranges to suit motor ratings; examples in the LR2K0301–LR2K0322 family include LR2K0301 with a 0.11–0.16 A setting and LR2K0322 with a 12.0–16.0 A setting, reflecting the design goal of covering a wide range of motor sizes. The 3‑pole devices are compatible with 35 mm DIN rail mounting for clip‑on installation in industrial control panels, and many LR2K models feature a Class 10A trip characteristic to provide reliable overload protection in typical industrial environments. Applications include motor protection for conveyors, pumps, fans, and other 3‑phase equipment where easy integration with Schneider Electric relay and contactor hardware is advantageous.
