Schneider Electric LR2K0310 Power Contactor 3-Phase

Schneider Electric LR2K0310 is a differential thermal overload relay in the TeSys K family, designed to provide motor overload protection in three-phase circuits when paired with TeSys K IEC contactors. The LR2K0310 offers a current setting range of 2.6 to 3.7 A and carries a class 10A thermal rating, enabling precise protection for small to mid-size three-phase motors in industrial equipment such as conveyors, pumps, and processing lines. When integrated with TeSys K contactors, LR2K0310 forms a compact, modular motor-protection solution that can be field-adjusted to match a motor's full-load current, delivering reliable shutdown in fault conditions while supporting routine maintenance and panel layouts that favor a single, standardized protection module. In panel installations, the LR2K0310 helps simplify wiring and serviceability by integrating into the TeSys K protection stack.
