LR2K0303 is a TeSys LRK thermal overload relay from Schneider Electric to be used with a TeSys K contactors. It protects motors 0.06-0.09kW@400V thanks to a thermal range 0.23-0.36A, a tripping class 10A and phase unbalance protection. LR2K0303 is a TeSys LRK thermal overload relay from Schneider Electric for direct mounting on TeSys K contactors. With a thermal setting range 0.23-0.36A, a tripping class 10A and phase unbalance detection, it protects motors 0.06-0.09kW@400V. It provides manual test & reset buttons, automatic reset, trip auxiliary contact and flag indicator. Available worldwide, it is multi-standards certified (IEC, UL, CSA, CCC, EAC, Marine) and Green Premium compliant (RoHs/Reach). Thermal overload protection relay, bimetallic type, with phase unbalance protection (differential). Direct mounting on the bottom terminals of a Tesys contactor LC1K06 to form a compact starter. Light and compact, 45mm wide. Manual control with test & reset buttons, manual / automatic reset selector. Trip signaling with 1NO+1NC auxiliary contacts and trip flag indicator. Can be completed with terminal blocks for separate mounting (LA7K0064).
