The LRD12S207 is a TeSys Deca differential thermal overload relay from Schneider Electric, designed for motor protection with a thermal protection adjustment range of 5.5...8 A and a class 10A trip curve conforming to IEC 60947-4-1. It provides phase failure sensitivity, tripping at 130% of Ir on two phases with the third at zero, and carries 1 NO + 1 NC auxiliary contacts for signalling the trip condition via the relay trip indicator.
Screw-clamp terminals accept 1...2.5 mm² flexible or solid for the signalling circuit and 1.5...10 mm² flexible for the power circuit, tightened to 1.7 N.m. Rated for operation from -40 to 60 °C without derating, with temperature compensation over that span. The IP20 enclosure suits clean, dry panel environments — not washdown or outdoor duty.
