The LRD15126: The 5.5...8 A thermal protection adjustment range sets the motor full-load current window — set the dial to match the motor nameplate FLA. The phase-failure sensitivity trips at 130 % of Ir on two phases with the third at zero, which catches a lost phase before the motor overheats. Auxiliary contacts are 1 NO + 1 NC, rated 1.5 A at 240 V AC-15 and 0.1 A at 250 V DC-13 for signalling circuits. The relay mounts under a TeSys contactor or on a plate/rail with accessories, and its IP20 finger-safe enclosure suits enclosed panel installation.
