It provides basic protection against overload, short-circuit, phase failure, phase imbalance, and earth faults for a 3-phase motor load. Rated for a 0.25 kW motor at 400...440 V AC 50/60 Hz, it uses a 24 V DC control circuit and draws 60 mA sealed (80 mA with LUB32 or LUB38 control modules) and up to 130-220 mA during closing, depending on the control module fitted. Thermal overload class is Class 10 with temperature compensation from -25 to 70 °C per IEC 60947-6-2 and UL 508. Utilisation categories AC-41, AC-43, and AC-44 cover switching and protection of motor loads under normal and occasional overload conditions. AC-44 is the most demanding — it certifies the unit for frequent inching and plugging duty, not just simple on-off motor starting. Tripping threshold is 14.2 x Ir ± 20 % for magnetic short-circuit protection. Rated insulation voltage is 690 V per IEC 60947-6-2, and 600 V per UL 60947-4-1 and CSA C22.2 No 60947-4-1. ## Where this class of part is used The TeSys U system is a modular motor starter that combines a power base, control unit, and communication or auxiliary modules in a single DIN-rail footprint. The LUCA1XBLTQ control unit plugs into the front of the power base and handles the protection logic and coil control. It is designed for motor control panels in industrial machinery, conveyors, pumps, fans, and compressors where a compact, coordinated motor starter with overload and short-circuit protection is needed. The plug-in design means the control unit can be swapped without rewiring the power base.","metaTitle":"Schneider TeSys U LUCA1XBLTQ Standard Control Unit, 24 V DC","metaDescription":"Standard control unit for TeSys U motor starter, 24 V DC coil, 0.25 kW at 400 V, Class 10 overload, IP20 front.
