It operates on a 24 V DC control circuit, drawing 220 mA maximum during closing and 80 mA sealed, with a drop-out threshold at 14.5 V DC. Rated for motor loads up to 15 kW at 400...440 V AC and 18.5 kW at 690 V AC, the unit carries utilisation categories AC-43 (motor starting, plugging, inching), AC-41 (resistive), and AC-44 (switching of motors at high operating frequencies). The thermal overload protection is Class 10, temperature-compensated from -25 to 70 °C, with a tripping threshold of 14.2 x Ir ± 20 %. ## Standards, approvals, and panel fit The LUCA32BLTQ complies with EN/IEC 60947-6-2, UL 60947-4-1, and CSA C22.2 No 60947-4-1 (with phase barrier), making it acceptable for panels destined for North American and European installations. Its front-face plug-in fixing mode means it snaps onto the TeSys U power base without tools — a time-saver during panel build or field swap. The unit measures 45 mm wide, 66 mm high, and 60 mm deep, fitting standard DIN-rail enclosures. IP20 on the front panel and wired terminals, IP40 on the front panel outside the connection zone — adequate for enclosed panel use but not for washdown environments. Safe separation of circuits is maintained at 400 V SELV between control/auxiliary and main circuits per IEC 60947-1, which simplifies panel wiring for compliance with low-voltage directives.","metaTitle":"Schneider TeSys U LUCA32BLTQ Standard Control Unit, 24 V DC","metaDescription":"Schneider Electric TeSys U LUCA32BLTQ standard control unit for motor starter, 24 V DC coil, 15 kW at 400 V AC.
