It handles a 15 kW motor at 400...440 V AC, with the same power rating at 500 V and stepping up to 18.5 kW at 690 V AC. The unit is self-cooled and requires manual reset after a trip — no auto-restart, so it's suited for attended machinery where a technician must clear the fault before re-energizing. Rated for 15 kW at 400 V AC in AC-41/AC-43/AC-44 utilization categories — that covers resistive, motor, and mixed loads in standard industrial motor control centers. The tripping threshold is 14.2 × Ir, a short-circuit protection level that coordinates with downstream contactors and upstream breakers. Control circuit is 24 V DC, drawing 220 mA peak on close and 80 mA sealed — a standard PLC output can drive it through a suitable relay. Plug-in front-face mounting, 45 mm wide, 66 mm high, 60 mm deep — fits standard TeSys U power bases and busbars. IP20 on the front panel and wired terminals, IP40 on the front panel outside the connection zone. The control circuit is SELV-rated at 400 V from the main circuit per IEC 60947-1, so it can share a 24 V DC bus with other control devices without isolation transformers. Rated for operation up to 2000 m altitude without derating.","metaTitle":"Schneider TeSys LUCB32BLTQ Advanced Control Unit","metaDescription":"Schneider TeSys U LUCB32BLTQ advanced control unit. 15 kW at 400 V, manual reset, IP20.
