It integrates protection against overload, short-circuit, phase failure, phase imbalance, and earth faults, with a manual reset function. The 24 V DC control circuit draws 130 mA peak during closing (with LUB12) and 60 mA sealed, making it compatible with standard 24 V DC control systems in industrial panels. Rated for 0.09 kW at 400...440 V AC (50/60 Hz), this unit is suited for small motor loads such as fans, pumps, or conveyors in light industrial applications. The plug-in front-face mounting allows quick installation or replacement on the TeSys U base without disturbing wiring — a practical advantage for panel builders and MRO teams minimizing downtime. ## Standards Compliance and Protection Characteristics The LUCBX6BLTQ carries approvals under EN 60947-6-2, IEC 60947-6-2, UL 60947-4-1 (with phase barrier), and CSA C22.2 No 60947-4-1 (with phase barrier). These standards certify its suitability for motor starter applications in North American and European installations. The thermal overload class is Class 10 (frequency 40...60 Hz, temperature compensation -25...70 °C) per IEC 60947-6-2 and UL 508, meaning it will trip within 10 seconds at 7.2× Ir — appropriate for standard motor starting duty. The tripping threshold is set at 14.2 × Ir ±20 %, providing short-circuit protection coordination with the upstream TeSys U power base. The unit also offers phase failure sensitivity and immunity to microbreaks up to 3 ms, ensuring nuisance tripping is minimized on supply disturbances common in industrial environments. ## Environmental and Mounting Specifications The control unit measures 45 mm wide, 66 mm high, and 60 mm deep, fitting the standard TeSys U modular footprint. The plug-in design (front face) allows the control unit to be swapped without removing the power base wiring — a time-saver during troubleshooting or upgrade cycles. Rated for operation up to 2000 m altitude, with vibration resistance of 2 gn (poles open) and 4 gn (poles closed) per IEC 60068-2-6, and shock resistance of 10 gn (poles open) and 15 gn (poles closed) per IEC 60068-2-27. The protective treatment is TH conforming to IEC 60068, indicating suitability for tropical/humid environments.","metaTitle":"Schneider Electric LUCBX6BLTQ TeSys U Advanced Control Unit,","metaDescription":"Advanced control unit for TeSys U motor starters. 24 V DC control, 0.09 kW at 400 V.
