It covers overload, short-circuit, phase imbalance, phase failure, and earth faults in one package. Rated motor power is 0.09 kW at 400...440 V AC 50/60 Hz, so it sits at the small end of the TeSys Ultra line. If you're sourcing for a light-duty motor, this is the control unit that fits. ## Key ratings – the ones that matter for fit Tripping threshold: 14.2 x Ir ±20% – a fixed trip curve, not adjustable. That's for short-circuit protection. Thermal overload class 10, rated for Class 10 protection across -25°C to 70°C per IEC and UL 508. Control voltage is 110...240 V AC or 110...220 V DC, drawing 280 mA max during closing and 35 mA sealed. Dimensions: 2.4 in deep × 1.8 in wide × 2.6 in tall – a small plug-in unit on the front face. IP20 front panel and wired terminals; IP40 front panel outside connection zone.","metaTitle":"Schneider LUCBX6FU TeSys Ultra Control Unit, Manual Reset","metaDescription":"Schneider LUCBX6FU TeSys Ultra advanced control unit.
