Schneider Electric LUCB12FU Advanced Control Unit

Schneider Electric's LUCB12FU is an advanced control unit in the TeSys Ultra family that pairs with the LUB12 power base to form a compact motor starter for three‑phase machines. It handles motor current in the 3–12 A range and supports both single‑ and three‑phase loads, with a 110–240 V coil (AC or DC) to suit diverse control circuits. The LUCB12FU provides integrated protection and diagnostics and is specified for TeSys Ultra class 10 protection with modular, plug‑and‑play architecture for quick maintenance. When combined with the LUB12 base (a 12 A, 3‑pole power base rated up to 690 V), it enables a complete starter for motor control up to 12 A per branch. Thermal overload protection is user‑adjustable across multiple setpoint ranges (including 0.15–0.6 A, 0.35–1.4 A, 1.25–5 A, 3–12 A, 4.5–18 A, 8–32 A, and 9.5–38 A), aligning protection with the connected motor rating and configuration. This arrangement delivers robust motor management with clear status signaling and a serviceable design for industrial panels that require reliable TeSys Ultra control and protection for three‑phase or single‑phase loads.
