Schneider Electric LUCA05FU Motor Starter Control Unit

Schneider Electric LUCA05FU is a standard control unit for TeSys Ultra motor starters, rated for 1.25–5 A loads and suitable for 2–10 HP motors, with class 10 thermal protection and a control voltage of 110–220 V AC/DC. This compact, modular device includes built‑in electronic overload protection and a current‑adjustment dial, enabling precise protection without external relays. It is designed to be integrated into TeSys U starter assemblies and, when paired with the appropriate power bases (for example LUB12, LUB32, LUB38), forms a complete motor starter controller for three‑phase applications; the unit also supports single‑phase motors in certain configurations. The LUCA05FU provides multiple overload protection bands—0.15–0.6 A, 0.35–1.4 A, 1.25–5 A, 3–12 A, 4.5–18 A, and 8–32 A—allowing tailored protection to motor size, and it emphasizes rapid maintenance through its modular, plug‑and‑play design and direct access to device information for installers. This TeSys LUCA family component is RoHS compliant, reflecting Schneider Electric’s commitment to restricting hazardous substances, and is aimed at dependable motor control with straightforward servicing within industrial control panels.
