Schneider Electric LUCA05FU Motor Starter Protector

Schneider Electric LUCA05FU TeSys U standard control unit is a motor starter protector designed for small three‑phase motors. Supplied as a NEMA Size 1 controller (WL48-3), it covers current settings from 1.25 A to 5 A with a built‑in current adjustment dial and provides overload and short‑circuit protection. The coil operates on 110–240 V AC/DC, and the unit is designed for plug‑in installation in power bases such as LUB12, LUB32, and LUB38 to form a complete TeSys U starter controller. With class 10 thermal‑magnetic protection, LUCA05FU is suitable for motor applications up to about 1.5 kW at 400 V (3‑phase), making it a compact option for protections in conveyors, fans, pumps, and small machine tools.
