Schneider Electric LUCA05FU is a standard TeSys U control unit designed to be installed in power bases LUB12, LUB32, or LUB38 to form a TeSys U starter controller for 3‑phase motors. It supports a coil voltage of 110–240 V AC/DC and a current range of 1.25–5 A, with thermal‑magnetic protection classified as class 10 for short‑circuit protection. When paired with the LUB12 base, the assembly covers motor applications up to 5.5 kW at 400 V, and LUCA05FU provides an opening time of about 35 ms with the LUB12 control circuit.
