The unit is self-cooled and plugs into the front face of a TeSys U power base, so the entire starter assembly (control unit + power base + optional communication module) occupies a single 45 mm wide slot on the DIN rail. That 45 mm width is the same across the TeSys U family, meaning a panel layout planned around one control unit accepts any other without re-spacing the rail. Rated motor power is 1.5 kW at 400...440 V AC, 2.2 kW at 500 V AC, and 3 kW at 690 V AC — all at 50/60 Hz. The utilisation categories cover AC-41 (resistive), AC-43 (motor starting), and AC-44 (plugging / inching), so the unit is rated for the full range of motor duty, not just across-the-line starting. ## Control voltage and wiring constraints Control circuit voltage is 110...240 V AC or 110...220 V DC, with a sealed current draw of 25 to 35 mA depending on the LUB power base variant. Inrush at closing hits 280 mA. The drop-out voltage is 55 V for both AC and DC circuits — below that the unit releases, so a sag to 55 V on a 110 V nominal line drops the starter. Immunity to voltage dips is 70 % for 500 ms per IEC 61000-4-11, meaning the control unit rides through a 30 % sag for half a second without dropping out. Safe separation between control and main circuits is maintained at 400 V SELV per IEC 60947-1, so the control wiring can be treated as a separated extra-low-voltage circuit relative to the power poles. The front panel carries IP20 protection; the area outside the connection zone is IP40. That is typical for a panel-mounted device — no special sealing needed inside a standard IP54 enclosure. ## Standards and approvals — what they certify The LUCA05FUTQ carries IEC 60947-6-2, EN 60947-6-2, UL 60947-4-1, and CSA C22.2 No 60947-4-1 — the full suite for motor starters and controller-devices. The UL/CSA listing is with a phase barrier, which is a standard requirement for multi-motor panels in North American installations.","metaTitle":"Schneider TeSys U LUCA05FUTQ Standard Control Unit, 1.5 kW a","metaDescription":"LUCA05FUTQ TeSys U standard control unit for 3-phase motor protection.
