Tripping threshold at 14.2 x Ir ±20% gives real coordination headroom, and it covers AC-44, AC-41, and AC-43 utilisation categories — so resistive, motor, and severe motor loads are all on the manifest. Rated 15 kW at 400 V and 18.5 kW at 690 V, 50/60 Hz. Control circuit voltage is 110–240 V AC or 110–220 V DC. Heat dissipation through the LUB control circuit holds at 3 W sealed. The unit takes about 280 mA inrush, then drops to 25 mA sealed — a clean draw for a crowded panel. ## Compliance & protection features Carries UL 60947-4-1, CSA C22.2, IEC 60947-6-2, and EN 60947-6-2 with phase barriers. Fire resistance on live-supporting parts hits 960 °C (IEC 60695-2-12). Also includes phase failure sensitivity, earth fault protection, and immunity to microbreaks down to 3 ms. IP20 front panel and wired terminals (IP40 outside the connection zone). TH protective treatment per IEC 60068 for damp environments.","metaTitle":"Schneider Electric LUCD32FU TeSys Ultra Advanced Control Uni","metaDescription":"Active production.
