It mounts via a plug-in front face, occupying a 1.8 in wide × 2.6 in high cutout with a 2.4 in depth – standard TeSys Ultra footprint for panel layouts. Control circuit voltage spans 110–240 V AC and 110–220 V DC, covering common global panel supplies. Typical current consumption is 280 mA during closing and 25–35 mA sealed, depending on the control unit variant. Motor power ratings: 1.5 kW at 400–440 V AC, 2.2 kW at 500 V AC, and 3 kW at 690 V AC, 50/60 Hz. The unit provides protection against overload, short-circuit, earth fault, phase failure, and phase imbalance. ## Key ratings and their meaning for fit Utilisation categories confirm the unit is rated for motor switching with resistive, mixed, and motor loads. Thermal overload class 10 per IEC 60947-6-2 and UL 508 – covers motor starting conditions. Tripping threshold 14.2 × Ir ±20% on short-circuit protection, and immunity to micro-breaks up to 3 ms, ensures ride-through on line dips without false trips. IP20 front panel and wired terminals, IP40 front panel outside connection zone – fine for control cabinet installation with no additional gasketing. ## Compliance and certification Certified to EN 60947-6-2, IEC 60947-6-2, UL 60947-4-1 with phase barrier, and CSA C22.2 No 60947-4-1 with phase barrier. Safe separation of control and auxiliary circuits at 400 V SELV per IEC 60947-1. Fire resistance: 960 °C on parts supporting live components per IEC 60695-2-12, and 650 °C general. Protection treatment TH per IEC 60068 for damp heat.","metaTitle":"LUCB05FU TeSys Ultra Control Unit, 110–240 V AC","metaDescription":"LUCB05FU advanced control unit for motor protection, rated 1.5 kW at 400 V AC.
