Manual reset, tripping threshold set at 14.2 × Ir — so short-circuit protection scales with the overload setting. Motor power: 7.5 kW at 400 V, 9 kW at 500 V, 15 kW at 690 V. Coil draws 220 mA inrush, 80 mA sealed, 24 V DC. Opens in 35 ms, closes in 70 ms with LUB32 or LUB38 control circuit. Rated AC-44/AC-41/AC-43 — handles mixed motor and resistive loads. Phase failure protection built in. IP20 front, IP40 above panel. No separate base needed; front-face plugs into the TeSys Ultra contactor. ## Sourcing reality LUCB18BL is current production. Order via RFQ for lead times and pricing. Plug-in mount onto the contactor frame — no extra screw or snap track. Vertically oriented; allow 60 mm behind the panel (depth). Ambient -25 to 70 °C with class 10 overload curve. Altitude 2000 m derating starts above that. Operating altitude: 2000 m. Vibration 4 gn closed contacts, 2 gn open. Shock 15 gn closed, 10 gn open. IP20 wired terminals means no extra finger duct needed inside the panel. Listed under EN 60947-6-2, IEC 60947-6-2, UL 60947-4-1 (with phase barrier), CSA C22.2 No 60947-4-1 (with phase barrier). TH protective treatment per IEC 60068. Fire resistance 960 °C on live-part supports. Safe separation 400 V SELV between control/auxiliary and main circuits. No separate RFQ for UL/CSA marks — they’re factory-stamped.","metaTitle":"Schneider LUCB18BL TeSys Ultra Motor Control, 24V","metaDescription":"Current-production LUCB18BL TeSys Ultra control unit. 24 V DC, manual reset, class 10 overload, 14.2xIr short-circuit trip.
