Rated operational voltage is 690 V AC with insulation voltage at 690 V conforming to IEC 60947-6-2 and 600 V per UL 60947-4-1. The unit carries motor power ratings of 7.5 kW at 400...440 V AC, 9 kW at 500 V AC, and 15 kW at 690 V AC, all at 50/60 Hz. Control circuit voltage is 24 V AC, drawing 220 mA during closing and 90 mA sealed. The utilisation categories AC-41, AC-43, and AC-44 define the switching duty. AC-41 covers resistive loads, AC-43 covers motor starting and switching, and AC-44 covers motor switching with inrush currents. The tripping threshold is set at 14.2 x Ir ±20%, meaning the unit trips at 14.2 times the set current rating, providing short-circuit protection for motor circuits. Operating time is 35 ms opening and 70 ms closing with LUB32 or LUB38 control circuit modules. The 3 ms immunity to microbreaks means the unit tolerates brief power interruptions without nuisance tripping, critical for motor control reliability. Voltage dip immunity at 70% for 500 ms per IEC 61000-4-11 ensures ride-through during sags. IP20 protection on the front panel and wired terminals per IEC 60947-1, with IP40 on the front panel outside the connection zone. The plug-in front face fixing means the unit clips into a base or mounting plate without tools, simplifying replacement. Heat dissipation is 3 W for the control circuit with either LUB32 or LUB38 modules. Operating altitude is 2000 m; derate above that. The self-cooled design requires no external ventilation for the motor load path. The LUCL18B complies with 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 circuits is rated at 400 V SELV between control and auxiliary circuits, and between control/auxiliary and main circuits per IEC 60947-1. Fire resistance is 960 °C for parts supporting live components per IEC 60695-2-12, and 650 °C for other parts. Protective treatment is TH conforming to IEC 60068 for tropical environments. Shock resistance: 10 gn with power poles open, 15 gn with poles closed per IEC 60068-2-27. Vibration resistance: 2 gn at 5...300 Hz with poles open, 4 gn with poles closed per IEC 60068-2-6.","metaTitle":"Schneider Electric LUCL18B TeSys Ultra Magnetic Control Unit","metaDescription":"Schneider Electric LUCL18B TeSys Ultra magnetic control unit for 3-phase motor protection.
