It mounts via a plug-in front face onto a compatible TeSys Ultra base, integrating into a DIN-rail panel layout. Rated for 7.5 kW at 400...440 V AC 50/60 Hz, 9 kW at 500 V AC, and 15 kW at 690 V AC. The control circuit operates on 48 V AC or 48...72 V DC. Compliance with EN/IEC 60947-6-2, UL 60947-4-1, and CSA C22.2 No 60947-4-1 (with phase barrier) means it meets the standards for motor-starter and controller combinations in North American and European panels. The IP20 front-panel protection keeps live terminals behind the enclosure door. The utilisation categories AC-41 (resistive), AC-43 (motor starting, plugging, inching), and AC-44 (motor switching, frequent starts) define the load type this unit can switch. AC-43 and AC-44 are the relevant ones for motor duty — the unit is rated for the higher stress of frequent starting and reversing, not just steady-state running. The tripping threshold is 14.2 x Ir +/- 20%. Opening time is 35 ms; closing time is 60 ms. Rated insulation voltage (Ui) is 690 V per IEC 60947-6-2, 600 V per UL/CSA. Safe separation of circuits is maintained at 400 V SELV between control/auxiliary and main circuits. ## Integration notes The plug-in front-face design means the control unit can be swapped without disturbing the power wiring on the base, reducing downtime during a replacement. Heat dissipation is 3 W for the control circuit with either LUB32 or LUB38 coil — negligible for panel thermal budgeting. The unit is self-cooled (no external fan required), and the operating altitude is rated to 2000 m without derating. Vibration resistance is 2 gn (poles open) and 4 gn (poles closed) across 5...300 Hz per IEC 60068-2-6. Shock resistance is 10 gn (poles open) and 15 gn (poles closed) per IEC 60068-2-27. These ratings confirm it holds up on a machine-mounted panel subject to normal industrial vibration.","metaTitle":"Schneider TeSys Ultra LUCL18ES Magnetic Control Unit","metaDescription":"Schneider Electric TeSys Ultra LUCL18ES magnetic control unit, 7.5 kW at 400 V AC, 48 V AC / 48-72 V DC coil.
