Rated in utilization category AC-43, it handles 18.5 kW at 400…440 V AC, 18.5 kW at 500 V, and 22 kW at 690 V AC — the AC-43 rating means it is tested for the higher switching frequency and current stresses typical of drive-fed motors, where the waveform is not a clean sine wave. Control circuit voltage is 110…240 V AC or 110…220 V DC, with a drop-out threshold of 55 V for either supply. Closing current peaks at 280 mA; sealed holding current drops to 25 mA rms — the coil draw is low enough that a standard PLC relay output can drive it, but verify the inrush if the output is a solid-state relay with a minimum load specification. The tripping threshold is 14.2 x Ir ±20 % — this is a magnetic-only instantaneous trip, not a thermal overload. It clears a bolted fault fast but provides no overload protection; that is why it pairs with a separate overload relay or the drive's own thermal model. IP20 on the front panel and wired terminals, IP40 on the front panel outside the connection zone. Compliant 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 between control/auxiliary circuits and the main circuit is maintained at 400 V SELV. Mounts via plug-in front face — it clips onto a compatible TeSys Ultra base or directly onto the contactor assembly. Dimensions are 45 mm wide, 66 mm high, 60 mm deep. Operating time is 35 ms opening and 50 ms closing when paired with a LUB38 control unit.","metaTitle":"Schneider Electric LUCL38FU TeSys Ultra Magnetic Control Uni","metaDescription":"Schneider Electric LUCL38FU TeSys Ultra magnetic control unit.
