Rated operational voltage is 690 V AC with insulation rated at 690 V per IEC 60947-6-2 and 600 V per UL 60947-4-1. The utilisation category AC-43 confirms it handles motor loads with occasional overloads — typical for a reversing or plugging duty cycle. Control circuit is 24 V DC, drawing 220 mA during closing and 80 mA sealed with the LUB38 control module. Drop-out voltage is 14.5 V, so the coil releases cleanly on a sagging bus. Mounts via plug-in front face to a TeSys Ultra base — no DIN-rail bracket needed, but the base itself snaps onto a 35 mm rail. Panel cut-out and wiring access follow the IP20 front panel rating; other faces are IP20 as well, with the front connection zone rated IP40. ## Protection and coordination The LUCL38BL integrates short-circuit protection and manual reset, with a tripping threshold of 14.2 x Ir ±20 %. That magnetic trip level clears hard faults fast — 35 ms opening with the LUB38 control module — while the thermal curve handles overloads. Designed specifically for protecting variable-speed drives and soft starters, not just across-the-line motor starts. The immunity to microbreaks (3 ms) and voltage dips (70 % for 500 ms) keeps the unit from nuisance-tripping on a weak grid. Safe separation of circuits: 400 V SELV between control/auxiliary and main circuits per IEC 60947-1. That simplifies panel wiring — control and power can share a trough without extra insulation barriers. ## Compliance and environment The LUCL38BL carries UL 60947-4-1 and CSA C22.2 No 60947-4-1 listings (with phase barrier), plus EN/IEC 60947-6-2. The TH protective treatment per IEC 60068 covers tropical environments — no extra conformal coating needed for humidity. Fire resistance: 960 °C on live-part supports per IEC 60695-2-12, 650 °C on other parts. Shock and vibration ratings (10 gn open, 15 gn closed; 2 gn open, 4 gn closed) cover most industrial machinery without derating.","metaTitle":"Schneider Electric LUCL38BL TeSys Ultra Magnetic Control Uni","metaDescription":"Schneider Electric LUCL38BL TeSys Ultra magnetic control unit for 3-phase motor protection. 18.5 kW at 400 V AC, 24 V DC coil, IP20 front.
