The LUCL32ES handles that. It is rated for AC-44, AC-43, and AC-41 utilisation categories — AC-44 being the toughest (frequent plugging and inching of slip-ring motors). Motor power capability reaches 15 kW at 400-440 V AC, 15 kW at 500 V AC, and 18.5 kW at 690 V AC. Control voltage is 48 V AC or 48-72 V DC, with a typical inrush of 280 mA and a sealed hold of 45 mA. The unit mounts plug-in to the front face of the TeSys Ultra contactor base — no DIN-rail space consumed beyond the contactor itself. IP20 on the front panel and wired terminals, IP40 on the front face outside the connection zone. Rated insulation voltage is 690 V per IEC 60947-6-2, 600 V per UL 60947-4-1 and CSA C22.2 No 60947-4-1. The 3 ms immunity to microbreaks means the unit ignores a supply dip of up to 3 ms, which is common on a line with contactor bounce or a brief loss of control power. The 70% / 500 ms immunity to voltage dips (per IEC 61000-4-11) means the control circuit holds in during a sag that would drop out a less tolerant coil. For a commissioning engineer: the opening time is 35 ms with either the LUB32 or LUB38 control-circuit module; closing time is 60 ms with either. That is consistent timing across the range — no surprise when coordinating with upstream protection. The LUCL32ES carries compliance to EN/IEC 60947-6-2 (the transfer-switch standard that covers motor-protective switching devices), 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/auxiliary and main circuits per IEC 60947-1. Fire resistance is 960 °C on parts supporting live components, 650 °C on other parts per IEC 60695-2-12. Protective treatment is TH per IEC 60068 (tropical heat and humidity). Operating altitude is 2000 m without derating.","metaTitle":"Schneider Electric LUCL32ES TeSys Ultra Magnetic Control Uni","metaDescription":"Schneider Electric LUCL32ES TeSys Ultra magnetic control unit for 3-phase motor protection.
