It provides protection against overload, short-circuit, phase failure, imbalance, and earth fault, with a tripping threshold of 14.2 x Ir ±20 % and Class 20 thermal overload capability per IEC 60947-6-2. ## Compliance Package The LUCDX6FU carries approvals under 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), covering the major global motor-protection frameworks. The control circuit provides safe separation at 400 V SELV per IEC 60947-1. Heat dissipation runs 2 W with LUB12 control circuit, 3 W with LUB32 or LUB38—factor this into panel thermal budget. Plug-in mounts to the front face. Operating time: 35 ms opening, 50 ms closing. Vibration rated 2 gn (poles open) / 4 gn (poles closed) over 5–300 Hz. Shock rated 10 gn (poles open) / 15 gn (poles closed). TH protective treatment per IEC 60068 for humid environments.","metaTitle":"Schneider TeSys Ultra LUCDX6FU Control Unit, Active Producti","metaDescription":"Schneider TeSys Ultra LUCDX6FU control unit for motor protection. 110-240V AC/DC, manual reset, IP20.
