Product details

TeSys Ultra Control Unit

The LUCDX6FU is a Schneider TeSys Ultra advanced control unit for motor protection, rated for 110…240 V AC or 110…220 V DC control circuits and offering manual reset, plug-in mounting on a front face, and IP20 protection on the front panel and wired terminals. 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.
