LUCA12FU TeSys U Standard Control Unit Schneider Electric
The Schneider Electric LUCA12FU is an advanced TeSys U standard control unit designed for plug-in integration into TeSys U power bases (LUB12, LUB32). Covering a wide thermal adjustment setting of 3 to 12 A, it provides essential 3-phase motor protection, including thermal-magnetic protection, phase failure detection, and short-circuit protection. Operating on a universal coil supply voltage of 110 to 240 V AC/DC, this Class 10 control unit offers a compact, modular starter solution ideal for direct-on-line (DOL) motor starting, reversing, and protection in automated control panels.
