Schneider Electric LUCA05FU Solid State Relay

Schneider Electric LUCA05FU is a TeSys U standard control unit that provides integrated solid-state overload protection and a built-in control power source for three-phase motors. It covers a load current range of 1.25 A to 5 A and accepts a coil supply of 110–240 V AC/DC, with Class 10 protection for fast, reliable response in motor circuits. As part of the TeSys U family, LUCA05FU is designed to pair with TeSys U contactors and motor-protection assemblies, delivering a compact, integrated solution that reduces panel wiring by combining overload protection and control power in a single unit. Typical applications include starting and protecting 3-phase motors in industrial automation—conveyors, manufacturing lines, and packaging equipment—where reliable overload protection and streamlined installation are essential. The unit’s solid-state overload relay and built-in control power source are key features that support safe, efficient motor control across 110–240 V AC/DC control schemes.
