Schneider Electric LUCA32FU Overload Relay 8-32A

LUCA32FU is Schneider Electric’s TeSys Ultra standard control unit for motor protection, rated 8–32 A with a 110–240 V AC/DC coil, designed to provide reliable overload and short-circuit protection for 3‑phase motors (single‑phase loads are supported in appropriate configurations). It uses class 10 thermal‑magnetic protection and offers an adjustable overload protection dial, enabling precise setting to match motor inrush and running current while protecting the circuit. The control unit includes its own electronic protection components and a current adjustment dial, and its modular, plug‑and‑play construction makes installation, testing, and maintenance straightforward within a TeSys LUCA installation. Schneider Electric positions LUCA32FU as part of its advanced motor management system, granting direct access to detailed information for every motor starter in the installation and helping technicians diagnose, configure, and synchronize protection settings across multiple devices in a panel. This makes it suitable for industrial control panels, conveyor systems, pumps, fans, and other equipment relying on robust, maintainable motor protection from a single, integrated device.
