Schneider Electric LUCA12BL Motor Starter Control Unit

Schneider Electric LUCA12BL is a TeSys Ultra standard control unit that slots into TeSys power bases (LUB12, LUB32, LUB38) to form a complete motor starter controller for three‑phase motors. It handles a 3 A to 12 A load current with a 24 V DC coil and includes built‑in class 10 thermal‑magnetic protection for overload and short‑circuit events. This unit is designed for 3‑phase motor applications up to 5.5 kW at 400 V, depending on the base and motor configuration, making it suitable for panel‑mounted starters in industrial environments. The LUCA12BL is a core component of Schneider Electric’s TeSys U/Ultra motor control ecosystem, enabling straightforward integration with other TeSys U devices to provide reliable starting, protection, and control in motor circuits.
