Schneider Electric LUCB12BL PLC Advanced Control Unit

Schneider Electric LUCB12BL Advanced Control Unit is the TeSys U control module that sits in TeSys U starter configurations to provide motor protection and diagnostics for three‑phase motors. It accepts a 24 V DC coil and supports 3–12 A for three‑phase loads, making it suitable for small to mid‑size motor applications. The LUCB12BL includes built‑in protection and diagnostics as part of Schneider Electric's TeSys U family and is designed to be inserted into TeSys U power bases such as LUB120, LUB320, and LUB380 to form a complete starter controller. It is class 10 rated and uses a modular plug‑and‑play architecture that supports rapid maintenance and scalability in multi‑motor systems.
