Schneider Electric LUCA12BL Standard Control Unit

Schneider Electric LUCA12BL is a TeSys Ultra standard control unit designed for 3‑phase motor control with a 24 VDC coil, rated for 3 to 12 A per load. When inserted into TeSys U power bases such as LUB12, LUB32, or LUB38, it forms a compact three‑phase starter controller suitable for motors up to about 5.5 kW at 400 V. The unit provides overload and short‑circuit protection, includes essential electronic components, and features a current adjustment dial for precise setting, all within a modular, plug‑and‑play design that facilitates quick maintenance. It offers Class 10 protection and direct access to detailed information for every motor starter in an installation, supporting scalable motor management across multiple machines. Common applications include conveyors, pumps, and fans in industrial automation where robust motor protection and straightforward service are important, and the 24 VDC coil variant is commonly used in control cabinets and automation panels requiring reliable control of three‑phase motors.
