Schneider Electric LUCA05BL Non-Reversing Motor Starter

Schneider Electric LUCA05BL is a TeSys U standard control unit that forms a non-reversing, three‑phase motor starter when mounted in a compatible power base such as LUB12. It features a 24 V DC coil with a control current range of 1.25 A to 5 A and a Class 10 thermal rating for reliable duty in industrial panels. This 3‑pole unit is designed to be inserted into TeSys U power bases to deliver a motor control solution for three‑phase machines up to 12 A in the load circuit, with power ratings suitable for up to 600 V AC (regional variants list up to 690 V). The LUCA05BL is typically paired with LUB12 (and other LUB bases) to support motor applications around 10 HP at 600 V, making it a compact, field-adjustable control element for conveyors, pumps, fans, and similar equipment. In use, it acts as the control interface between the 24 V DC control circuit and the higher‑voltage motor circuit, while the power base provides overload protection and interlocking, enabling a simple, robust non‑reversing starter for 3‑phase motors.
