Schneider Electric LUB12 Motor Starter Power Base

Schneider Electric LUB12 is a non-reversing, 3‑pole motor starter power base in the TeSys U/Ultra family, designed to be paired with a TeSys U control unit to form a complete starter for three‑phase motors. It is rated for up to 12 A and up to 690 V AC, with a 3P configuration and 1NO + 1NC contact arrangement, making it suitable for direct‑on‑line starting in industrial applications. The base uses screw‑clamp terminals and a modular, plug‑and‑play architecture to enable quick maintenance and straightforward interconnection with LUC control units. In practice, the LUB12 provides a compact foundation for scalable motor control, pairing with TeSys U controllers to support reliable, field‑upgradable motor starters in manufacturing and processing environments.
