Schneider Electric LUB12 Power Base

Schneider Electric LUB12 is a 3-pole power base for TeSys U motor starters, rated for 12 A in free-air and compatible with up to 690 V, enabling single-direction rotation control. The base provides the electro-mechanical core of a TeSys U combination starter and features a modular, plug‑and‑play design that simplifies maintenance and future upgrades with additional control units and accessories. Wiring is accomplished with screw-clamp terminals for secure, vibration-resistant connections, and the unit is designed for quick assembly as part of a larger motor-control system. As part of Schneider Electric's TeSys U family of power bases, the LUB12 sits alongside higher-current variants such as LUB32, LUB38, LUB120, LUB320, and LUB380 to cover a range of motor sizes and configurations. The product is intended for applications requiring reliable, compact motor-switching in industrial environments and is commonly used as the foundational base in single-direction motor-control solutions where a modular, serviceable base is essential.
