LUB12 SCHNEIDER Power base, TeSys U, 3P, 12A/690V
The Schneider Electric LUB12 is a non-reversing power base from the TeSys U modular motor starter range. Rated for 3-pole applications up to 12 A and 690 V, it serves as the foundational power module that integrates switching and isolation functions. It operates by combining with plug-in control units (such as the LUCA, LUCB, or LUCC series) and optional function modules to build a complete, compact motor starter for direct-on-line (DOL) motor control applications.
