The Schneider Electric LUB12 is a non-reversing motor starter power base from the TeSys U (TeSys Ultra) series, designed for direct-on-line starting and control of three-phase motors up to 12 A. This modular, self-protected power base integrates a built-in circuit breaker and contactor to provide total coordination and motor protection. It features screw clamp connections and a compact 45 mm wide design suitable for both DIN rail and panel mounting. The unit includes 1 normally open and 1 normally closed auxiliary contact and is designed to work with plug-in control units for solid-state overload protection. Ideal for industrial motor control applications including pumps, fans, conveyors, and compact OEM machinery, the LUB12 offers robust protection with IP20/IP40 ratings and operates across a wide voltage range up to 690 V AC.
