LU2B12BL reversing starter base: control-unit pairing and motor-direction checks
Schneider Electric LU2B12BL is a TeSys U reversing power base for three-phase motor starting. It is not a complete protected starter without the matched control unit and required assembly. The shared motor-control collage is a family illustration, not an exact product image of LU2B12BL.

Build the complete starter
Identify the installed LUC control unit, auxiliary modules and reversing arrangement before selecting LU2B12BL. Confirm motor current, supply voltage and the required overload and short-circuit coordination. The power base alone should not be described as providing every protection feature of the assembled starter.
Direction and interlocks
Map forward and reverse commands, electrical interlocks and the 24 V DC reverser supply. When replacing LU2B12BL, preserve wire identification and the original direction sequence. Check the actual motor rotation at a controlled first start to prevent process damage.
Mechanical and lifecycle fit
Inspect rail or screw mounting, terminal access, handle operation and enclosure space. Schneider has lifecycle notices for this code in some regions, so confirm supply or an approved alternative with the complete starter configuration. Do not replace LU2B12BL on appearance alone.

Before placing an order
Quote LU2B12BL together with the LUC unit, motor data and reverser wiring details. An alternate TeSys U base for LU2B12BL must be evaluated as an assembled system.
For LU2B12BL, confirm the printed designation, current Schneider Electric documentation, installation conditions and any lifecycle notice before purchase or commissioning.
