Schneider Electric LUB12 Power Base

The Schneider Electric LUB12 is a TeSys U standard power base rated at 12 A and 690 V for three-phase motor circuits up to 5.5 kW at 400 V. It provides the power contacts, control coil and rotary handle in a 45 mm wide housing that mounts on DIN rail or by screws. The unit must be paired with a LUC control unit to create a complete starter controller with overload protection.

Suits panels needing a compact non-reversing

This base suits installers building non-reversing starters up to 12 A who want high breaking capacity (50 kA at 400 V) and start-stop rates of 3600 cycles per hour. It is not for applications requiring an integrated reversing function or a self-contained starter without a separate LUC control module. Buyers needing a wider current range or built-in protection should look at other TeSys U configurations.

45 mm width and 12 A rating decide fit

The 45 mm width determines DIN-rail spacing and enclosure layout, while the 12 A rating sets the maximum motor load the base can switch. Both values are fixed by the hardware and cannot be changed by the control unit, so verify panel space and motor full-load current before ordering.
