Square D LUB TeSys Ultra Power Base, 3-Pole Screw Clamp Control

Square D LUB TeSys Ultra Power Base, 3-Pole Screw Clamp Control

The Square D LUB TeSys Ultra power base is a standard 3-pole (3NO) power base rated up to 32A Ie / 690V Ue, designed to be completed with a Square D LUC control unit to form a complete TeSys U starter controller for 3-phase motor applications up to 15kW@400V. This power base is offered across motor full-load current (FLA) ratings from 12A to 32A, letting panel builders match the base to the motor circuit while sharing the same modular design, screw clamp control terminals, and rotary handle operation. Built with power contacts, a control coil, and a rotary handle, the LUB is suited to industrial and commercial panel-building applications requiring reliable, code-compliant motor control assemblies.

Key Features
