TeSys U

All-in-one motor starters up to 38 A (18.5 kW / 400 V).

Part of TeSys

TeSys U is the most compact solution for motor starters. Enabling direct-on-line or reversing motor control, as well as drive protection, TeSys U provides as standard total coordination, up to 50 kA short-circuit currents under 400V (25 kA for 38 A rating).

Simple, efficient, modular and compact, the TeSys U motor starter adapts to a wide range of applications. It is one of the first intelligent starters capable of integrating motor control, control and changeover functions in a unit 45 mm wide. The device provides short circuit breaking capacity of 50 kA with perfect coordination.

  • Simple to Maintain: Modular, plug & play structure helps you to perform quick maintenance.

  • Easy to Install and Use: Only one power base for all control units up to 38 A.

  • Efficient : Safe up to 45% of the time for installation and wiring.

  • Flexible: Wire the starter completely in the workshop, define the motor on site with plugin of the control unit.

  • Compact: Save up to 57% of cabinet space, reversing starter only 45 mm wide.

  • Intelligent: Direct access to detailed information for every motor starter of your installation.

  • Safe: Mirror contact as standard.

  • Advanced: Advanced motor management.


  • TeSys U all-in-one motor starter is dedicated to direct on line (including reverser) motor control applications.

  • Thanks to the high compactness and outstanding flexibility, it can be well adapted to all types of machines.

  • The strong communication capabilities, high breaking capacity and total coordination makes it highly suitable for process application.
