TeSys U

An all-in-one motor starter up to 18.5 kW that combines thermal & magnetic protection, switching and contactor in a single product

Part of TeSys

TeSys U is the most compact motor starter. It covers main motor applications (direct on line, reversers, drive protection) from 0 to 18.5 kW (0 to 38 A) ensuring a breaking capacity of 50 kA @ Ie ≤ 32A or 25 kA @ Ie > 32A with total coordination (according to IEC 60947-6-2).

TeSys U
  • Features

    Only 45 mm wide, the TeSys U all-in-one motor starter delivers a compact device to protect and control motors for forward and reverse direction. It can provide different tripping class (class 10, class 20 or class 5 to 30). TeSys U can provide you:

    • Multiple choices for electronic coil:
      • 24 V AC
      • 24 V DC low consumption
      • 48…72 V DC / 48 V AC
      • 110..220 V DC / 110...240 V AC
    • Short-circuit protection:
      • Isc of 50 kA at 400 V up to 15 kW
      • Isc of 25 kA at 400 V up to 18,5 kW
    • Overload protection:
      • From 0.15 to 32 A, 6 setting ranges
      • Test button
    • Reverse starter in 45mm frame only
    • Different options with plug and play modules:
      • Thermal function management modules
      • Communication modules
      • Auxiliary contact add-on modules

    LUCM specific control unit up to 32A enables advanced and settable diagnosis and statistic functions:

    • Instantaneous current values
    • Logs of last 5 trips
    • Number of starters, number of trips and number of operating hours

    As well as protection function:

    • magnetic tripping value
    • phase unbalance level
    • class type
    • jam
    • under current
    • Alarm available for all protection


    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 base plate & 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.
