Schneider are in the process of amending the colour of the TeSys range, from White to Black. This means that the stock you receive could be either of these colours. Please be assured that the colour change in no way affects the Fit, Form or Function of the product.

Build a starter system for your three-phase motor with the help of this advanced control unit from Schneider Electric. It includes thermal protection and an overload alarm, so you can protect equipment and diagnose faults. The unit also offers phase failure and imbalance safeguards to prevent motor damage. An adjustable current setting range between 8 and 32A means you can set your protection level to match your motor rating. As it plugs straight into LUB power bases, it's easy to boost your controls.

This starter's designed for use with AC-43 and AC-44 motors, so it can be used to operate squirrel-cage motors.

Yes. A TH treatment is applied to the unit, meaning it's well-suited to hot and humid environments and able to work at temperatures between -25°C and +70°C.

The TeSys U is a modular system for motor control; it enables the user to create a customised solution for their control requirements, from a series of standard modules. The plug-in modules allow the assembly and wiring before the selection of motor protection parameters and control voltages, they can be created or changed in seconds by changing the plug-in modules. A host of DOL starting applications can be catered for.

First choose a Power Base- 12A or 32A, direct on line or reversing. The power base includes 2 auxiliary contacts.
Then choose the plug-in protection module by motor full load current and control voltage required.
Additional plug in functions can be selected and added at any time.
The plug-in bases can use any LU9 type blocks see stock no. 493-8779 for base option
