The Speed Starter is the new device class between motor starters and frequency converters with a particularly intuitive operation. This compact solution provides all of the functions necessary for different speeds, soft start, and safe stopping with the Safe Torque Off (STO) function. The Speed Starter (CONTACTRON Speed Starter) features simple operation with various speeds, from normal speed, creeping speed, and soft start, all the way to energy efficiency and ramping functions.

The CONTACTRON Speed Starter is now also available for motors up to 7.5 kW. Benefit from the intuitive setup of the variably adjustable ramps and up to four fixed speeds. The analog input and integrated STO function provide flexibility and safety.
The CONTACTRON Speed Starters are available in a wide range of versions:
Select the appropriate product for your application.
Benefit from flexible application options with an extended power range from 0.25 kW to 7.5 kW. In addition to protecting against accidental changes to the device, the CONTACTRON Speed Starter can be protected with an individually definable code. Select the appropriate product for your application.
Easy wiring and intuitive operating concept: The plug-and-play solution enables easy startup. You can set the required parameters quickly and efficiently via the position selector switch/rotary switch. CONTACTRON Speed Starter – the intuitive solution for a variety of motor applications with different speeds.
With the integrated Safe Torque Off (STO) function, the CONTACTRON Speed Starter is unique in its device class. This means that you benefit from two-channel, safe shutdown without complex procedures and without additional contactors. SIL 3 and PLe certifications provide for your safety.
In a compact design with an overall width starting at just 35 mm, the CONTACTRON Speed Starter is currently the narrowest device in its class available on the market. Higher density in the control cabinet will save you additional costs.
The speed starter has all the basic functions of CONTACTRON motor starters that you need: start, reverse rotation, overload protection, and safe shutdown of three-phase asynchronous motors. You can realize up to four fixed speeds as well as the soft start and stop of the motor at full torque. With the analog input, you can set the speed to a variable value and also define a minimum and maximum frequency for your application.
