The safe, simple, and efficient operation of three-phase asynchronous motors is an important objective in a large number of applications. The Contactron Speed Starter from Phoenix Contact is the new device class that bridges the gap between motor starters and frequency converters with easy operation.
The operator interface consists of a rotary switch and three buttons with a display, so all settings can be made intuitively. This compact and cost-effective solution provides all of the functions necessary for different speeds. These include normal speed, creeping speed, soft start, energy efficiency and ramp functions, and even safe stopping with the Safe Torque Off function.
