The classic for motor start controls for medium capacities

The star-delta controls with integrated motor guard is best suited for starting mediuim capacity motors (4..30kW).  The soft starter motor controls (soft start motor starter controls) with various motor guards and monitoring functions are best suited for starting medium and large motors (4..100kW).  The large selection of options makes the controls very versatile. The controls can be used for agitators, ventilators, conveyor belts, pups, feed mixers, float controls etc.
The controls are standard equipped with 2 wireless and one Klixon connector. A Start-Hand-0-Remote switch allows for simple operation and via a reset button on the front of the casing one can reverse the motor guard if necessary. The standard controls support motor capacities from 5.5 to 18.5kW.  The nominal voltage is always activated and only through changing the thermal element can the controls be adapted to a different capacity. This allows you to reduce your stock.

The star-delta controls are available in various versions. They are ideal for controlling agitators, slurry pumps, water pumps, mixers, conveyor belts etc.

We offer the following standard versions:

  • Star-delta 5.5 – 22kW
  • Star-delta 5.5 – 22kW with integrated slider controls (slurry/water reswitching)
  • Star-delta 5.5 – 22kW with integrated electrocylinder controls (reflux On/Off)
  • Star-delta 5.5 – 22kW with integrated slider and electrocylinder controls
  • Star-delta 5.5 – 22kW with turning function for suction/pumps

All controls have a main power switch, a Start-Hand-0-Remote switch and a thermal element reset button. In addition, wireless and  Klixon connectors are standard.

We can implement further client wishes quickly, efficiently and cost-effectively.
