Star-Delta

The NOLTA star-delta easy start for heavy applications, e.g.:

  • Rolling mills
  • Move mills
  • Waste water pumps

All NOLTA star-delta starters are equipped with a rotary selection switch with thermal and under voltage release as well as a connections motor thermal sensor.
The under-voltage coil runs on 230V, therefore the installation requires a neutral line. The starters are equipped as standard with a carrying handle and an input lead with CEE 32 A phase inverter 3P+E+N, 6h, 400 V.
