DOL panels are simple and relatively cheap but lacks the advantages of an inverter or variable speed drive. For example, the Schneider ATV310 comes with the following motor protection built-in:

  • Motor overload/overcurrent
  • Motor short circuit
  • Output phase loss (cable disconnected)
  • Input phase loss
  • Ground short circuit
  • and many more…

An inverter or variable speed drives also greatly reduces the inrush current or current spike and this is important if frequent start/stops are required. Inrush current can contribute to increased energy consumption from a typical motor.
