Product

The DFE is Fairford's internally bypassed, non-optimising Soft Starter which is perfect for panel builders and end users alike. To the user it offers competitive pricing, soft stopping and the removal of high transient currents.

To the panel builder it can easily substitute a Star/Delta starter because it fits into a similar footprint thus simplifying installation.
