About the Danfoss VLT 8452 380-480 V

The Danfoss VLT 8452 is a 315 kW frequency converter from the VLT 8000 AQUA series for 3 x 380-480 V supplies. Danfoss's VLT 8000 AQUA design guide gives it an output current of 600 A at 380-440 V; the full electrical data from the design guide is listed below. Danfoss's product page states that the VLT 8000 has reached the Inactive phase of its lifecycle, meaning it is discontinued and no longer in production, and names iC7-Aqua as its successor.

What is the VLT 8452 380-480 V used for?

Before you order

What to photograph or confirm so the right unit is quoted.

Read the full type code on the drive's label (it starts VLT8452, followed by the voltage, enclosure, filter, display and option codes) and send it complete: the options differ between otherwise identical 8452 units.
