Compact IP55/IP66 VLT® drive down to 0.25 kW

09 November 2009
Danfoss Drives present a compact A4 enclosure in protection class IP55/66 in the FC series down to 0.25 kW.

The new frame size covers:

1.1 – 2.2 kW / 200 – 240 V and
1.1 – 4.0 kW / 380 – 480 V

VLT AQUA Drive:
0.25 – 2.2 kW / 200 - 240 V and
0.37 – 4.0 kW / 380 – 480 V

VLT AutomationDrive:
0.25 – 2.2 kW / 200 - 240 V and
0.37 – 4.0 kW / 380 – (480)500 V

Smaller size, easier to install

The A4 frame size presents a more compact solution for customers that until now have used the A5 frame in the same power range.

The advantage of the new A4 frame size are :

  • Smaller mechanical size (32%)
  • Lighter weight (9.4 kg)
  • Easier mounting and installation for customers (outside fastening holes)
  • Easy line connection (45° connector)
  • No external fan in 0.37 – 1.5 kW /380-500V and 0.25 – 0.75 kW / 200 - 240V
  • Ambient temperature: 50°C continuously (only drive on the market!)
  • Optional mains switch
  • Threaded cable entry holes for ‘metric areas’
  • Smooth cable entry holes for conduit installations
  • Easy fieldbus connection
  • Compatible with Ethernet based fieldbus options
  • Same internal hardware and software as for A5
  • All options designed for placing in A and/or B slot(s)

In contrary to the frame size A5 the new A4 frame size does not have space for C options in the drive. For application that require a C option, the A5 frame is still the best solution.
