Danfoss FC series can withstand even the harshest pressure washing environments. A NEMA/UL Type 4X rated enclosure provides maximum mounting flexibility

Outdoor installation

Many VLT® drives are installed outdoors therefore 4x ratings are available for FC series up to 90 kW and NEMA 3R up to 250 kW. NEMA is a technical standard from the National Electrical Manufacturers Association (NEMA).

This standard, unlike the IP classification, includes reliability testing under specific weather conditions for certain classes. For example, the unit is exposed to a water spray until ice forms on the exterior. Prolonged exposure to salt spray is also tested.

Improved reliability

As with the IP ratings, the user can Use specific NEMA ratings to decide the suitability of the unit for certain environmental conditions – although the unit‘s base specification always

remain valid, Danfoss offers a protective weather shield to prevent air vents becoming blocked by leaves or other debris. The LCP is also protected against UV – as is the whole enclosure.

3rd party testing

The FC-Series has received certification from an independent body, Underwriters Laboratories (UL) and has achieved Type 4X approval up to 90 kW and NEMA 3R up to 250 kW. For details, including Type 3R, refer to drive documentation.
