Enclosure Insulation & Ratings

Q: What is the R rating for Bison Profab’s enclosure insulation?

We manufacturer NEMA 3R enclosures. NEMA 3R enclosures are designed very similar to NEMA 3 enclosures, however 3R enclosures can be ventilated. When ventilated, the degree of protection provided by NEMA 3R enclosures against windblown dust is diminished. Click here for more details on NEMA 3R enclosures.
