Fiberglass NEMA 4X Enclosures – Non-Metallic Electrical Enclosures

Non-metallic Electrical Enclosures

FRP fiberglass enclosures are becoming more popular than metal enclosures for many practical reasons.

With the same application capabilities and comparable sizes to other enclosure materials (including stainless steel, carbon steel, and other non-metallic), FRP is becoming the preferred choice of enclosure users everywhere.

With global approval ratings (not just UL & CSA) and broader outdoor ratings, nVent HOFFMAN is able to outperform the competition.

Here are a few reasons why;

  • Lighter and easier to handle than metal enclosures
  • Equal to stainless steel and far better than carbon steel in corrosion and chemical resistance
  • Non-conductive; an electrical insulator rather than electrical conductor (Inherent safety factor)
  • Much easier to punch, drill or saw
  • Less expensive to ship; lightweight
  • Allows flex without deformation
  • Ability to return to its natural shape (Metal: when misshapen will dent)
  • Isolation from live conductors & electrical shock
  • Material prevents the direct transmission of heat
  • Moisture Resistant
