Polycarbonate Enclosure Box for Outdoor Use - Best Picks
Electrical systems used outdoors require higher water, dust and UV resistance, impact and temperature gradient protection. There really is a place where polycarbonate enclosure boxes excel, and it is in terms of marked weather disproof, structural efficiency, and durability.
This guide will discuss the best rated polycarbonate enclosures that you can rely on to use outside, the primary characteristics to consider before making the purchase and how you can find the right one that suits you.
Why Polycarbonate Enclosures are Perfect Enclosures in outdoor Situations
Polycarbonate (PC) is a high-performance thermoplastic which is characterized by:
- Dustproof and Waterproof Sealing (IP 66 / IP67 )
- UV Resistance for outdoor exposure
- High Impact Resistance (IK07 and above)
- Non-conductive Electrical Insulation
- UL 94-HB Flammability Rating
This makes polycarbonate boxes perfect for:
- Solar junction boxes (DCDB/ACDB)
- Industrial and CNC control panels
- Motor starters, hydraulics, and metering panels
- Outdoor electrical and communication systems
