How to Choose the Right Polycarbonate Electrical Enclosures

Polycarbonate electrical enclosures are a popular choice for protecting sensitive equipment across various industries. Their durability, versatility, and weather resistance make them the ideal solution for countless applications. But with so many options available, how do you choose the right one for your needs? This guide will walk you through the key considerations when selecting polycarbonate boxes for your projects.

1. Understand Your Application Requirements

The first step in choosing the right polycarbonate enclosure is to assess your specific application needs. Ask yourself:

  • What environment will the enclosure be used in? Polycarbonate enclosures are highly resistant to UV rays, extreme temperatures, harsh indoor environments, and moisture, making them suitable for both indoor and outdoor applications.
  • What equipment will it house? Ensure the size, internal mounting options and boss spacing can accommodate your components. To download 3D drawings and test fitment of Integra enclosures, register for an account
  • Will the enclosure require additional protection? Consider if it needs to be flame-retardant, water-proof, or tamper-proof.

2. Evaluate IP and NEMA Type 4X Ratings

Polycarbonate enclosures electrical systems often need to meet specific protection standards. Look for enclosures with appropriate IP (Ingress Protection) or NEMA (National Electrical Manufacturers Association) ratings. For example:

  • IP66 / NEMA type 4x: Provides corrosion resistance and protection against water, making it ideal for marine or industrial environments. Protects against strong water jets and dust ingress.
  • Protects against windblown dust: Ensures the safeguarding of electrical and electronic controls from dust, dirt and other airborne contaminants often found in industrial environments.
  • IP68 / NEMA type 6P: Provides maximum protection from water ingress and allows for temporary submersion, making it ideal for water treatment equipment and environments prone to flooding.

3. Consider Material Benefits of Polycarbonate Enclosures

Polycarbonate enclosures offer several advantages compared to other materials, such as metal or fiberglass:

  • Lightweight yet strong: Polycarbonate boxes are easy to install and transport without compromising durability.
  • Impact resistant: They can withstand harsh impacts without cracking or breaking, providing superior protection for electrical components against severe weather and physical impacts.
  • Transparent covers: Choose clear or opaque covers depending on whether you need to visually monitor internal components. Transparent covers are more reliable than windows and facilitate easier monitoring and maintenance of controls.

4. Think About Customization Options

Different applications may require tailored solutions. All Integra polycarbonate enclosures can be customized with:

  • Drilled holes and custom cut outs for wiring connections.
  • Multiple styles of printing or engraving.
  • A wide range of accessories for mounting, cooling, and connectors.
  • OEM shipping requirements including bulk packaging and custom labeling.

5. Ensure Compliance with Industry Standards

When working in regulated industries, confirm that the polycarbonate electrical enclosure meets applicable standards, such as:

  • UL (Underwriters Laboratories) certifications. Being UL listed ensures compliance with safety and performance standards, providing exceptional protection against environmental factors such as dust and moisture.
  • RoHS (Restriction of Hazardous Substances) compliance.
  • CE (Conformité Européenne) marking.

Additionally, ensure the enclosure offers protection against various environmental elements, including moisture and water exposure, such as splashing or hose-directed water. This highlights the suitability of the enclosures for outdoor usage, ensuring that electronic and electrical controls are protected from harsh conditions.

6. Partner with a Trusted Supplier
