What Are IP-Rated Enclosures?

IP (Ingress Protection) ratings are defined by the international standard IEC 60529 to specify how well an enclosure protects against the intrusion of solid particles (like dust) and liquids (like water). Each rating consists of two digits:

  • The first digit represents protection against solids (like dust)

  • The second digit represents protection against liquids (like water)

IP Rating Protection Level Typical Applications
IP54 Limited dust ingress; protected against water splashes from any direction Indoor control panels, sheltered installations
IP55 Limited dust ingress; protected against low-pressure water jets Light outdoor use, machinery enclosures
IP65 Dust-tight; protected against water jets from any direction Outdoor power boxes, industrial cabinets
IP66 Dust-tight; protected against powerful water jets and harsh weather Heavy-duty outdoor applications, marine environments

Our IP-Rated Enclosure Products

We manufacture and provide certified IP65-rated enclosures, and may support IP66 on a project basis. Please consult us for confirmation.

How to Choose the Right IP-Rated Electrical Enclosure

Understand IP ratings, environmental risks, and how to select the right protection level

Understand IP Rating Structure

IP ratings define protection against dust and water. The first digit indicates protection against solid particles, while the second digit refers to resistance against liquids such as rain or water jets.

Select the Correct IP Level

IP54 is suitable for indoor use, while IP65 and IP66 are recommended for outdoor environments where exposure to dust and water is unavoidable. Higher ratings ensure better protection and longer service life.

Match IP Rating to Application

Different environments require different protection levels. Outdoor power distribution, industrial automation, and marine environments typically require IP65 or higher to ensure reliable operation.

Focus on Sealing & Construction

A high IP rating depends on proper sealing design. PU gaskets, precision welding, and tight assembly tolerances are critical to maintaining long-term protection performance.

IP65 vs IP66 – What’s the Difference?

IP65 protects against water jets from any direction, while IP66 provides stronger protection against powerful water jets, making it suitable for harsher outdoor conditions.

Do You Need NEMA Rating?

For North American markets, NEMA ratings such as NEMA 4 or 4X are often required. These standards include additional corrosion and environmental resistance requirements beyond IP ratings.

Material Matters for IP Performance

Stainless steel enclosures offer better corrosion resistance, while powder-coated steel provides a cost-effective solution for general industrial environments.

Common Mistakes to Avoid

Choosing a lower IP rating to save cost can lead to water ingress, equipment failure, and higher long-term maintenance expenses.

Not sure which IP rating is right for your project?

Our engineering team can recommend the best solution based on your application, environment, and budget.
