What is the difference between IP55 and IP65?

When it comes to electrical enclosures and protection against dust and water, you may have come across the terms IP55 and IP65. These ratings are commonly used to specify the level of protection that an enclosure offers in different environments. In this article, we will delve into detail and explore the differences between IP55 and IP65, helping you understand which one suits your requirements.

IP55: What does it mean?

IP55 is an international standard that defines the level of protection provided by an electrical enclosure against solid objects and liquid ingress. The first digit "5" signifies the degree of protection from solid objects, whereas the second digit "5" represents the protection against water or liquid entry. Let's break it down further:

- Protection against solid objects: With an IP55 rating, the enclosure is protected against dust, but not completely dust-tight. It ensures that a sufficient amount of dust won't enter and interfere with the equipment inside.

- Protection against waterIP55 rated enclosure provides protection against water jets from any direction. It means that water projected by a nozzle against the enclosure's surface should not have any harmful effects on the equipment housed within.

IP65: What does it mean?

Similar to IP55, IP65 is also an international standard, but with higher levels of protection. Understanding the IP65 rating will help you determine if you need additional safeguards for your applications:

- Protection against solid objects: With an IP65 rating, the enclosure is fully protected against dust. It ensures that no dust particles enter the enclosure, offering complete protection to the equipment inside.

- Protection against waterIP65 rated enclosure provides protection against low-pressure water jets from any direction. It can withstand water projected by a nozzle against its surface without causing harmful effects to the equipment housed within.

Which one should you choose?

The choice between IP55 and IP65 depends on your specific requirements and the environment in which the electrical enclosure will be installed:

- If your equipment is located indoors or in a controlled environment where exposure to dust and water is minimal, an IP55 rated enclosure might suffice.

- If you plan to install the enclosure in harsh environments, with heavy dust or the possibility of water jets hitting the enclosure, it is recommended to opt for the higher level of protection offered by an IP65 rated enclosure.

Ultimately, it is essential to analyze the operating conditions, consider the potential risks, and consult with professionals to select the appropriate enclosure rating for your application.

In conclusion, understanding the differences between IP55 and IP65 ratings enables you to make an informed decision while selecting electrical enclosures. Whether you require protection from moderate dust and water jets (IP55) or need complete dust-tightness and resistance to low-pressure water jets (IP65), choosing the right rating ensures the safety and functionality of your equipment.
