What is the IP20 rating?

The IP code, also known as the International Protection Marking, classifies and rates the degree of protection provided by electrical enclosures against foreign objects and moisture. The IP code consists of two digits, with each digit representing a different aspect of the enclosure's protection level. In this article, we will take an in-depth look at the IP20 rating, its significance, and the level of protection it offers.

The first digit: Solids

The first digit in the IP20 rating represents the level of protection against solid objects. In the case of the IP20 rating, the enclosure provides limited protection against solid objects larger than 12.5mm in size. This means that fingers or similar objects cannot make contact with live or moving parts inside the enclosure. However, it does not provide protection against small objects, such as tools or wires, which could potentially enter the enclosure.

The second digit: Moisture

The second digit in the IP20 rating indicates the level of protection against moisture. In the case of the IP20 rating, the enclosure offers no protection against water or moisture ingress. This means that it is suitable for indoor use only and should not be exposed to any form of liquid or damp environment. The lack of moisture protection makes the IP20 rating unsuitable for applications where there is a high risk of water exposure, such as bathrooms or outdoor installations.

Applications and considerations

The IP20 rating is commonly found in various indoor electrical installations, such as residential homes, offices, and commercial buildings, where there are no significant risks of solid objects or moisture entering the enclosure. It is important to note that while the IP20 rating provides basic protection against larger objects, it does not safeguard against potential electrical hazards or accidental contact with live parts. Therefore, it is crucial to adhere to proper electrical safety practices and regulations, regardless of the IP rating.

In summary, the IP20 rating is a moderately protective rating primarily designed for indoor use. While it guards against larger solid objects, it offers no protection against moisture or water ingress. Before selecting an enclosure with an IP20 rating, it is essential to carefully assess the application and consider any potential risks or requirements for higher levels of protection.
