What is the degree of protection ACC to IEC 60529?

The degree of protection, often referred to as IP (Ingress Protection), is a standard defined by the International Electrotechnical Commission (IEC) in iec 60529. The IP code is used to classify and rate the level of protection provided by enclosures of electrical equipment against foreign objects, such as dust, water, or accidental contact.

Understanding the IP Code

The IP code consists of two digits following the letters "IP." The first digit represents the level of protection against solid objects and particulates, while the second digit represents the level of protection against liquids. Each digit has a range from 0 to 6, indicating different degrees of protection. For example, an IP67-rated enclosure offers higher protection than an IP55-rated one.

First Digit: Protection Against Solid Objects

The first digit of the IP code indicates the level of protection against solid objects and particulates. Here is a breakdown of each level:

0: No special protection against contact and ingress of objects.

1: Protection against solid objects larger than 50mm, such as the back of a hand.

2: Protection against solid objects larger than 12.5mm, such as fingers.

3: Protection against solid objects larger than 2.5mm, such as tools, wires, or small screws.

4: Protection against solid objects larger than 1mm, such as most wires or fine tools.

5: Dust-protected, preventing the ingress of dust that may interfere with the proper operation of the equipment.

6: Dust-tight, providing complete protection against the ingress of dust.

Second Digit: Protection Against Liquids

The second digit of the IP code represents the level of protection against liquids. Here is an of each level:

0: No protection against liquids.

1: Protection against vertically falling drops of water, such as condensation.

2: Protection against direct sprays of water up to a 15-degree angle from vertical.

3: Protection against direct sprays of water up to a 60-degree angle from vertical.

4: Protection against water splashing from any direction.

5: Protection against low-pressure jets of water from any direction.

6: Protection against strong jets of water or heavy seas.

7: Protection against the effects of temporary immersion in water up to 1 meter for 30 minutes.

8: Protection against continuous submersion in water under specified conditions.

In conclusion, the degree of protection according to IEC 60529, commonly known as the IP code, provides a standardized way to determine the level of protection offered by electrical enclosures. Understanding the IP code is crucial when selecting equipment for specific environments to ensure proper operation and safety.
