Description of the difference in IP waterproof ratings for waterproof distribution boxes

Waterproof distribution boxes are widely used in various harsh environments, such as outdoors, power facilities, and industrial sites. In order to ensure that these distribution boxes can effectively prevent the intrusion of moisture and dust, international standards for protection levels (IP ratings) have been developed to evaluate their protection performance. Understanding the difference in IP waterproof ratings is essential for choosing the right box. This article will explain in detail the definitions and applicability of different IP waterproof ratings to help you make a wise choice.

1. Definition of IP protection rating

IP rating, or “International Protection Marking”, is used to describe the protection of equipment against solid objects and liquids. The IP rating consists of two parts:

– **First number**: indicates the ability to resist solid objects (such as dust), ranging from 0 to 6.

– **Second number**: indicates the ability to resist water, ranging from 0 to 9.

For example, an IP65 distribution box means that it has high performance in both dust and water resistance.

2. Specific description of different IP waterproof ratings

IP44:

– Dustproof: prevents the entry of solid objects larger than 1 mm, basically dustproof

– Waterproof: Prevents water droplets from any direction from entering, suitable for places with a certain amount of moisture, such as indoor wet areas or short-term outdoor environments.

IP54:

– Dustproof: Prevents harmful dust from entering, but not completely dustproof.

– Waterproof: Prevents water splashing from any direction from entering, suitable for environments with moisture or occasional liquid splashing, such as outdoor construction sites or industrial environments.

IP65:

– Dustproof: Completely prevents dust from entering, providing comprehensive dust protection.

– Waterproof: Prevents water jets from entering from any direction, suitable for harsher outdoor environments, such as factory exteriors or open-air equipment.

IP66:

– Dustproof: Completely prevents dust from entering, providing comprehensive dust protection.

– Waterproof: Prevents strong water flow impact, suitable for more demanding environments, such as industrial cleaning areas or environments exposed to heavy rain.

IP67:

– Dustproof: Completely prevents dust from entering, providing comprehensive dust protection.

– Waterproof: It can be immersed in water at a depth of 1 meter for up to 30 minutes, suitable for underwater equipment or equipment that needs to work in a wet environment for a long time.

IP68:

– Dustproof: It completely prevents dust from entering and provides comprehensive dust protection.

– Waterproof: It can be immersed in water at a depth of more than 1 meter. The specific depth and time are based on the manufacturer’s instructions. It is suitable for deep water or long-term immersion environments, such as underwater facilities or extreme outdoor conditions.

IP69K:

– Dustproof: It completely prevents dust from entering and provides comprehensive dust protection.

– Waterproof: It can withstand the impact of high-pressure and high-temperature water flow, suitable for high-pressure cleaning equipment or high-temperature steam environments, such as the food industry or car washing facilities.

3. How to choose the right IP level

When choosing the right IP protection level, the following factors need to be considered:

– Environmental conditions: Choose the right waterproof level according to the environmental conditions where the device is located. For example, if the device is exposed to the outdoors and needs to resist rain and dust, IP65 and above are more suitable.

– Usage scenarios: Different usage scenarios have different requirements for protection levels. Indoor humid environments may only require IP44 or IP54, while outdoor or extreme environments may require IP67, IP68 or IP69K ratings.

– Maintenance and cleaning: If the equipment needs regular cleaning or maintenance, choosing a industrial power distribution box with IP66 or IP69K ratings can provide higher protection against moisture intrusion during cleaning.

Understanding the IP protection rating of outdoor electrical distribution box can help you choose the right product according to your specific needs, thereby ensuring that the equipment has good protection performance during use. The correct selection of IP ratings can not only improve the durability and reliability of the equipment, but also reduce maintenance costs and ensure the normal operation of the equipment under various environmental conditions.
