What is the protection level of the ring main unit? Such as IP65 IP3X?

The IP protection level is composed of two numbers, the first number indicates the level of dust protection and prevention of foreign intrusion, and the second number indicates the degree of airtightness of moisture and water intrusion.

Representation: The protection level is mostly expressed by two numbers followed by IP, and the numbers are used to clarify the level of protection.

The first digit indicates the range of resistance to fine dust in the device, or how well people are protected from hazards in a sealed environment. Represents the level of protection against the ingress of solid foreign matter, the highest level is 6;

The second digit indicates how waterproof the device is. Represents the level of protection against water ingression, and the highest level is 8.

IP65 IP is an abbreviation for Ingres Protection. Among them, 6 is dustproof level, 6: completely prevent dust from entering; 5 is waterproof level, 5: rinse with water without any harm.

The IP rating is the level of protection against foreign objects in the enclosure of electrical equipment** is the International Electrotechnical Commission standard IEC 60529, which was also adopted as the US National Standard in 2004. In this standard, for the protection of foreign objects in the electrical equipment shell, the format of the IP rating is IPXX, where XX is two Arabic numerals, the first mark number indicates the contact protection and foreign object protection level, and the second mark number indicates the waterproof protection level, and the specific protection level is as follows:

Ingress protection. Dust resistance rating (indicated by the first x).

0: No protection.

1: Prevent the intrusion of large solids.

2: Prevents the ingress of medium-sized solids.

3: Prevent small solids from entering and intruding.

4: Prevent the entry of solids larger than 1mm.

5: Prevent harmful dust accumulation.

6: Completely prevent dust from entering.

Waterproof rating (indicated by the second x).

0: No protection.

1: Water droplets dripping into the shell have no effect.

2: When the shell is tilted to 15 degrees, water droplets dripping into the shell have no effect 3: Water or rain has no effect from the corner of 60 degrees to the shell.

4: Liquid splashed into the shell from any direction has no harmful effect.

5: Rinse with water without any harm.

6: Can be used in the environment in the cabin.

7: It can withstand water immersion (1m) in a short time

8: Immersion in water for a long time under a certain pressure.

Protection level IP65 refers to the dustproof and waterproof test, dustproof level 6 and waterproof level 5 test.

1. The IP protection level is composed of two numbers, the first number indicates the level of dust and foreign object intrusion, and the second number indicates the degree of airtightness of moisture and waterproof invasion, and the larger the number, the more protection level.

High. 2. The "6" in IP65 means that it completely prevents the intrusion of foreign objects and can completely prevent dust from entering; "5" indicates to prevent water from being sprayed from the nozzle from all directions from entering the meter and causing damage.

2. Expansion: 1. IP

IP protection level is an important part of the safety protection of electrical equipment.

Ingress protection systems, such as IP, provide a way to classify products based on how dustproof, waterproof, and impactproof electrical equipment and packaging are.

2. This system has been recognized by most European countries, and the International Electrotechnical Association IEC (International

electro

technical

Commission) and in IED529 (BS

EN60529:1992)

code).

The protection level is mostly expressed by two numbers followed by IP, and the number is used to clarify the level of protection.

3. The first number indicates the range of resistance of the device to fine dust, or the degree to which people are protected from hazards in a sealed environment. i stands for the level of protection against the ingress of solid foreign matter, and the highest level is 6;

The second word An indicates the degree to which the device is waterproof.

4. P stands for the level of preventing water ingress, and the highest level is 8.

For example, the protection level of the motor is IP65, the protection level is IP55 and so on.

IP65 IP is the abbreviation of ingress protection, IP rating is the protection level against foreign body intrusion of electrical equipment shells, such as: explosion-proof appliances, waterproof and dustproof appliances, ** is the International Electrotechnical Commission standard IEC 60529, this standard was also adopted as the American national standard in 2004.

The IP (Ingress Protection) protection rating system is drafted by the International Electronic Technical Commission (IEC), which classifies electrical appliances according to their characteristics of dust and moisture resistance.

The IP protection level is composed of two numbers, the first number indicates the level of dust proof and prevention of foreign object intrusion of electrical appliances (the foreign objects referred to here include tools, human fingers, etc., can not touch the live head part of the electrical appliances to avoid electric shock), the second number indicates the degree of sealing of the electrical appliances against moisture and waterproof immersion, and the larger the number, the higher the protection level.
