The degree of protection adopts the IP×× rating standard recommended by the International Electrotechnical Commission (IEC). The installation level is different for different installation sites. The IP (INGRESS PROTECTION) protection rating system is drafted by IEC (INTERNATIo nAL ELECTROTECHNICAL COMMISSION). The appliance is classified according to its characteristics of dustproof and moisture proof. The IP protection level is composed of two numbers. The first number indicates the level of the lamp from dust and the intrusion of foreign objects. The second number indicates the degree of airtightness of the lamp against moisture and water intrusion. The larger the number, the more the protection level is. high. The "IP44" can be selected by referring to the following description. In the grading standard, “×׆is a two-digit number, the first position indicates the degree of protection against solids, and the second position indicates the degree of protection against liquids. The solid protection grade has 7 grades, which are represented by 0-6 respectively; the liquid protection grade has 9 grades, which are represented by 0-8 respectively. The specific instructions are as follows:
The meaning of the first digit after IP
0 No protection, no special protection
1 It can prevent solid foreign objects larger than 50mm in diameter from entering the casing, which can prevent large areas (such as hands) of the human body from accidentally touching the charged or moving parts of the casing, but cannot prevent conscious access to these parts.
2 It can prevent solid foreign objects larger than 12MM from entering the casing, which can prevent the fingers from touching the live or moving parts of the casing.
3 It can prevent solid foreign objects larger than 2.5mm in diameter from entering the casing, which can prevent tools, metals, etc. with thickness (or diameter) greater than 2.5 from touching the live or moving parts of the casing.
4 It can prevent solid foreign objects larger than 1MM in diameter from entering the casing, which can prevent tools, metals, etc. with thickness (or diameter) greater than 1MM from touching the live or moving parts in the casing.
5 It can prevent dust from entering to the extent that it affects the normal operation of the product, and completely prevents touching or moving parts in the casing.
6 Completely prevent dust from entering and completely prevent access to live or moving parts of the case.
The meaning of the second digit after IP
0 No protection, no special protection.
1 Anti-drip, vertical dripping should not directly enter the inside of the product.
2 15 ã‚š Anti-drip, dripping water within 15 degrees of the vertical line should not directly enter the product.
3 Anti-watering, the water in the range of 60 degrees from the vertical line should not directly enter the inside of the product.
4 splash-proof water, splashing water in any direction should have no harmful effects on the product.
5 Waterproof, water spray in any direction should have no harmful effects on the product.
6 Violent waves or strong water spray should have no harmful effects on the product.
7 Immersion prevention, the product is immersed in water under the specified time and pressure, and the water intake should have no harmful effects on the product.
8 Diving, the product is immersed in water for a long time under the specified pressure, and the water intake should have no harmful effect on the product.
For example: Ip68:
This 6 says that dust can't enter (dusty). This 8 is the most advanced waterproof. This grade of motor is completely sealed. It works fine under water.
