IP (Ingress Protection) protection level system is drafted by IEC (International Electrotechnical Commission) and classifies the electrical appliances according to the characteristics of its dustproof and humidity. The IP protection level is composed of two numbers. The first number represents the level of electrical dustproof and the level of preventing foreign objects from invasion (the foreign objects referred to here contain tools, and human fingers cannot be exposed to the charged part of the electrical appliances. In order to avoid electric shock), the second number represents the degree of conflict between the moisture and waterproof invasion of electrical appliances, the larger the number indicates that the higher the protection level.

IP protection level representation method overview

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

The first digit indicates the scope of the device's anti -dust, or the degree of people from the harm in the sealing environment. The highest level of preventing solid foreign bodies is 6;

The second digit indicates the degree of equipment waterproof. To represent the level of preventing water, the highest level is 8.
