Waterproof Junction Box: Introduction To Ip Protection Level Classification Standards

IP is the abbreviation of Ingress Protection. The IP protection rating system power terminal block provides a method to classify products based on the degree of dust, water and collision resistance of electrical equipment and packaging. This system was drafted by the International Electro Technical Commission (IEC) and announced in IED529 (BS EN 60529:1992) Outer Packaging Protection Level (IP code). This standard was also adopted as the US national standard in 2004.

The IP protection level consists of two numbers. The first number indicates the degree of dust and foreign object intrusion of the electrical appliance (here refers to din rail distribution block, human fingers, etc. cannot touch the live parts of the electrical appliance to avoid electric shock), The second number indicates the degree of power distribution block 600v sealing of the electrical appliance against moisture and water intrusion. The larger the number, the higher the protection level.

The first digit after IP is the dust protection level

The first digit indicates the range of the equipment power distribution terminal block resistance to fine dust, or the degree to which people are protected from harm in a sealed environment. Represents the level of prevention of solid foreign objects from entering, the highest level is 6:

Level 1, can block objects larger than 50mm, semi-exposed state.

Level 2, prevents the intrusion of solid objects larger than 12mm, and prevents human fingers from touching the internal parts.

Level 3, prevents the intrusion of solid objects larger than 2.5mm, and prevents tools, wires or similar small foreign objects with a diameter or thickness larger than 2.5mm from intruding and touching the internal parts.

Level 4, prevents the intrusion of solid objects larger than 1.0mm, and prevents tools, wires or similar small foreign objects with a diameter or thickness larger than 1.0mm from intruding and touching the internal parts.

Level 5, has a good dustproof effect, and dust will not cause equipment damage or large accumulation.

Level 6, completely dust-free, even the interfaces and other parts are completely sealed.
