  • Waterproofing Level Classification of Distribution Boxes

    Waterproofing Level Classification of Distribution Boxes

    The waterproof level of waterproof distribution boxes is usually divided into several levels, such as IPX1, IPX2, IPX3, IPX4, etc. Distribution boxes are a component of your electrical supply system dividing electrical power feeds into subsidiary circuits while offering a protective fuse or circuit breaker for every circuit in a common enclosure. To make sure these boxes work well, the right waterproof levels must be in place. If the installation location is near a dock or car wash, requiring resistance to close-range high-pressure water flow, the. The second digit indicates the degree of waterproofness of the distribution terminal block device. The design principle of waterproof distribution box is to use special sealing materials and structural design on the basis of the original. 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. Essential for quarries or heavy industrial zones where dust concentration hits 50mg/m³ or higher.
