PROTECTION MARKING (IP/IK)
An important point when selecting an outer casing is the protection degree against solids and liquids. The protection degree of outer casings for electrical equipment is defined according to the French standard: NF-EN 60529 (June 2000).
The higher the protection degree, the more watertight the casing will be. However, when installing an enclosure outdoors, exposure to weather conditions can cause temperature variations.
