IK Ratings

They consist of the letters IK, followed by two digits. These two digits help us to identify the level of protection a piece of electrical equipment offers by its resistance against external mechanical impacts by Kinetic energy.

While EN 62262 specifies the way enclosures should be mounted when tests are carried out, the atmospheric conditions that should prevail, the number of impacts (5) and their (even) distribution, size, style, material, dimensions of the various types of hammer designed to produce the energy levels required.
