What does the IK value mean?

The IK value, rating, or code is an international standard that measures the degree of protection provided by an electrical enclosure against mechanical impacts.

Specifically, it evaluates the enclosure's resistance to impacts from outside objects.

It is represented by a two-digit code. The first being 0 to 6, and the second being from 0 to 10.

The first digit indicates the level of protection against impact.

The other represents the energy level during the test.
