IK Rating

You may have noticed on our website we quote products with an IK rating (where applicable and when provided to us from the manufacturer) and you may have wondered what that the IK rating means. Well the IK rating relates to the European standard EN 62262 - the equivalent of international standard IEC 62262 (2002).

This is an international numeric classification for the degrees of protection provided by enclosures for electrical equipment against external mechanical impacts. It provides a means of specifying the capacity of an enclosure to protect its contents from external impacts. So in essence it tells you how resistant to an external impact/shock a product is and therefore helps you choose the right product for the right job. We hope this helps in your decision making.


Impact Protection (IK) Rating
