ITC 101: Understanding IK Ratings for Electrical Enclosures
In industrial environments, enclosures face not only dust and water ingress but also physical impacts that can compromise equipment. The IK rating system, defined by IEC 62262, provides a standardized way to measure an enclosure’s resistance to mechanical impact. The IK rating classifies the level of protection an enclosure offers against external mechanical impacts, expressed in joules (J). Each rating (from IK00 to IK10) represents a specific energy level the enclosure can withstand. For instance, IK06 indicates protection against 1 J of impact energy, while IK10 withstands up to 20 J.
