IK protection refers to the level of protection provided by enclosures for electrical equipment against external mechanical impacts. It is defined by the International Electrotechnical Commission IEC 62262 standard, which specifies the degrees of protection provided by enclosures for electrical equipment against external mechanical impacts.
The IK code, also known as the “Impact Protection” code, ranges from IK00 to IK10, with IK10 providing the highest level of protection against mechanical impacts. Each IK rating indicates the degree of protection against impact energy measured in joules.
