___________
Interpretation of the term “rated input current” for the applicability of the standards
IEC 61000-3-3 and IEC 61000-3-11.
Introduction:
An incorrect use case of the standard was reported in SC77A/WG2, that was caused by a
misunderstanding of the words “rated current” used in the Scope clauses of IEC 61000-3-3 and
IEC 61000-3-11.
The standard IEC 61000-3-11 is considered to be applicable to a product that can operate
continuously with an input current over 16 A, whatever term is applied to this current. The words
“rated current for xxx” in this case are us
