This document is following the principles of IEC Guide 119. This document defines the energy efficiency aspects of switchgear and controlgear products complying with IEC 60947 (all parts), IEC 61095 and IEC 62626 (all parts), and associated assemblies complying with IEC 61439 (all parts), in the context of the overall system energy efficiency. This document references energy policy aspects, as well as product and system aspects.<\/p>\n
This document generally assumes electrical energy input, whereas the output can be a number of different products and\/or services.<\/p>\n
This document:<\/p>\n
helps to harmonize the energy efficiency requirements and guidance in product standards;<\/p>\n<\/li>\n
raises awareness that provisions in publications can generally influence energy efficiency;<\/p>\n<\/li>\n
helps to identify energy efficiency aspects;<\/p>\n<\/li>\n
promotes the use of a systems approach to energy efficiency.<\/p>\n<\/li>\n<\/ul>\n
Other than energy efficiency aspects, this document does not cover environmental impacts (see IEC TS 63058).<\/p>\n
