This Environmental Product Declaration is an average EPD which declares an average product as the reference product. According to the General Program Instructions of EPDNorge, the total environmental impacts do not vary more than ± 10 % between the declared products; however, variations may be greater for the other impact categories. The EPD covers the following devices of the VD4 p.210 family with P4 pole, including related accessories and packaging:  VD4  VD4/P  VD4/P/SA  VD4/ZS8  VD4/ZT8  VD4/Z8  VD4/Z  VD4/US  VD4/SEC VD4 stands for fixed configuration, that will be analyzed as sensitivity analysis; while the other p.210 withdrawable devices adopting P4 pole with nominal current 630A compose the reference flow, including the related accessories and packaging. The other products (withdrawable devices with 1250 nominal current) will be analyzed through extrapolation rules derived from the reference device.
