| Use advice for data set | The life cycle assessment is a “cradle-to-grave” analysis, and the system boundaries are defined according to EN 50693, as required by EPDItaly007. For transparency reasons, the manufacturing stage is further divided into an upstream and core stage. |
| Technical purpose of product or process | This Environmental Product Declaration is a “specific product EPD” with extrapolation rules. A representative product configuration is declared as reference product, and the results can be extrapolated for other configurations according to the provided extrapolation rules. The single phase GSL 4020S compose the reference flow, including the related accessories and packaging. The single phase GSL 4020S without the trolley will be analyzed through extrapolation rules derived from the reference device. General technical information of the GSL 4020S are presented below. Description GSL 4020S Ratings Rated voltage [kV] 17.5 Rated current [A] 2500 Rated short circuit breaking current [kA] 40 The GSL 4020S are manufactured by ABB manufacturing site located in Dalmine, Italy. The manufacturing site is certified according to the following standards: • ISO 9001:2015 – Quality Management Systems • ISO 14001:2015 – Environmental Management Systems • ISO 45001:2018 – Occupational Health and Safety Management Systems The constituent materials of the GSL 4020S of nominal current are presented below.

| General comment on data set | Both primary and secondary data are used. The main sources for primary data are the bill of materials (BOM), technical drawings, and site-specific foreground data provided by ABB. For all processes for which primary data are not available, generic background data originating from the ecoinvent v3.9.1 database, with system model “allocation, cut-off by classification”, are used. The LCA software used for the calculations is SimaPro 9.5. The utility consumption and waste generation by ABB, in the core manufacturing stage, is allocated to the production of one reference product according to applicable rules. For the end-of-life allocation, the “Polluter Pays” principle is adopted according to what is defined in the CEN/TR 16970 standard. However, the potential benefits and avoided loads from recovery and recycling processes are not considered because it is not required by the PCR EPDItaly007 “Electronic and electrical products and systems”. According to PCR EPDItaly007 “Electronic and electrical products and systems”, the cutoff criteria can be set to a maximum of 2% of the overall environmental impacts. In this LCA, components like stickers, glue and grease have been excluded as their weights are negligible. The same applies to packaging, where small parts such as sticking labels are even smaller fraction of the total mass. Burnishing, oiling, black oxide, and phosphate surface treatments have also been excluded due to the low amount of surface involved. |
