| 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 the PCR. 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 EPD covers the following devices of the UniSec AIR, including related accessories and packaging. The constituent materials of UniSec AIR SDC 24kV are presented below. The weight includes also the sub-ABB component Load Break Switch GSec 24.06.16 (without packaging). The declared functional unit of the reference flow of this study is a single SDC with rating of 24kV, and the related main dimensions are 500mm for width and 1700mm for height.

| 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. Furthermore, information and data obtained from other LCA studies is also used. This includes the LCA of GSec AIR the LCA of the VD4/R Sec and the LCA of the current transformer TPU 60.15 (ABB document ID: 1VLG101365, rev. A). 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. 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 labels, glue and grease have been excluded as their weights are negligible. This same applies to packaging, where small parts such as sticking labels are even smaller fraction of the total mass. |
