Siemens SIVACON 8PS
Siemens' international IEC busbar trunking family — no UL 857 listing, not sold new in North America
Siemens SIVACON 8PS is one of 3 busway tracked in the SecondWatt catalogue, each with specifications, lead times and indicative secondary-market pricing.
Siemens SIVACON 8PS busbar trunking specs and IEC ratings, plus why US buyers should source Siemens XJ-L HD instead, since 8PS carries no UL 857 listing.
Role in the data center
LData is the only SIVACON 8PS member Siemens brands explicitly for the data hall, positioned for rack-level overhead power distribution with tap-off spacing matched to server-rack widths. LD, LI, and LX are the family's higher-current members and would carry main or riser distribution duty in a data center built on the 8PS platform. None of this is procurable new in North America under the SIVACON 8PS name, however, so a US or Canadian data center buyer needs Siemens' XJ-L HD line for the equivalent current-production role instead.
