Busbar trunking has been subjected to additional fire testing

Siemens, busbar trunking

To help improve fire-safety standards in data centres, the Siemens Building Technologies range of cast-resin busbar has successfully undergone additional testing to ensure ‘fire withstand ability’ of the busbar trunking at 750°C for up to 3 h is now achievable. Copper and aluminium versions of Siemens’ cast-resin busbar trunking now conform to IEC 60331-31 (tests for electrical cables under fire conditions) and are proven to meet the standards required for life-safety and emergency supplies.

This range is rated IP68 and has a short-circuit rating of up to 100 kA for a second.
