Xiria Metering Solutions offers flexibility. The open metering panel combines flawlessly with Xiria Block and Xiria Extendable Type panels while the highly compact solution integrates all measurement transformers in the cable compartment of a regular Xiria panel. This benefits small floor spaces.

SF6 free switchgear

Using vacuum technology instead of SF6 not only makes Xiria the best for the environment, but also minimizes maintenance, enhances operational safety, greatly increases the number of safe switching operations, and eliminates costly end-of-life disposal procedures. Eaton campaigns for SF6 free switchgear to protect our environment.

Compact switchgear with high flexibility

Xiria offers a high level of operational safety and is suitable for applications up to 24 kV. The Xiria product family is designed around Eaton’s proven vacuum interrupters, which require no maintenance and are certified for 30,000 operation cycles. All live parts in the available panels are single pole insulated. The used materials are shaped specifically to provide optimum insulation combined with excellent thermal characteristics. In addition, the insulation is configured to provide effective control over electric fields around the used components, thereby minimizing any risk of internal arcing. Within Xiria both the primary parts and the mechanisms are contained in a fully enclosed housing which protects the whole system against environmental influences.
