Circuit Protection

Siemens new 3VA molded case circuit breakers offer safe, efficient and variable application options for low and medium-voltage power distribution whether in industrial applications, infrastructure or buildings. The 3VA range of molded case circuit breakers provides UL frame sizes covering 125A to 1000A with the 3VA5 (thermal-magnetic trip unit) and 3VA6 (electronic trip unit) models, as well as IEC frame sizes covering 100A to 630A with the 3VA1 and 3VA2 models.

At this year’s Light+Building trade show, Siemens Smart Infrastructure will show the first energy management solution that holistically captures energy data in buildings. It collects data all the way to the final circuit without any additional wiring or space requirements. All electrical data – from the power feed-in to the socket outlet – can then be seamlessly integrated into building management systems and analyzed by cloud-based applications.
