Why engineers choose this Siemens device

Efficiency in design and installation: by merging protection and sensing into a single module, it reduces wiring complexity and panel space consumption. The built-in potential transformer provides a stable, isolated sensing signal that feeds into meters and protection relays without the need for separate PT hardware, enabling faster diagnostics and safer remote monitoring.

Practical use cases

• Instrumentation panels in manufacturing lines needing accurate voltage sensing for PLC and relay logic.
• Retrofit projects where spare-space is limited and a compact PT-enabled breaker is preferred.
• Low-current control circuits where external protection logic can trigger responses, while measurement signals are supplied directly to metering equipment.

Installation and compatibility tips

Ensure the device is installed in a compatible Siemens panel and wired according to the official installation instructions for 3VA5-series components. The integrated PT output should connect to sensing inputs of relays and meters designed to accept low-voltage signals. Regular inspection of connections will help maintain accurate measurements and reliable protection performance.

What you gain

Accurate, compact protection and measurement in one module, simplified maintenance, and improved visibility into your electrical protection scheme — with a Siemens-part you can trust for consistent performance across panels and facilities.
