Siemens 3VA6140-7HL31-0AA0 Molded Case Circuit Breaker

This 3VA6 series breaker is approved for installation in Siemens P1, P2, P3, P4, and P5 panelboards, as well as Siemens switchboards and motor control centers, provided the correct mounting hardware or strap kits are used.

The integrated ETU320 is a solid-state electronic trip unit that provides adjustable Long-Time (L) and Instantaneous (I) protection. This allows precise tuning of the breaker's trip curve to match specific load requirements and coordinate with other protective devices.

It is built on the Siemens 3VA61 frame. While this specific breaker is factory-rated for 40 amps, the 3VA61 frame footprint supports up to 150A, ensuring standardized dimensions for panel builders standardizing on the 3VA architecture.

The -0AA0 suffix in the catalog number indicates this breaker is supplied from the factory without lugs. You must purchase the appropriate Siemens 3VA lug kits separately to match your specific copper or aluminum wire gauge requirements.

It is a panel mount, feed-thru circuit breaker. When installing in Siemens P-series panelboards, you will need the specific twin-mount or single-mount strap kit designed for 3VA61 frame breakers.

The 7 designates this as a Class C high-interrupting capacity breaker. This specific class provides a 100kA interrupting rating at 480V, making it suitable for industrial environments with high available fault currents.

Solid-state trip units like the ETU320 offer greater precision, repeatability, and adjustability compared to traditional thermal-magnetic breakers. They are unaffected by ambient temperature variations, ensuring consistent protection in demanding industrial environments.
