Engineered for demanding industrial environments, this 100A, 3-pole MCCB belongs to the Siemens 3VA6 family. It delivers reliable power distribution and advanced system monitoring. The 150A frame device mounts into Siemens P1 through P5 panelboards, switchboards, and motor control centers. It features an ETU550 electronic trip unit with an integrated LCD for metering and adjustable LSI settings. The breaker provides a Class H breaking capacity of 65kA at 480V.
What frame size is the 3VA6110-6JP31-0AA0 circuit breaker?
This breaker is built on the Siemens 3VA61 frame, which has a maximum physical capacity of 150A. However, this specific model is factory-configured with a 100A maximum continuous current rating.
What are the capabilities of the ETU550 trip unit on this breaker?
The ETU550 electronic trip unit features an integrated LCD screen for precise configuration of Long-Time, Short-Time, and Instantaneous (LSI) protection. It allows the continuous current (Ir) to be adjusted from 40A to 100A, providing advanced selective coordination for complex electrical systems.
How does the feed-thru connection type affect installation?
A feed-thru breaker does not plug directly onto a panelboard busbar. It requires cables to be terminated at the lugs on both the line and load sides, or it must be installed using a dedicated mounting strap kit when integrated into Siemens P1 through P5 panelboards.
How does the adjustable short-time function enhance system safety?
The short-time (S) function allows the breaker to delay tripping during a short circuit for a fraction of a second. This intentional delay gives downstream breakers time to clear the fault first, isolating the electrical hazard and preventing unnecessary power loss to other critical circuits.
Which Siemens enclosures and panels are compatible with this breaker?
The 3VA6110-6JP31-0AA0 can be installed in Siemens P1, P2, P3, P4, and P5 panelboards, as well as compatible switchboards and motor control centers. Proper strap kits or mounting hardware are required based on the specific enclosure and whether it is used as a main or branch device.

Smooth Transaction, Great Seller, Solid product
I've ordered from SuperBreakers a couple times over the years. They have great customer service, knowledgeable employees, and I got my breaker in the expected timeline. I HIGHLY RECOMMEND this shop if you are a fellow circuit breaker enthusiast!
