Product FAQs
9 answersWhich Siemens panelboards are compatible with the 3VA5140-6EC31-0AA0?
This breaker is natively compatible with Siemens 3VA panelboards and switchboards. It can also be installed in legacy Siemens P1 and P2 panelboards when equipped with the correct mounting adapter.
Is the 3VA5140-6EC31-0AA0 rated for use in DC power systems?
Yes, this breaker is rated for direct current applications up to 500VDC, where it provides an interrupting capacity of 100kA.
What are the AC interrupting capacity limits for this 40A breaker across different facility voltages?
The breaker provides a 100kA interrupting capacity at 240VAC, 65kA at 480VAC, and 25kA for 600Y/347VAC systems.
How do the LI trip functions operate on the 3VA5140-6EC31-0AA0?
The LI designation stands for Long-Time and Instantaneous protection. The Long-Time thermal overload protection is fixed at 40 amps, while the Instantaneous magnetic short-circuit protection is adjustable to suit specific load requirements.
What is the physical frame size of the 3VA5140-6EC31-0AA0?
This breaker is built on the Siemens 3VA51 frame, which serves as the 125A maximum frame size within the 3VA5 molded case circuit breaker family.
Does the 3VA5140-6EC31-0AA0 include arc fault or ground fault protection?
No. This is a standard thermal-magnetic breaker with LI (Long-Time and Instantaneous) protection. It does not feature integrated AFCI or GFCI circuitry.
Is the Siemens 3VA5140-6EC31-0AA0 suitable for reverse feed applications?
Yes, all Siemens 3VA5 thermal-magnetic molded case circuit breakers are UL listed for reverse feed applications.
What does the "6" in the 3VA5140-6EC31-0AA0 part number signify?
In the Siemens 3VA catalog numbering system, the "6" indicates the breaker's interrupting capacity class. For the 3VA51 frame, it designates a High (Class H) breaking capacity, which delivers 65kA at 480VAC.
What wire sizes are accepted by the lugs on this breaker?
When equipped with standard Siemens 3VA51 aluminum lug kits (such as the 3VA9133-0JB10 or 3VA9133-0JA11), this breaker can accept copper or aluminum conductors ranging from 14 AWG up to 3/0 AWG depending on the specific lug installed.
