Product FAQs
6 answersWhat legacy Siemens breaker does the 3VA5140-4ED31-0AA0 replace?
This 3VA5 series breaker serves as the modern upgrade and direct replacement for the legacy Siemens ED43B040. It fits into the same Siemens P1, P2, and P3 panelboards.
Are load and line lugs included with the 3VA5140-4ED31-0AA0?
No, this specific catalog number indicates the breaker ships from the factory without lugs. Lugs or nut keepers must be sourced separately for field installation.
Is the 3VA5140-4ED31-0AA0 rated for reverse feed applications?
Yes, this 3VA5 thermal-magnetic molded case circuit breaker is UL listed for reverse feed installations.
How must the 3VA5140-4ED31-0AA0 be wired for 500V DC applications?
While rated for 50kA at 500V DC, applying this 3-pole breaker on 500V ungrounded DC systems requires connecting the power supply in a series or zig-zag configuration across all three poles.
What does the TM210 designation mean for this breaker's trip unit?
The TM210 designation indicates a thermal-magnetic trip unit with fixed thermal (overload) and fixed magnetic (short-circuit) settings, providing standard LI (Long-Time, Instantaneous) protection.
Which Siemens panelboards accept the 3VA5140-4ED31-0AA0?
