Product FAQs
5 answersCan the Siemens 3VA5112-6ED36-0AA0 replace older ED frame breakers?
Yes, the 3VA51 frame is designed as a modern replacement for legacy Siemens ED frame breakers, such as the ED43B125. It shares a nearly identical footprint, making it easy to upgrade existing electrical apparatus. However, new mounting hardware or kits may be required depending on the panelboard.
Are lugs included with the 3VA5112-6ED36-0AA0 circuit breaker?
Yes, the "36" connection code in the part number indicates this breaker comes factory-equipped with aluminum lugs for both the line and load sides. These lugs accept 14 AWG to 3/0 AWG wire.
What does the Class H rating mean for this breaker?
The Class H designation indicates a High breaking capacity. For the 3VA5112-6ED36-0AA0, this provides an interrupting rating of 65kAIC at 480V and 25kAIC at 600Y/347V, making it suitable for commercial and industrial power distribution systems with higher fault current availability.
Can the trip settings be adjusted on the 3VA5112-6ED36-0AA0?
No, this breaker is equipped with a TM210 thermal-magnetic trip unit. The TM210 features fixed thermal (overload) and fixed magnetic (short-circuit) trip settings, meaning the trip curve cannot be field-adjusted.
What panelboards accept the 3VA5112-6ED36-0AA0 breaker?
This breaker is compatible with Siemens P1 and P2 panelboards, as well as Siemens switchboards. When installing it as a main or subfeed breaker, a specific Siemens mounting kit or strap kit will be required based on your panel's configuration.
