Product FAQs
6 answersWhich legacy Siemens breakers does the 3VA5580-7EC32-0AA0 replace?
This 3VA55 frame breaker is an ideal replacement for upgrading older Siemens CMD63B800 and CND63B800 800A circuit breakers.
Does this breaker mount directly into Siemens P4 or P5 panelboards?
It requires a separate panelboard mounting kit to install into P4 and P5 distribution panels. It will not mount into these chassis directly out of the box.
What does the Class C breaking capacity mean for this breaker?
The Class C designation indicates a high interrupting rating tier for the 3VA series, allowing the breaker to safely clear fault currents up to 100kA at 480VAC and 200kA at 240VAC.
What specific trip unit model is included in this breaker?
It includes a Siemens TM230 thermal-magnetic trip unit, which delivers reliable Long-Time and Instantaneous (LI) overcurrent protection with fixed thermal and adjustable magnetic settings.
How are conductors terminated on the nut keeper connections?
Nut keeper terminals do not accept bare wire directly. They are designed for bolting the breaker directly to solid busbars or for attaching separate mechanical or compression lug kits for cable wiring.
Is this breaker certified for heating and cooling equipment?
Yes, it carries an HACR rating, certifying it for safe use in heating, air conditioning, and refrigeration circuits alongside its standard UL 489 and CSA C22.2 No. 5 approvals.
