Product FAQs

6 answers
What types of equipment is the 3VA5225-7EF31-0AA0 designed to be installed in?

This 250A panel-mount breaker is designed for use in compatible Siemens panelboards and switchboards. It is not intended for standard residential load centers.

Does this breaker come with terminal lugs included?

No. The -0AA0 suffix in the catalog number indicates this breaker is supplied without line and load lugs. Lugs or alternate connection technologies must be purchased separately for field installation.

Are the trip settings adjustable on this 250A breaker?

Yes, this thermal-magnetic breaker features both adjustable thermal (long-time overload) and adjustable magnetic (instantaneous short-circuit) trip settings. This allows electricians to fine-tune the protection curve for specific load requirements.

Is this breaker suitable for high-fault commercial applications?

Yes. With a 100kA interrupting rating at 480V and 200kA at 240V, this breaker is designed for commercial and industrial systems with high available fault currents.

Can this breaker replace older Siemens 250A models?

Yes, the 3VA5225-7EF31-0AA0 serves as a modernized replacement for legacy 250A Siemens Sentron breakers, such as the JXD63B250. Note that mounting hardware or panel modifications may be required when upgrading from older frames.

Is the 3VA5225-7EF31-0AA0 suitable for reverse feed applications?

Yes, Siemens 3VA52 thermal-magnetic trip circuit breakers are UL listed for reverse feed applications, making them suitable for use in systems where power can flow in either direction.
