Product FAQs
5 answersWhich Siemens panelboards accept the B310000S07 breaker?
This bolt-on breaker is designed specifically for use in Siemens P1, P2, P3, P4, and P5 series panelboards.
How is the B310000S07 installed in a panelboard?
This is a bolt-on breaker, meaning the line-side connections must be mechanically bolted directly to the panelboard busbars. It cannot be used in plug-on load centers.
What type of protection does the LI trip function provide?
The thermal-magnetic LI trip unit provides long-time protection against sustained overloads and instantaneous protection against short circuits. The trip settings on this model are fixed.
Can this breaker be used in a 480V system?
No, the B310000S07 is strictly rated for a maximum of 240VAC. Installing it in a 480V system violates its UL listing and poses a severe safety hazard.
Are the load lugs included with this breaker?
Yes, the B310000S07 comes factory-equipped with load-side lugs ready to accept your field wiring.
