Product FAQs
6 answersWhich panelboards accept the FJ2B150 circuit breaker?
This breaker is designed to install directly into classic Siemens and ITE F1, F2, SB1, SB2, and SB3 panelboards and switchboards.
Is the Siemens FJ2B150 a current production model?
The FJ2B150 is a legacy F-frame breaker. While newer Sentron series breakers are often used as modern upgrades, installing the exact FJ frame replacement avoids the need for special mounting adapter kits in older enclosures.
Does the FJ2B150 support direct current applications?
Yes, in addition to its standard AC ratings, this breaker is certified for use in DC electrical systems up to 250VDC with a 10kA interrupting capacity.
How is the FJ2B150 installed into the panel?
It utilizes a bolt-on mounting style, requiring the breaker to be mechanically fastened directly to the panelboard bus bars for a secure connection.
Can I adjust the trip curve on the FJ2B150?
No, this breaker is built with fixed thermal and fixed magnetic trip elements. The long-time and instantaneous protection settings cannot be adjusted in the field.
What does the LI trip function code mean on this breaker?
The LI designation indicates that the breaker provides Long-Time thermal protection against standard overloads and Instantaneous magnetic protection against severe short circuits.
