Product FAQs
6 answersWhich panelboards are compatible with the FJ63B200 circuit breaker?
This bolt-on breaker is designed for use in Siemens P1, P2, and P3 panelboards, as well as SB switchboards. It is also backward compatible with legacy I-T-E F-Frame panelboards.
Can I use the Siemens FJ63B200 to replace an older I-T-E breaker?
Yes, the Siemens FJ63B200 is a direct replacement for legacy I-T-E FJ63B200 breakers. Siemens acquired I-T-E, so this breaker will fit into existing I-T-E F-Frame enclosures without modification.
Are the lugs on the FJ63B200 rated for aluminum wire?
Yes, the standard factory lugs are dual-rated for both copper and aluminum (Cu/Al) conductors. They accept wire sizes from 6 AWG up to 350 kcmil.
Can the FJ63B200 be used in DC power systems?
Yes, this breaker is rated for up to 250VDC with a 10kA interrupting capacity. This makes it suitable for certain DC power distribution applications, in addition to its standard AC ratings.
Does the FJ63B200 allow for field adjustment of the trip curve?
No, this breaker features fixed thermal and fixed magnetic trip elements. It provides standard Long-Time and Instantaneous (LI) protection, but the trip thresholds cannot be adjusted by the user.
What safety functions does the FJ63B200 provide?
It provides thermal-magnetic protection, safeguarding electrical systems against both sustained overloads via the thermal element and sudden short circuits via the magnetic element.
