Product FAQs
7 answersWhat equipment is the FB3015PF circuit breaker designed to fit?
This F-Frame breaker is engineered for installation in legacy Westinghouse panelboards, motor control centers, and switchboards that accept bolt-on molded case circuit breakers.
What wire gauge and material can be used with the load side terminals?
The factory-installed load side lugs are rated for both copper and aluminum (Cu/Al) conductors, accepting wire sizes from 14 AWG to 1/0 AWG.
Are Eaton and Cutler-Hammer direct replacements for Westinghouse FB breakers?
Yes. Eaton acquired the Westinghouse electrical distribution business and integrated it under the Cutler-Hammer brand. Modern Eaton and Cutler-Hammer F-Frame breakers are the direct OEM successors to legacy Westinghouse models.
Are the thermal and magnetic trip points adjustable on this model?
No. This breaker is equipped with a fixed thermal and fixed magnetic trip unit, meaning the overload and short-circuit trip thresholds are factory-set and cannot be modified in the field.
Can the FB3015PF be installed in direct current (DC) applications?
Yes, in addition to its alternating current (AC) ratings, this breaker is certified for DC systems up to 250VDC with a 10kA interrupting capacity.
How is the line side of this breaker connected to the panel?
As a bolt-on molded case circuit breaker, the line side terminals bolt directly to the panelboard busbars for a secure connection, while the load side uses standard mechanical lugs.
What type of protection does the LI trip function provide?
The LI code indicates that the thermal-magnetic trip unit delivers Long-Time (L) protection against sustained overloads and Instantaneous (I) protection against severe short circuits.
