Product FAQs
6 answersWhat does the "FFB" suffix mean in the EGS3080FFB catalog number?
In Eaton's Series G nomenclature, the "FF" indicates the breaker is equipped with a fixed thermal and fixed magnetic trip unit. The "B" designates a bolt-on mounting configuration.
Which panelboards are compatible with the EGS3080FFB?
This EG-frame breaker is designed for installation in Eaton Pow-R-Line panelboards and switchboards that are configured to accept bolt-on Series G circuit breakers.
Can the EGS3080FFB be reverse fed?
Yes. Eaton Series G thermal-magnetic molded case circuit breakers, including the EG-frame, are suitable for reverse feed applications.
Is the EGS3080FFB interchangeable with legacy Series C F-frame breakers?
No. The EGS3080FFB is an EG-frame breaker from the Series G family. It has different physical dimensions and mounting requirements than legacy Series C F-frame breakers, such as the FD or HFD series, and cannot be used as a direct drop-in replacement.
How does the EGS3080FFB differ from the EGH3080FFB?
The difference is the interrupting capacity. The EGS3080FFB has a standard interrupting rating of 35kAIC at 480VAC, while the EGH3080FFB is the high-interrupting version rated for 65kAIC at 480VAC. Both share the exact same EG-frame physical footprint.
Does the EGS3080FFB have adjustable trip settings?
No. This breaker features a fixed thermal and fixed magnetic trip unit, meaning the long-time and instantaneous trip functions are factory set and cannot be adjusted in the field.
