Product FAQs
8 answersWhat do the letters FFG indicate in the EGS3070FFG catalog number?
The "FF" indicates the breaker has a fixed thermal and fixed magnetic trip unit. The "G" signifies that standard line and load terminals (lugs) are included.
What does the "S" in the EGS3070FFG catalog number represent?
In the Eaton Series G nomenclature, the "S" indicates the standard interrupting capacity tier for the EG frame, which provides 35kAIC at 480VAC and 85kAIC at 240VAC.
Can the trip settings on the EGS3070FFG be adjusted?
No, this breaker features 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.
What wire sizes are compatible with the standard lugs on the EGS3070FFG?
The factory-installed lugs accept 14 AWG to 1/0 AWG copper or aluminum wire. Ensure proper torque specifications are followed during installation.
How is the EGS3070FFG mounted in an enclosure?
It is a unit-mount (feed-thru) breaker, meaning it is bolted directly to the mounting surface or backpan rather than plugging onto a busbar.
Can the EGS3070FFG be installed in a standard residential load center?
No. This is a unit-mount, feed-thru molded case circuit breaker designed for Eaton Series G enclosures, switchboards, and motor control centers (MCCs), not standard plug-on residential panels.
Are Series C accessories compatible with the EGS3070FFG?
No. The EGS3070FFG is an EG-frame breaker within the Series G family. It requires Series G internal accessories, such as auxiliary switches or shunt trips, and is not cross-compatible with older Series C F-frame accessories.
What safety precautions should be taken before installing the EGS3070FFG?
Always de-energize the switchboard or MCC before installation. Verify that the system voltage and available fault current do not exceed the breaker's maximum ratings, such as 35kAIC at 480VAC or 22kAIC at 600Y/347VAC.
