Product FAQs
8 answersWhat enclosures or panels is the EGS3030FFG compatible with?
This EG-frame breaker is compatible with Eaton Series G enclosures, motor control centers (MCCs), and switchboards designed for unit-mount breakers.
What wire sizes are accepted by the standard lugs on the EGS3030FFG?
The included standard line and load lugs accept wire sizes ranging from 14 AWG to 1/0 AWG. Ensure you torque the terminals to the manufacturer specifications printed on the breaker label.
What does the catalog number EGS3030FFG indicate about this breaker?
In the Eaton Series G nomenclature, "EG" designates the frame size, "S" indicates the standard interrupting capacity tier, "3" specifies three poles, and "030" denotes the 30A rating. The "FF" indicates fixed thermal and fixed magnetic trip elements, while the final "G" means standard line and load lugs are included.
Can the EGS3030FFG be reverse fed?
Yes. The Eaton EGS3030FFG is suitable for reverse-feed applications. This allows you to wire the incoming power to either the top or bottom terminals, providing flexibility during panel layout and installation.
What does the "LI" trip function indicate on this breaker?
The "LI" designation means the breaker provides Long-Time (thermal) and Instantaneous (magnetic) protection. On the EGS3030FFG, both the thermal and magnetic trip settings are fixed and cannot be adjusted in the field.
Is the EGS3030FFG HACR rated?
Yes. This EG-frame breaker is HACR rated, meaning it is approved for use with heating, air conditioning, and refrigeration equipment that requires this specific certification.
How is the EGS3030FFG mounted?
The EGS3030FFG is a unit-mount, feed-thru circuit breaker. It is designed to be individually mounted using screws or hardware rather than plugging onto a busbar or bolting directly to a panelboard bus.
Is there a newer replacement for the EGS3030FFG?
Yes, Eaton is transitioning the Series G line to the newer Power Defense series. The direct replacement for the EGS3030FFG is the Power Defense PDG13G0030TFFJ, which shares the same 35kAIC at 480V rating and Frame 1 footprint.
