Product FAQs
8 answersWhich Eaton panelboards accept the EGC3070FFG circuit breaker?
This EG-frame breaker is engineered for installation in Eaton Series G and Pow-R-Line panelboards, as well as compatible switchboards and motor control centers.
What type of wire can be used with the EGC3070FFG lugs?
The factory-installed line and load terminals are rated for both aluminum and copper (Al/Cu) conductors, accepting wire gauges from 14 AWG up to 1/0 AWG.
What does the "FFG" suffix indicate on this Eaton breaker?
In Eaton's Series G catalog numbering, "FFG" specifies that the breaker is equipped with a fixed thermal and fixed magnetic trip unit, and that it comes standard with line and load lug terminals.
What does the "EGC" prefix mean in the EGC3070FFG part number?
The "EGC" designation indicates that the breaker belongs to the EG-frame family and features a specific interrupting capacity tier, rated for up to 100 kAIC at 480V.
Can I adjust the trip settings on the EGC3070FFG?
No, this breaker is built with a non-interchangeable trip unit featuring fixed long-time and fixed instantaneous (LI) protection functions, meaning the trip curve cannot be field-adjusted.
Can the EGC3070FFG be used in DC electrical systems?
Yes, in addition to its AC ratings, this thermal-magnetic breaker is rated for use in DC circuits up to 125/250VDC with an interrupting capacity of 42 kAIC.
Is the EGC3070FFG interchangeable with other Eaton Series G frames?
No, this is specifically an EG-frame breaker. While it is part of the broader Series G family, it has a unique physical footprint (5.5 inches high by 3 inches wide) and cannot be swapped into spaces designed for JG, LG, or NG frames.
How does the interrupting capacity (AIC) of the EGC3070FFG change based on voltage?
The maximum interrupting capacity is 200 kAIC when used on a 240VAC system. The rating scales down at higher voltages, providing 100 kAIC at 480VAC and 35 kAIC at 600/347VAC.
