Eaton EGB3040FFG – Frequently Asked Questions

1) What amperages does the Eaton EG-Frame three-pole breaker come in?
The EG-Frame Series G three-pole breaker is offered at 20 A and 40 A. The 40 A is part number EGB3040FFG; at 20 A there are two builds, EGH3020FFB and EGS3020FFB. All are complete breakers with the trip unit factory set, so you pick the amperage at order time rather than adjusting it in the field.
2) Will an Eaton EG-Frame breaker work on a 600Y/347 V three-phase system?
Yes. The EG-Frame Series G three-pole breaker is rated 600Y/347 Vac at 50/60 Hz, so it covers 600Y/347 wye distribution as well as the lower common system voltages below it. Being three-pole, it breaks all three phase conductors together.
3) What is the interrupting rating on the Eaton EG-Frame 40 A breaker, and is it enough for my available fault current?
The EG-Frame three-pole 40 A breaker is rated 18 kAIC at 480 Vac. If your engineer's short circuit study shows available fault current at the panel above 18 kA at 480 V, this breaker is not the right choice and you need a higher interrupting rating. Note the suffix letters on Series G part numbers denote interrupting class, so an EGH or EGS build is a different class than an EGB.
4) Is the Eaton EG-Frame breaker adjustable, or is the trip factory set?
Fixed on both elements. The EG-Frame Series G breaker uses fixed thermal and fixed magnetic trip, so there is no adjustment dial for instantaneous pickup or long-time settings. If your spec calls for an adjustable magnetic trip for motor inrush coordination, this fixed-trip version will not satisfy it.
5) I need to replace a failed breaker in an Eaton Series G panel. How do I make sure I order the identical one?
Read the part number off the face of the existing breaker and match it character for character, because the letter after EG sets the interrupting class and the digits set poles and amperage. EGB3040FFG is the three-pole 40 A; EGH3020FFB and EGS3020FFB are three-pole 20 A in different classes. Matching amperage alone is not enough, since dropping to a lower interrupting class in the same panel changes the short circuit rating of the assembly.
6) What are the physical dimensions of the Eaton EG-Frame three-pole breaker for panel space planning?
The EG-Frame three-pole body measures 3 in wide, 2.99 in deep and 5.5 in high. Use the 3 in width to check the pole spacing you have left on the panelboard interior before you order.
7) Is the Eaton Series G EG breaker UL Listed and CE marked for an institutional spec?
Both. The EG-Frame Series G breaker is UL Listed and CE Marked, which is what most commercial and institutional submittals ask for on a molded case breaker in a panelboard or switchgear lineup.
8) Does the Eaton EG-Frame breaker need a separate trip unit ordered with it?
No separate trip unit. The EG is catalogued as a complete breaker, meaning the frame and trip elements ship as one assembly with line and load terminals, ready to land conductors once it is mounted.
