B-LINE EGE4030FFG – Frequently Asked Questions
1) Will an Eaton Series G EGE4030FFG breaker work on a 480V three-phase system?
Yes. The EGE4030FFG is rated to 600Y/347 Vac, so 240, 480 and 600Y/347 Vac systems are all within its rating. Interrupting capacity drops as voltage climbs: 35 kAIC at 240 Vac, 25 kAIC at 480 Vac, and 18 kAIC at 600Y/347 Vac. Match the available fault current at your panel to the figure for your actual system voltage, not the headline 35 kAIC number.
2) Is the EGE4030FFG a four-pole breaker, and can I use it on a three-phase four-wire feeder?
It is a four-pole EG-frame molded case breaker, so it lands three phases plus a switched neutral or a fourth conductor on a three-phase four-wire circuit. If your feeder is three-phase three-wire and you only need three poles, this is more breaker than the circuit calls for and it will occupy more panel width than a three-pole EG unit.
3) Is 35 kAIC enough for my service, or do I need a higher interrupting rating?
The EGE4030FFG gives 35 kAIC at 240 Vac, but only 25 kAIC at 480 Vac and 18 kAIC at 600Y/347 Vac. Compare that to the available short circuit current from your utility or transformer study at the point of installation. If your 480V calculated fault current exceeds 25 kA, this breaker is not rated for the location and you need a higher AIC frame or a series-rated combination.
4) What does "complete breaker" mean when ordering the Eaton EGE4030FFG?
Complete means it ships as a finished breaker with line and load terminals fitted, not as a frame needing a separate trip unit or terminal kit. The trip is fixed thermal and fixed magnetic, so there are no adjustment dials to set in the field. Mounting hardware and accessories such as shunt trips, auxiliary contacts or handle locks are separate items.
5) Can the trip setting on this 30A Series G breaker be adjusted in the field?
No. The EGE4030FFG uses a fixed thermal, fixed magnetic trip unit, so the 30A rating is what you get, with no adjustable pickup. If your application needs adjustable instantaneous or an electronic trip for coordination, you need a different frame and trip type, not this breaker.
6) Will the EGE4030FFG fit the space I have in an existing enclosure?
The breaker measures 5.5 in height, 4 in width and 2.99 in length, and weighs 4 lb. Lay those against your gutter space and cover cutout before committing, particularly the 4 in width, since a four-pole unit takes noticeably more room than a two- or three-pole EG breaker of the same amperage.
7) What is the exact part number and frame for this 30 amp four-pole Eaton Series G breaker?
Order it as EGE4030FFG, an Eaton Series G EG-frame breaker of the EG circuit breaker type, 30A, four-pole. The EG frame designation is what determines which panelboard interiors and mounting bases it will land in, so quote the frame along with the part number when matching an existing installation.
8) Can this Eaton Series G breaker be used on 50 Hz equipment overseas or on a generator?
Yes, it carries a 50/60 Hz frequency rating, so it is usable on both 60 Hz North American power and 50 Hz systems. That also covers 50/60 Hz generator sets within its 600Y/347 Vac voltage rating.
