Eaton FD3100 – Frequently Asked Questions

1) What amp ratings does the Eaton FD-frame three-pole breaker come in?
Two ratings are offered on the Eaton Series C F-frame FD three-pole breaker: 100A as catalog number FD3100 and 150A as FD3150. Both are complete breakers with fixed thermal, fixed magnetic trip, so the trip setting is not field adjustable. Pick the amperage to match your conductor and load calculation before ordering, because there is no way to dial it in afterward.
2) Can I use an Eaton FD breaker on a 480V three-phase system?
Yes. The FD three-pole breaker is rated 600 Vac and 250 Vdc, which covers 480Y/277 and 480V delta three-phase service, plus 208 and 240V systems. Interrupting rating is 35 kAIC at 480 Vac, so confirm the available fault current at your point of installation is at or below that figure. Frequency rating is 50/60 Hz.
3) Is a 35 kAIC breaker enough for my service, or do I need a higher interrupting rating?
35 kAIC at 480 Vac is the rating on the FD three-pole breaker. Compare that to the available fault current from your utility or transformer secondary at the breaker's location. If the calculated fault current exceeds 35 kA, this breaker is not the right device and you need a higher-interrupting frame or a series-rated combination documented for the equipment. Below that figure, it is applied as a standalone device.
4) Will an FD-frame breaker fit the space I have in my panel or switchboard?
The F-frame FD breaker measures 6 in high, 4.13 in wide, and 3.38 in deep, and weighs 4.5 lb. That 4.13 in width is the number to check against your mounting pan or bus spacing, since a three-pole F frame is a single block rather than three separate poles.
5) What does fixed thermal, fixed magnetic trip mean, and should I use an adjustable breaker instead?
Fixed thermal, fixed magnetic means both the overload curve and the instantaneous short-circuit pickup are set at the factory for the breaker's amp rating and cannot be adjusted in the field. That is fine for feeders, panel mains, and general branch protection where the load is known. If you are feeding a motor and need to raise the instantaneous pickup to ride through inrush, or you need to coordinate selectively with downstream devices, look at an adjustable magnetic or electronic trip unit instead.
6) Does the Eaton FD3100 come with lugs?
Terminals are listed as load side on the Eaton Series C FD three-pole breaker. Line side terminations, panel mounting hardware, and any accessories such as auxiliary contacts, shunt trips, or handle mechanisms are separate items to specify with the order.
7) Is the Eaton Series C FD breaker UL Listed for a commercial inspection?
UL Listed, which is the listing an AHJ looks for on a molded case breaker in a commercial distribution panel, switchboard, or motor control center. No other agency marks are claimed for it.
8) Do I need a three-pole breaker or will two poles do for my load?
The FD3100 and FD3150 are three-pole breakers, meaning all three phases open together on a fault. That is what you want for three-phase motors, three-phase panels, and 480V feeders. For a single-phase 240V load, two poles is the correct device and a three-pole breaker just wastes a pole and panel width.
