B-LINE FD3015 – Frequently Asked Questions
1) Is the FD3015 breaker rated for a 480V three-phase panel?
Yes. The FD3015 is a three-pole breaker rated 600 Vac and 250 Vdc, so a 480Y/277 or 480V delta system is within its rating. Interrupting capacity is 65 kAIC at 240 Vac and 35 kAIC at 480 Vac, so check the available fault current at your panel against the 35 kAIC figure when applying it at 480. It runs on 50/60 Hz.
2) Does the FD3015 come as a complete breaker or do I need to order a trip unit separately?
It ships complete. The FD3015 is a complete molded case breaker with a fixed thermal, fixed magnetic trip at 15A, so there is no separate trip unit or rating plug to specify. Nothing about the trip setting is field adjustable.
3) Will an FD frame breaker fit where my existing F-frame Eaton breaker is mounted?
The FD3015 is an Eaton Series C F-frame breaker of FD type, which is the standard F-frame footprint. It measures 6 in height, 4.13 in width and 3.38 in length and weighs 4.5 lb. Match those dimensions and the FD designation against the breaker coming out; a different frame letter (J, K, L) is a different footprint and will not drop into an FD space.
4) Which end of the FD3015 has the lugs, and can I feed it from the bottom?
Terminals on the FD3015 are load side. If your feeder is landing on the line end, confirm what your panel arrangement needs before you set it, because the terminal provision here is specified for the load side only.
5) Can I use this Eaton FD breaker on a 250 VDC circuit?
Yes, DC use is within rating. The FD3015 carries a 250 Vdc rating alongside its 600 Vac rating, so a 125 or 250 VDC control or battery circuit is covered. Note the interrupting figures published for it (65 kAIC at 240 Vac, 35 kAIC at 480 Vac) are the AC values.
6) What is the exact part number to order for a 15 amp three-pole Eaton Series C FD breaker?
FD3015 is the manufacturer part number. Reading the designation: FD is the frame type, 3 is the number of poles, and 15 is the amp rating. It is an Eaton Series C complete molded case breaker.
7) Why use a 15A FD frame breaker instead of a smaller molded case breaker for a small motor or control feeder?
The reason is interrupting capacity, not amperage. At 15A the FD3015 is a small load, but it brings 65 kAIC at 240 Vac and 35 kAIC at 480 Vac, which is what you need when the breaker sits close to a large transformer or service and the available fault current is high. A smaller frame with a lower AIC rating would need series ratings or current limiting to be applied in the same spot.
8) Is the trip setting on the FD3015 adjustable if the circuit nuisance trips?
No. Both the thermal and the magnetic trip are fixed on this breaker, so there is no dial to raise the instantaneous pickup. If a 15A three-pole FD is tripping on motor inrush, the fix is a different amp rating or a breaker with an adjustable magnetic trip, not an adjustment to this one.
