B-LINE FD2020 – Frequently Asked Questions
1) What is the amp rating and pole count on the Eaton FD2020 breaker?
The FD2020 is a two-pole, 20 amp molded case breaker on Eaton's F-frame, Series C. Two poles means it protects a 240V single-phase two-wire circuit or two phases of a three-phase system, not a single 120V branch circuit.
2) Will the FD2020 breaker hold up on a 480V panel, and what is its interrupting rating?
Yes. The FD-type breaker is rated 600 Vac and 250 Vdc, with an interrupting capacity of 65 kAIC at 240 Vac and 35 kAIC at 480 Vac. If your available fault current at the 480V panel exceeds 35 kA, this frame is not adequate and you need a higher-AIC breaker.
3) Is the FD2020 a complete breaker or just a trip unit I have to build up?
It ships as a complete breaker. The FD2020 is a factory-assembled F-frame unit with a fixed thermal, fixed magnetic trip, so there is no interchangeable trip unit to order and no calibration settings to dial in. You get what the nameplate says: 20A, two-pole.
4) Will the FD2020 drop into a panel that currently has another F-frame Eaton breaker?
It is an Eaton Series C FD-type breaker on the F-frame, so it shares the F-frame form factor used across that family. Verify the pole count and mounting arrangement match what is coming out: this one is two-pole, and a three-pole opening will not be filled by it.
5) Does the FD2020 breaker have adjustable trip settings?
No. The trip is fixed thermal and fixed magnetic, so both the overload and instantaneous points are set at the factory and cannot be adjusted in the field. If your spec or coordination study calls for an adjustable instantaneous trip, this is the wrong unit.
6) What are the dimensions and weight of the FD2020 so I can check my enclosure space?
The breaker measures 6 in high, 3.38 in long, and 2.75 in wide, and weighs 3.15 lb. Check that footprint against the mounting pan and the gutter space in your enclosure before you commit, since F-frame units are deeper than a typical residential breaker.
7) What terminals come on the FD2020, and do I need to order lugs separately?
Terminals are load side. Confirm what is present on the line side of your existing installation, because if your panel feeds the breaker through a bus stab or a separate line-side connector, that hardware is not part of the breaker itself.
8) Can I use the FD2020 on both 50 Hz and 60 Hz systems?
Yes, it carries a 50/60 Hz frequency rating, so it works on North American 60 Hz service and on 50 Hz systems. It is also rated 250 Vdc for DC applications.
9) What is the manufacturer part number for this Eaton 20 amp two-pole molded case breaker?
The part number is FD2020. The FD prefix identifies the F-frame breaker type and the 20 at the end is the 20 amp trip rating.
