B-LINE FD1020 – Frequently Asked Questions
1) What voltage and amperage is the Eaton FD1020 circuit breaker rated for?
The FD1020 is a 20A single-pole breaker rated 347 Vac and 125 Vdc, at 50/60 Hz. That 347 Vac rating is what makes it usable on 347/600V Canadian-style lighting circuits as well as standard 120/240 and 277V work.
2) What is the interrupting rating on the FD1020, and will it hold up on a high fault panel?
Interrupting capacity is 35 kAIC at 277 Vac and 18 kAIC at 347 Vac. Check the available fault current at the panel against those numbers: if your calculated fault current at a 347V feed exceeds 18 kA, this breaker is not adequate and you need a higher AIC device.
3) Will the FD1020 fit where an existing Eaton F-frame FD breaker was installed?
It is an Eaton Series C F-frame breaker of the FD type, so it matches the same frame family and mounting footprint as other F-frame FD devices. Confirm the pole count and trip rating match what you are pulling out, since this one is single-pole, 20A.
4) Is the trip unit on the FD1020 adjustable?
No. It uses a fixed thermal, fixed magnetic trip, so neither the overload nor the instantaneous pickup can be dialed in. If your coordination study calls for an adjustable magnetic setting, this is the wrong device.
5) Is the FD1020 a complete breaker or just a trip unit?
It ships as a complete molded case breaker, not a frame-only or interchangeable trip unit. Nothing else needs to be ordered to make it a functioning device.
6) How much space does the FD1020 breaker take up in the enclosure?
Dimensions are 6 x 3.38 x 1.38 inches and it weighs 1.6 lb. Use those figures when you are checking gutter space or a single-pole slot in an existing panel.
7) Does the FD1020 come with lugs?
Terminals are supplied on the load side. Line side connection depends on how the breaker is mounted, so plan your line terminations or bus connection accordingly.
8) What is the exact part number to order this Eaton breaker under?
Order it as FD1020, the Eaton Series C manufacturer part number. There is one configuration: single-pole, 20A.
