Eaton FD1020 – Frequently Asked Questions
1) Will the Eaton FD1020 work on a 347V single-phase circuit?
Yes. The FD1020 is rated 347 Vac and 125 Vdc, so it is suited to 347/600V Canadian lighting systems as well as DC applications at 125 Vdc. Interrupting capacity drops with voltage: 35 kAIC at 277 Vac, 18 kAIC at 347 Vac. Match the available fault current at your panel to the 347 Vac figure if that is the system voltage you are feeding.
2) Do I need to order a trip unit or anything else with the Eaton FD1020?
No. The FD1020 ships as a complete breaker with the trip unit already installed, and the trip is fixed thermal, fixed magnetic, so there is nothing to set or adjust in the field. Terminals are load side. What you may still need separately are line-side lugs or connectors suited to your conductor, and any mounting or handle accessories your enclosure or panel requires.
3) Is 18 kAIC enough for my service, or do I need a higher interrupting rating?
That depends on the available fault current at the point of installation. The FD1020 gives 18 kAIC at 347 Vac and 35 kAIC at 277 Vac. If your short-circuit study shows more available fault current than the rating at your system voltage, this breaker is not acceptable there and you need a higher-AIC frame or series-rated upstream protection.
4) Can the trip setting on the FD1020 be adjusted for a nuisance-tripping lighting circuit?
It cannot. Both halves of the trip are fixed: fixed thermal for overload and fixed magnetic for short circuit. If the 20A fixed curve keeps tripping on inrush, the fix is a different rating or an adjustable-trip electronic breaker, not a field change to this one.
5) What are the dimensions and weight of the Eaton FD1020 for enclosure layout?
The breaker measures 6 in height, 3.38 in length and 1.38 in width, and weighs 1.6 lb. That 1.38 in width is the number to watch when you are stacking single-pole F-frame units side by side inside a panel or a stand-alone enclosure.
6) Is the FD1020 usable on both 50 Hz and 60 Hz systems?
Yes, it carries a 50/60 Hz frequency rating, so it suits North American 60 Hz distribution and 50 Hz systems alike. It is also rated for 125 Vdc service.
7) Where can I get the full Eaton FD1020 spec sheet for a submittal?
Eaton publishes a spec sheet for the FD1020, and it is linked directly from the product information so you can attach it to a submittal package or an electrical plan review.
