B-LINE FD1025L – Frequently Asked Questions
1) What voltage and interrupting rating does the Eaton Series C FD1025L breaker carry?
The FD1025L is rated 347 Vac and 125 Vdc, at 50/60 Hz. Interrupting capacity is 35 kAIC at 277 Vac and 18 kAIC at 347 Vac. That 347 V rating is what makes it suitable for 347/600 V Canadian-style lighting panels as well as 277 V line-to-neutral circuits in a 480Y/277 system.
2) Is the FD1025L a complete breaker or just a trip unit I have to build up?
It ships as a complete molded case breaker, F-frame, FD type, with line and load terminals included. Nothing to assemble, no separate trip unit or terminal kit to order.
3) How many poles and what amperage is the FD1025L?
Single-pole, 25 amp. One pole handles a single ungrounded conductor, so for a two-wire 240 V or three-phase load you need the two- or three-pole version of the FD frame instead.
4) Can the trip setting on the FD1025L be adjusted in the field?
No. It uses a fixed thermal, fixed magnetic trip, so both the overload and the instantaneous magnetic pickup are factory set at the 25 A rating. If your coordination study calls for an adjustable instantaneous, you need a different trip style in the F-frame, not this one.
5) Is 35 kAIC enough fault current rating for my 277 V branch circuit?
At 277 Vac the FD1025L is rated 35 kAIC, which covers most 480Y/277 V lighting and branch panel applications. Step up to 347 Vac and the rating drops to 18 kAIC, so compare the drop against the available fault current at your panel before applying it on a 347 V system.
6) What are the dimensions and weight of the FD1025L breaker for panel layout?
Height 6 in, length 3.38 in, width 1.38 in, weight 4.5 lb. Use the width figure when you are checking pole spacing in an existing enclosure or panelboard interior.
7) What is the exact part number to order for a 25 amp single-pole Eaton Series C F-frame breaker?
Order Eaton Series C part number FD1025L. The FD prefix is the frame type, the 1 is single-pole, and 025 is the 25 amp rating.
8) Will this Eaton FD breaker work on a 50 Hz system overseas?
Yes, the FD1025L is rated for 50/60 Hz, so it works on either 50 Hz or 60 Hz supply. It also carries a 125 Vdc rating for DC applications.
