B-LINE HFDDC3125L – Frequently Asked Questions

1) Can the Eaton HFDDC3125L breaker be used on a 250 Vdc solar PV array, or is it AC only?
It is rated for both: 600 Vac and 250 Vdc. The DC/PvGard designation and the Vdc class are what make it suitable for photovoltaic DC service rather than AC distribution alone. At 125A three-pole, it is the size typically used on a combiner or recombiner output in a PV system.
2) Is HFDDC3125L a complete breaker or just an electrical frame I have to add a trip unit to?
Complete breaker. It ships as a full three-pole F-frame unit with line and load terminals included, so there is no separate trip unit or terminal kit to order to make it functional. Mounting hardware and any accessories such as shunt trips or auxiliary contacts are separate items.
3) Will a 250 Vdc rated breaker work on a 600 Vdc PV string?
No. The DC side of this breaker tops out at 250 Vdc even though the AC rating is 600 Vac. A PV array operating above 250 Vdc needs a breaker or disconnect rated for the array's maximum system voltage, not this one. Pole configuration matters too: some DC applications series poles to raise voltage capability, and the 250 Vdc figure here is what the product is rated at as supplied.
4) What are the dimensions and weight of the Eaton F-frame HFDDC3125L for enclosure sizing?
It measures 4.13 in height, 4.13 in width, 3.38 in depth, and weighs 4.5 lb. Use those numbers against your enclosure back pan and gutter space before committing; the F-frame is a compact molded case footprint, but a three-pole DC application often needs extra wiring bend room at the line and load terminals.
5) Is the Eaton DC/PvGard HFD breaker UL Listed for an inspected commercial install?
Yes, it carries a UL Listed certification. That is the mark most AHJs look for on a molded case breaker in a commercial or PV installation.
6) What is the exact part number to order this 125A three-pole DC breaker, and does the L suffix mean anything?
Order it as Eaton HFDDC3125L. Reading the number: HFD is the high interrupting F-frame type, DC marks the DC/PvGard rating, 3 is three-pole, 125 is the 125A rating, and L designates the line and load terminal configuration supplied with the breaker.
