B-LINE P3BHFD3035N – Frequently Asked Questions
1) Will the P3BHFD3035N plug-in unit fit any busway, or only Pow-R-Way III?
This is a Pow-R-Way III plug-in unit. The breaker bucket is built to stab into Pow-R-Way III busway runs, so it is not a drop-in for other manufacturers' or other series busway. Confirm the run on the job is Pow-R-Way III before ordering.
2) What voltage and fault current can this 35A HFD plug-in unit handle?
The interrupting rating runs 100 kAIC at 240 Vac, 100 kAIC at 480 Vac, and 25 kAIC at 600 Vac. That high-interrupting HFD frame is what you want on a service close to the transformer where available fault current is high; on a 600V system, size your study against the 25 kAIC figure, not the 100 kAIC one.
3) Does this busway plug-in unit include a full-capacity neutral?
Yes, it is configured with a 100% neutral, so it will carry full rated neutral current. That matters on branch circuits feeding non-linear loads like lighting ballasts, VFDs, and IT gear, where harmonic currents load the neutral as heavily as the phases. Ground is 50% integral housing.
4) How is this plug-in unit grounded - do I need a separate ground bus?
Grounding is 50% integral/housing, meaning the equipment ground path is carried through the busway housing at 50% capacity rather than by a separate full-size ground bar. If your spec calls for an isolated or 100% ground bus, this configuration will not meet it.
5) How heavy is a Pow-R-Way III breaker plug-in unit and how much room does it take on the run?
It weighs 25 lb and measures 21.2 in high, 5.43 in wide, and 12.36 in deep. At 25 lb it is a two-hand lift onto the busway stabs overhead, and the 12.36 in depth is the clearance you need in front of the run once the unit is hung.
6) What does the HFD frame designation mean on a 35 amp busway plug?
HFD is the breaker frame class inside the bucket, catalogued here as F frame. The trip is set at 35A, so the frame is larger than the trip rating - normal for molded case breakers, where one frame size covers a band of trip ratings. The H in HFD is the high interrupting version, which is why it reaches 100 kAIC at 480 Vac.
7) Is this a three-phase plug-in unit, and what load can it serve?
Three-pole, rated 35A, with a full neutral. That suits a three-phase 3-wire load, or a 3-phase 4-wire panel or equipment feed where you need the neutral for line-to-neutral loads. For a single-phase tap you would order a 2-pole unit instead.
8) What part number do I order for a 35A 3-pole HFD Pow-R-Way III plug-in unit?
The manufacturer part number is P3BHFD3035N from B-Line. Reading the number: P3B is the Pow-R-Way III bucket, HFD the breaker frame, 30 the three-pole/frame digits, 35 the amp trip, and N the 100% neutral. Change the trailing amp digits and you move to a different trip rating in the same frame.
9) What standards does this B-Line busway plug-in unit meet?
It is IEEE Certified and NEMA compliant. Those are the two designations carried on record for this unit; if your submittal calls out anything beyond them, verify against the manufacturer's certification sheet for the Pow-R-Way III line.
