B-LINE P3BHFD3035G – Frequently Asked Questions
1) Will the B-Line P3BHFD3035G plug-in unit fit any busway, or only Pow-R-Way III?
It is built for Pow-R-Way III busway only. The plug-in stabs and housing are matched to that run, so it will not land on another manufacturer's busway or on an earlier Pow-R-Way generation. Order it when your existing run is Pow-R-Way III with a 50 percent internal ground bus, since the unit itself is configured for 50 percent internal grounding.
2) What voltage and short circuit levels is this 35 amp busway plug-in breaker good for?
The interrupting rating runs 100 kAIC at 240 Vac, 100 kAIC at 480 Vac, and 25 kAIC at 600 Vac. On a 600 volt system you have 25 kAIC to work with, so check your available fault current at the tap point before you commit, a 480 volt distribution run is where the full 100 kAIC applies. The breaker itself is a 3-pole, 35 amp device.
3) Is a separate ground conductor needed with this plug-in unit, or is grounding built in?
Grounding is built into the unit as 50 percent internal ground, meaning it picks up the busway's internal ground bus rather than relying on an external ground bar. The busway run it plugs into has to be the matching 50 percent internal ground configuration, if your run is a full-capacity ground or housing-ground design, specify the plug-in unit to match that instead.
4) How much space do I need on the busway run for this plug-in unit, and can one person hang it?
The unit measures 21.2 inches high, 5.43 inches wide, and 12.36 inches deep, and weighs 25 pounds. Plan clear height below the busway for the enclosure plus the operating handle access, and budget for a two-man lift or a lift tool at overhead runs, 25 pounds at arm's length on a ladder is not a one-hand job.
5) What does the HFD frame mean on this B-Line busway plug-in, and does it limit what I can swap in later?
HFD is the breaker frame designation inside the plug-in unit, catalogued under frame F, and the trip is set at 35 amps. The frame is what fixes the physical envelope and the interrupting capability, so a different amperage within the same HFD frame is a different catalog number (the 3035 in P3BHFD3035G is the 35 amp, 3-pole build). Don't plan on re-rating the unit in the field, specify the amperage you need at the order.
6) Does this busway breaker unit meet NEMA requirements for a commercial electrical spec?
It is NEMA compliant and IEEE certified. That covers the two callouts most commonly written into a busway section on a commercial drawing. For anything beyond that, match the stated interrupting ratings of 100 kAIC at 240 and 480 Vac and 25 kAIC at 600 Vac against the fault study for the panel it feeds.
7) Can I use this 3-pole unit to feed a single-phase load off a busway run?
The P3BHFD3035G is a 3-pole, 35 amp device, so all three phase poles are switched and protected together. You can land a smaller load off it, but you are buying and tripping three poles, and single-phasing a three pole breaker is not how it is intended to be applied. For a dedicated single-phase tap, order a plug-in unit built with the pole count that matches the circuit.
