B-LINE P3BFDB3080GN – Frequently Asked Questions
1) What amperage and breaker frame does the B-Line P3BFDB3080GN plug-in unit use?
The P3BFDB3080GN is an 80 amp plug-in unit built on an F frame breaker, the frame that covers 15 through 225 amps. So if your feeder schedule calls for an 80A tap off a Pow-R-Way III busway run, this is the matching device.
2) What is the short circuit interrupting rating on the Pow-R-Way III 80A plug-in unit?
18 kAIC at 240 Vac, and 14 kAIC at both 480 Vac and 600 Vac. Check that against the available fault current at the busway tap point on your coordination study before you commit; if the calculated fault current at that point exceeds these numbers, you need a higher AIC device.
3) Does this Eaton Pow-R-Way III plug-in unit have a full neutral, and how is it grounded?
It is configured with a 100% neutral and 50% internal ground. The full-capacity neutral suits feeders serving nonlinear or single-phase loads where neutral current can approach phase current; the ground is internal to the unit, so you are not running a separate external ground conductor to it.
4) Will this plug-in unit work on any manufacturer's busway run?
No. This is an Eaton Pow-R-Way III plug-in unit and it lands on Pow-R-Way III busway. Busway plug-in openings and stab geometry are proprietary to each manufacturer's system, so it will not mount on another brand's run or on an earlier Eaton busway series. Confirm the busway nameplate says Pow-R-Way III.
5) How big and how heavy is the P3BFDB3080GN plug-in unit for planning the install?
The unit measures 21.2 in height, 12.36 in length and 5.43 in width, and weighs 25 lb. That weight matters on a busway plug-in: at 25 pounds it is a two-hand lift onto the bus at height, and most crews will want a lift or a second person for overhead runs rather than hanging it off a ladder.
6) What is the exact part number to order for this 80 amp Pow-R-Way III breaker plug-in?
Order by MPN P3BFDB3080GN. That single number carries the whole configuration: F frame breaker, 80 amp trip, 100% neutral and 50% internal ground. Changing any one of those changes the part number, so distributors matching a replacement to an existing run should read the number off the old unit's label rather than ordering by amperage alone.
7) I need a different amp rating than 80A on the same busway. Does that mean a different unit?
Yes. This unit is fixed at 80 amps. The F frame it uses spans 15 to 225 amps, so other ratings within that band exist as separate Pow-R-Way III plug-in units with their own part numbers. You cannot re-rate this one in the field, so specify the amperage you need at order time.
