B-LINE P3BFDB3050G – Frequently Asked Questions
1) What amperage and breaker frame does the B-Line P3BFDB3050G Pow-R-Way III plug-in unit use?
The P3BFDB3050G is a 50 amp plug-in bus plug built on an F Frame breaker, a frame that covers 15 through 225 amps. So if your feeder tap needs 50 A of protection off a Pow-R-Way III busway run, this is the unit sized for it. Larger or smaller taps on the same F frame are handled by a different catalog number in the same family.
2) What is the interrupting rating on this 50 amp Pow-R-Way III bus plug, and will it hold on a 480 volt system?
Interrupting capacity is 18 kAIC at 240 Vac and 14 kAIC at both 480 Vac and 600 Vac. On a 480 V distribution system you have 14 kA of fault clearing, so compare that against the available fault current calculated at the tap point on your busway run. If the study shows more than 14 kA at that location, this unit is not the right choice.
3) Can I use this B-Line plug-in unit on any brand of busway?
No. The P3BFDB3050G is a Pow-R-Way III plug-in unit, so it is built to land on Eaton Pow-R-Way III busway. Plug-in openings, stab geometry and ground arrangement differ between busway systems, so it is not a drop-in on another manufacturer's run or on an earlier Pow-R-Way generation.
4) Does the P3BFDB3050G bus plug include a ground, or do I need a separate ground bar?
Grounding on this unit is 50% internal, meaning the ground path is carried internally through the plug-in at 50 percent capacity rather than requiring you to field-add a separate grounding conductor kit. Match that to how the busway run itself is specified, since the plug and the busway grounding scheme need to agree.
5) How big and how heavy is the Eaton Pow-R-Way III 50 amp plug-in unit for planning the hang?
It measures 21.2 inches in height, 12.36 inches in length and 5.43 inches in width, and weighs 25 pounds. That weight matters for the install method: a 25 pound unit going onto an overhead busway run is a two-man lift or a lift assist on most ceilings, and you need the clearance below the busway to swing 21.2 inches of enclosure into the plug-in opening.
6) Is the P3BFDB3050G a standalone circuit breaker or a complete bus plug assembly?
It is a complete breaker plug-in unit, not a loose breaker. The enclosure, the F frame breaker and the plug-in stabs come as one assembly that lands directly on the busway and provides the tap point for your feeder. You are not buying a breaker to install into an existing can.
