B-LINE P3BFDC3015 – Frequently Asked Questions
1) What is the P3BFDC3015 busway plug-in unit rated for, and what breaker frame is inside it?
The B-Line P3BFDC3015 is a circuit breaker plug-in unit for Eaton Pow-R-Way III busway, rated 15A on an F frame breaker (the F frame spans 15 to 225 A). So it is the smallest trip rating offered in that frame, used for branch taps off the bus run.
2) Will a 15A Pow-R-Way III plug-in unit hold up on a 480V system with high available fault current?
Interrupting capacity on the P3BFDC3015 is 200 kAIC at 240 Vac, 100 kAIC at 480 Vac, and 35 kAIC at 600 Vac. On a 480V distribution run that 100 kAIC figure is what you check against your available fault current at the tap point, so most 480V service scenarios are covered without a separate series rating study.
3) Does this B-Line plug-in unit fit any busway, or only Eaton Pow-R-Way III?
It is built for Eaton Pow-R-Way III busway only. Plug-in units are matched to the manufacturer's bus stab geometry and housing latch, so a Pow-R-Way III unit will not land on another maker's run or on an earlier Eaton busway generation.
4) I need a bigger tap than 15 amps off my Pow-R-Way III bus. Is this the right part?
No. The P3BFDC3015 is fixed at 15A. If your load needs more, stay in the same F frame family (rated 15 to 225 A) and order the plug-in unit at the amperage your branch circuit calls for. The plug-in unit amperage is not field adjustable, so the trip rating is an ordering decision, not a setting.
5) How is grounding handled on the P3BFDC3015 plug-in unit?
Grounding is 50% integral/housing, meaning the ground path is carried through the unit housing back to the busway at 50 percent capacity rather than through a separate full-size ground bar. Confirm that matches the ground scheme specified for the rest of your Pow-R-Way III run so the tap is consistent end to end.
6) How big and heavy is the P3BFDC3015, and can one person install it?
The unit measures 21.2 inches by 12.36 inches by 5.43 inches and weighs 25 pounds. At that weight, hanging it on an overhead bus run is realistically a two-person lift or a one-person lift with a mechanical assist, and you want clear working space around the plug-in opening before you start.
7) Can I use this plug-in unit on a 600V busway run?
Yes, the P3BFDC3015 carries a 600 Vac rating, but the interrupting capacity drops to 35 kAIC there compared to 100 kAIC at 480 Vac and 200 kAIC at 240 Vac. On a 600V system check your available fault current against that 35 kAIC number before committing.
8) What part number do I give my distributor for this Eaton busway plug-in breaker?
Order it as B-Line P3BFDC3015. That single MPN covers the 15A F frame Pow-R-Way III plug-in unit with 50% integral/housing grounding; there are no finish or trim options to specify with it.
