B-LINE P3BHFD3045N – Frequently Asked Questions
1) What amperage and breaker frame does the B-Line P3BHFD3045N plug-in unit use?
The P3BHFD3045N is a 45 amp plug-in unit built on an F frame breaker, which covers the 15 to 225 amp range. If your feeder tap calls for a different amp rating, you stay within the same F frame family but order a different unit; the frame size is what dictates the physical breaker envelope inside the plug-in bucket.
2) What is the short circuit interrupting rating on this Eaton Pow-R-Way III plug-in unit?
It is rated 100 kAIC at 240 Vac, 100 kAIC at 480 Vac, and 25 kAIC at 600 Vac. On a 480 volt busway run fed from a large service transformer, the 100 kAIC figure is what lets it sit downstream of high available fault current without needing a series-rated study workaround. At 600 Vac the available fault current at the tap point has to be at or under 25 kA.
3) Does this Pow-R-Way III plug-in unit include a full neutral for a 3-phase 4-wire busway?
Yes, it is configured with a 100% neutral, so it suits a 3-phase 4-wire busway run where the neutral carries full load current, including panel feeds with significant single phase or nonlinear loading. Ground is handled by a 50% integral housing ground rather than a separate full-size ground bus.
4) Will this bus plug fit any brand of busway?
No. It is a Pow-R-Way III plug-in unit, so it is built for Eaton Pow-R-Way III plug-in busway. Bus plug stabs and housings are proprietary by manufacturer and series, so it will not mount to another maker's run or to a different Eaton busway series.
5) What are the overall dimensions of this 45A plug-in unit for clearance planning?
The unit measures 21.2 x 12.36 x 5.43 inches (height x length x width as listed). Check that against your busway centerline and any adjacent pipe, duct, or ceiling grid before locating the plug-in position, since the working clearance in front of the operating handle is what usually gets squeezed on a retrofit.
