B-LINE P3BFDB3030G – Frequently Asked Questions
1) What amperage and interrupting rating does the B-Line P3BFDB3030G plug-in unit carry?
The P3BFDB3030G is a 30 amp plug-in unit built on an F frame breaker, and the frame itself covers 15 to 225 A. Interrupting rating is 18 kAIC at 240 Vac and 14 kAIC at both 480 Vac and 600 Vac. If your available fault current at the busway exceeds those figures at your system voltage, this unit is not the right tap.
2) What busway does the P3BFDB3030G plug-in unit fit?
It is an Eaton Pow-R-Way III plug-in unit, so it is made to land on Pow-R-Way III busway plug-in openings. It is not a loose circuit breaker and it is not intended to be mounted in a panelboard or bolted to another manufacturer's busway run.
3) Can I use the P3BFDB3030G on a 480 volt busway run?
Yes, within its interrupting capability. The unit is rated 14 kAIC at 480 Vac and also 14 kAIC at 600 Vac, with 18 kAIC available at 240 Vac. The breaker itself is a 30 A F frame device, so it is sized for a branch tap off the bus, not for feeder duty near the frame's 225 A ceiling.
4) Does this Pow-R-Way III plug-in unit include a ground path?
Grounding on the P3BFDB3030G is 50% internal, meaning the housing provides an internal ground connection rated at 50 percent capacity rather than a full-size or external ground bar. Confirm that matches the grounding scheme specified for the rest of your busway run before ordering.
5) How big and how heavy is the P3BFDB3030G plug-in unit for a one-person install?
Plan on two hands and a lift. The unit measures 21.2 in height, 12.36 in length and 5.43 in width, and weighs 25 lb. At overhead busway height that is a two-person or lift-assisted hang for most crews, and you need the clearance in front of the plug-in opening to swing it in.
6) If I need more than 30 amps at a tap, is this the same plug-in unit?
No. The P3BFDB3030G is fixed at 30 A. The F frame it uses spans 15 to 225 A, so a higher-amp tap on the same busway means a different catalog number in the same plug-in family rather than swapping the breaker inside this housing.
7) What exact part number should I order for a 30 amp Pow-R-Way III plug-in unit?
Order by manufacturer part number P3BFDB3030G. That single number covers the complete plug-in unit with the 30 A F frame breaker and 50% internal grounding, so there is no separate breaker or grounding option to specify.
