B-LINE P3BHJD3175G – Frequently Asked Questions
1) What amperage and breaker frame does the B-Line P3BHJD3175G plug-in unit come with?
The P3BHJD3175G is a 175 amp plug-in unit built around a J frame breaker, and the J frame covers 70 to 225 amps. So if your feeder tap is sized at 175 amps, this is the unit that matches it directly rather than needing a different frame class.
2) What is the interrupting rating on the Pow-R-Way III 175A plug-in unit, and will it hold up on a 480V system?
Interrupting ratings run 100 kAIC at 240 Vac, 65 kAIC at 480 Vac, and 25 kAIC at 600 Vac. On a 480 volt busway run, you have 65 kAIC of fault current withstand, which covers most commercial and industrial service entrances. Check the available fault current at the tap point against those numbers before you commit.
3) Does this Eaton Pow-R-Way III plug-in unit include a ground, or do I need a separate ground bus?
The P3BHJD3175G is configured with 50% internal grounding, so the ground path is built into the unit itself. If your specification calls for a full-size or external ground bus arrangement, this one will not meet it and you need a different grounding configuration.
4) Will a Pow-R-Way III plug-in unit fit any manufacturer's busway?
No. The P3BHJD3175G is an Eaton Pow-R-Way III plug-in unit and it is built to land on Pow-R-Way III busway. Bus plugs are not cross-brand interchangeable, so a Square D, Siemens, or GE run needs that manufacturer's own plug-in unit. Confirm the busway nameplate says Pow-R-Way III before ordering.
5) How big and heavy is the P3BHJD3175G bus plug? I need to know what it takes to hang it.
It measures 23.26 inches high, 12.36 inches long, and 6.97 inches wide, and weighs 47 pounds. That is a two-person lift at height, and on most J frame plug-in installs you will want a hoist or a lift strap rather than trying to muscle it onto the busway from a ladder.
6) What is the exact part number to quote for the 175 amp J frame Pow-R-Way III bus plug?
Order it as B-Line P3BHJD3175G. That single number carries the Pow-R-Way III plug-in housing, the J frame, and the 175 amp trip rating with 50% internal ground, so there are no separate suffixes to specify.
7) Can I use this 175A bus plug on a 600 volt busway run?
It carries a rating at 600 Vac, but the interrupting capacity drops to 25 kAIC there, compared with 65 kAIC at 480 Vac and 100 kAIC at 240 Vac. On a 600 volt system with high available fault current, 25 kAIC may not be enough, so run the fault study before you spec this unit at that voltage.
