B-LINE P3BHJD3175N – Frequently Asked Questions
1) What amperage and breaker frame does the B-Line P3BHJD3175N plug-in unit use?
The P3BHJD3175N is a 175 amp plug-in unit built around a J frame breaker, and the J frame covers 70 to 225 A. So if your feeder is sized at 175 A and the panel schedule calls for a J frame device, this is the matching unit. Anything above 225 A needs a larger frame entirely.
2) What is the short circuit interrupting rating on the Eaton Pow-R-Way III 175A plug-in unit?
Interrupting capacity runs 100 kAIC at 240 Vac, 65 kAIC at 480 Vac, and 25 kAIC at 600 Vac. Check the available fault current at the tap point on your busway against the system voltage you are actually running. On a 480 V system you have 65 kAIC to work with, which is the number most engineers are checking against the study.
3) Does this Pow-R-Way III plug-in unit have a full neutral, and how is it grounded?
Neutral is 100 percent rated, so it will carry the full phase current, which matters on lighting and receptacle loads with heavy harmonic content. Grounding is 50 percent integral/housing, meaning the ground path is through the busway housing rather than a separate full-size ground bar. If your spec calls for a 100 percent ground, this configuration will not meet it.
4) How heavy is the P3BHJD3175N busway plug-in unit and how many people are needed to hang it?
It weighs 47 pounds and measures 23.26 inches by 12.36 inches by 6.97 inches. That is a two-person lift on a ladder or lift at busway height, and you want the hanging hardware and any hoist rigging staged before you break it loose from the pallet. Plan the clearance around the tap point for a body that size.
5) Can I use this plug-in unit on a 600 volt busway run?
Yes, the unit 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 V system with high available fault current, 25 kAIC is the number your coordination study has to live within.
6) What exactly is a Pow-R-Way III plug-in unit, and is it the same as a panelboard breaker?
It is a bolt-on tap device, not a loose breaker. The unit houses a J frame circuit breaker inside an enclosure that plugs directly into a Pow-R-Way III busway run to take a 175 A branch off the bus. A panelboard breaker mounts on an interior inside a panel and cannot be used in a busway plug-in opening. If you are feeding a machine or a sub-panel off an overhead bus duct, the plug-in unit is the right part.
7) I need to order a replacement busway plug-in unit, what part number do I give?
Order by B-Line part number P3BHJD3175N. That single number pins down the Pow-R-Way III plug-in unit with the 175 A J frame breaker, 100 percent neutral, and 50 percent integral housing ground. Changing the amp rating or the neutral and ground configuration changes the catalog number, so match it digit for digit against the existing unit's nameplate.
