B-LINE P3BHJD3125N – Frequently Asked Questions
1) What amperage and breaker frame is the B-Line P3BHJD3125N plug-in unit built around?
The P3BHJD3125N is a 125 amp plug-in unit using a J Frame breaker, and the J Frame covers 70 to 225 A. So if your load calculation lands above 125 A you need a different unit off the same frame rather than this one.
2) Will a 125A Pow-R-Way III plug-in unit hold up on a 480V system with high available fault current?
Interrupting ratings on this unit are 100 kAIC at 240 Vac, 65 kAIC at 480 Vac, and 25 kAIC at 600 Vac. At 480 V you have 65 kA of withstand, so compare that to the available fault current from your utility study at the plug-in location. If your 480 V service calculates above 65 kA, this unit is not the right selection.
3) Does the P3BHJD3125N busway plug-in include a full neutral for non-linear loads?
Yes, it is configured with a 100% neutral, which is what you want feeding panels with heavy non-linear or single-phase load where neutral current can approach phase current. Ground is 50% integral/housing.
4) What are the physical dimensions of this 125A busway plug-in unit for clearance planning?
The unit measures 23.26 in. height, 12.36 in. length, and 6.97 in. width. Check that against the space between your busway run and the ceiling, joists, or adjacent piping, and against the NEC working clearance in front of the unit before you commit to a tap location.
5) Is this a standalone circuit breaker or does it have to mount on a busway?
It is a circuit breaker plug-in unit for the Eaton Pow-R-Way III busway system, not a panelboard or enclosure-mounted breaker. It plugs onto the bus run to tap power at that point. If you need a breaker for a load center or switchboard, this is the wrong product family.
6) How is grounding handled on this Pow-R-Way III plug-in unit, or do I need a separate ground bus?
Grounding is 50% integral/housing, so the equipment ground path is through the unit housing itself at 50% capacity. No separate add-on ground conductor kit is part of this configuration.
7) How much does the P3BHJD3125N weigh and how many people do I need to hang it?
It weighs 47 lb. That is a two-person lift at height on a busway run, or a one-man lift with a hoist or platform. Plan the rigging before you get on the lift with it.
