B-LINE P3BED3125 – Frequently Asked Questions
1) What amperage and frame size is the B-Line P3BED3125 plug-in unit?
The P3BED3125 Pow-R-Way III plug-in unit is rated 125A and uses an E Frame breaker, which covers 15 to 225 A. So a 125A trip sits mid-range in the frame, and the same frame family is what you'd order for other ratings on the run.
2) Will a 125A Pow-R-Way III plug-in unit hold up on a 240V service with high available fault current?
Its interrupting rating is 65 kAIC at 240 Vac. If your utility short circuit study at the busway tap comes in at or under 65 kA on a 240 volt system, the P3BED3125 is rated for it. Above that, or on a higher system voltage, you need the fault current checked against the correct rating for that voltage before it goes in.
3) Does the P3BED3125 busway plug-in unit include a ground path or do I need a separate ground bus?
Grounding is handled at 50% integral/housing, meaning the plug-in unit grounds through the housing rather than requiring a separately run ground conductor to the tap. Confirm the busway run itself is specified for the same 50% ground arrangement so the tap and the duct match.
4) How big and heavy is the P3BED3125 plug-in unit for overhead busway installation?
It measures 21.2 x 12.36 x 5.43 inches and weighs 25 lb. At that weight it is a two-hand lift onto an overhead run, and most crews stage it on a lift rather than handing it up a ladder. Check your clearance along the busway before you order, since the long dimension has to swing into the plug-in opening.
5) Is a busway plug-in unit like the P3BED3125 the right choice, or should I run a panelboard feeder instead?
A plug-in unit is for tapping loads off an existing Pow-R-Way III busway run, and it carries the breaker with it, in this case a 125A E Frame device. That's what you want when loads move or get added along a plant or warehouse run, because the tap lands anywhere there's a plug-in opening. If the loads are fixed and grouped in one place, a conventional panelboard fed by conduit is the simpler build. A plug-in unit is not a substitute for panel branch circuits; it feeds a single downstream point.
6) What is the exact part number to order for the Eaton Pow-R-Way III 125A plug-in unit?
Order it as P3BED3125, a B-Line Eaton Pow-R-Way III circuit breaker plug-in unit. That single MPN covers the 125A E Frame configuration; there are no finish or option suffixes to specify on it.
