B-LINE P3BJDC3090 – Frequently Asked Questions
1) What amperage and breaker frame does the B-Line P3BJDC3090 Pow-R-Way III plug-in unit use?
The P3BJDC3090 is a 90 amp plug-in unit built on a J frame breaker, a frame that spans 70 to 225 A. That means if your load grows later, the same frame family covers higher trip ratings, but this specific unit is fixed at 90 A.
2) Is the P3BJDC3090 plug-in unit rated for a high fault current service at 480V?
Yes. The interrupt rating is 200 kAIC at 240 Vac, 100 kAIC at 480 Vac, and 35 kAIC at 600 Vac. On a 480 Vac busway run, 100 kAIC covers most service entrance available fault currents, but confirm the calculated fault current at the tap point rather than at the transformer.
3) Can I use this B-Line plug-in unit on 600 volt busway?
It carries a rating at 600 Vac, but the interrupting capacity drops to 35 kAIC there, versus 100 kAIC at 480 Vac and 200 kAIC at 240 Vac. On a 600 V system you need the available fault current at that tap to be under 35 kA.
4) How big and how heavy is the P3BJDC3090 plug-in unit for overhead busway installation?
It measures 23.26 in height, 12.36 in length, and 6.97 in width, and weighs 47 lb. At that weight this is a two-person or lift-assisted install on overhead busway, and you need clear working space around the plug-in opening before hanging it.
5) What exactly is a Pow-R-Way III plug-in unit like the P3BJDC3090, and how is it different from a panelboard breaker?
It is a self-contained circuit breaker in an enclosure that plugs directly into an Eaton Pow-R-Way III busway run to tap power at a point along the bus. A panelboard breaker needs a panel, feeder conduit, and a fixed location. The plug-in lets you take 90 A off the busway wherever you need it and relocate it later as equipment moves, which is why these are common in plants and data centers.
6) What part number do I order for a 90 amp J frame Pow-R-Way III plug-in unit?
Order B-Line P3BJDC3090. That single manufacturer part number covers the complete 90 A J frame plug-in unit; there are no finish or option variants to specify with it.
