B-LINE P3BEHD3045G – Frequently Asked Questions
1) What amperage and interrupting rating does the B-Line P3BEHD3045G plug-in bus plug provide?
The P3BEHD3045G is a 45 amp plug-in unit built on an E frame breaker, and it interrupts 18 kAIC at 240 Vac and 14 kAIC at 480 Vac. Check those AIC numbers against the available fault current at the point on the busway where you are tapping. If your study calls for more than 18 kAIC at 240 V, this unit is not the right plug.
2) Will this bus plug fit an Eaton Pow-R-Way III busway run?
Yes. The P3BEHD3045G is an Eaton Pow-R-Way III circuit breaker plug-in unit, so it is made to land on Pow-R-Way III busway. It is not a plug for other manufacturers' busway or for earlier Pow-R-Way generations.
3) How much space and support do I need to hang a P3BEHD3045G plug-in unit?
Plan for a unit measuring 21.2 x 12.36 x 5.43 inches and weighing 25 lb. At that weight it is a two-hand lift onto the busway at height, so budget for a lift or a second person, and leave clearance below the plug for the load cable exit and for working room at the operating handle.
4) Can I use a 45A E frame bus plug on a 480 volt busway?
Yes, within its rating. The unit is listed at 14 kAIC at 480 Vac and 18 kAIC at 240 Vac, so it is usable on either system voltage provided the available fault current at that tap point stays under the applicable figure. The 45A E frame breaker sets the load side limit either way.
5) What is the exact part number to order for a 45 amp Pow-R-Way III breaker plug?
Order by manufacturer part number P3BEHD3045G. That single number covers the whole configuration: E frame breaker, 45 amp trip, 50% internal ground. There are no separate finish or option codes to add to it.
6) I need a different amp size on the same busway. Does the E frame cover it?
The E frame used in this plug covers 15 to 225 A, so the same frame family spans a wide range of trip ratings for other taps on the run. This particular unit is fixed at 45 A, so a different load means a different part number within that frame range, not a change to this one.
