B-LINE P3BFDC3020 – Frequently Asked Questions
1) What amperage and frame size is the B-Line P3BFDC3020 busway plug-in unit?
The P3BFDC3020 is a 20 amp plug-in unit built on an F frame breaker, which covers the 15 to 225 amp range. So it is at the low end of that frame class, and the frame designation is what determines the physical breaker envelope inside the unit, not the 20 amp trip setting.
2) Will a 20A Pow-R-Way III plug-in unit hold up on a 480V system with high available fault current?
Interrupting capacity on this unit is 200 kAIC at 240 Vac, 100 kAIC at 480 Vac, and 35 kAIC at 600 Vac. At 480 volts you have 100 kA of interrupting capability, which covers most service-entrance-adjacent busway runs. Check the available fault current at the plug-in location against those figures before you commit.
3) Is this a standalone circuit breaker or does it need a busway to mount to?
This is a plug-in unit, not a loose breaker. The P3BFDC3020 houses a 20 amp F frame breaker and plugs directly into an Eaton Pow-R-Way III busway run to tap power at that point. It has no independent enclosure mounting for a wall or a panelboard, so it only makes sense if you already have Pow-R-Way III bus installed.
4) How big and how heavy is the P3BFDC3020 plug-in unit? I need to know if one person can hang it.
It weighs 25 pounds and measures 21.2 by 12.36 by 5.43 inches. That is a one-man lift in most cases, but on an overhead busway run at height you will want a second set of hands or a lift to line up the stabs safely.
5) What part number do I quote for a 20 amp Pow-R-Way III plug-in unit?
Quote P3BFDC3020. That is the manufacturer part number for the 20 amp F frame Pow-R-Way III plug-in unit. Other amperages in the same family share the P3BFD prefix and differ in the trailing digits, so verify the last three characters match the amp rating you need.
6) Can I use this plug-in unit on a 600 volt busway run?
It carries a 35 kAIC interrupting rating at 600 Vac, so it is applied at that voltage, but with far less fault clearing margin than the 100 kAIC it holds at 480 Vac. On a 600 volt system, confirm the available fault current at that tap point does not exceed 35 kA.
