B-LINE P3BKDC3400N – Frequently Asked Questions

1) Will this 400A plug-in unit fit any busway, or only Eaton Pow-R-Way III?
It is built for Eaton Pow-R-Way III busway and plugs onto that run only. The plug-in housing and stab arrangement are specific to the Pow-R-Way III design, so it will not land on another manufacturer's bus or on a different Eaton busway generation. Confirm the run is Pow-R-Way III before ordering model P3BKDC3400N.
2) What short circuit rating does the P3BKDC3400N give me at 480V?
100 kAIC at 480 Vac. The same K Frame breaker is rated 200 kAIC at 240 Vac and 50 kAIC at 600 Vac, so if your available fault current at the plug-in location is inside those numbers on the study, the unit covers it without adding upstream current-limiting fuses.
3) Is this a three-phase plug-in unit, and does it include a neutral?
Three-pole, with a 100% rated neutral, so it serves a three-phase load and the neutral is sized for full load current rather than reduced. That matters on feeders with heavy single-phase or harmonic-producing loads where a half-rated neutral would not do.
4) How much room and rigging do I need to hang this 400A busway plug?
Plan for a unit measuring 34.41 x 13.29 x 7.79 inches and weighing 53 lb. At that weight it is a two-person lift overhead, and most crews use a plug-in hoist or lift to engage it on the bus run. Check clearance below the busway for the full 34.41 inch height plus working space in front of the breaker handle.
5) Can I use this 400A plug-in unit on a smaller load, like a 200A feeder?
Yes, the breaker is a K Frame device covering 70 to 400 A, and this unit is factory set at the 400A rating. Using it on a smaller feeder is fine electrically, but the branch conductors and downstream equipment still have to be protected at the 400A setting, so a lighter frame plug is usually the cheaper and more appropriate choice for a 200A tap.
6) Does this breaker plug meet NEMA requirements for an institutional electrical spec?
The unit is NEMA compliant and IEEE certified, which is what most facility and government specs ask for on busway plug-in devices. Those are the standards stated for model P3BKDC3400N.
7) What is the difference between a KDC breaker plug and a fusible switch plug on busway?
This unit is a breaker plug: the disconnecting and overcurrent device is a molded case K Frame circuit breaker, so after a trip you reset the handle instead of stocking and replacing fuses. A fusible plug-in switch needs matched fuse replacements on hand and gives you current limiting from the fuse itself. For a 400A three-phase tap where maintenance staff will be resetting the device, the KDC breaker plug is the simpler unit to own.
