B-LINE P3BJDB3070N – Frequently Asked Questions
1) What amperage and breaker frame does the B-Line P3BJDB3070N plug-in unit come with?
It is a 70 amp unit built on a J frame breaker, and the J frame covers 70 to 225 A. So 70 A is the bottom of that frame range, which means the housing is the same size you would get on a larger J frame plug-in of the same series.
2) Is the P3BJDB3070N rated for a 480V busway run?
Yes. The interrupting rating is 65 kAIC at 240 Vac, 35 kAIC at 480 Vac and 18 kAIC at 600 Vac, so it can be applied up to 600 Vac. Check the available fault current at the tap point against the 35 kAIC figure for a 480 Vac system before you commit it to the run.
3) Does this Pow-R-Way III plug-in unit have a full neutral?
Neutral is 100 percent rated, so it will carry full load current on the neutral, which is what you want on a busway feeding single phase or harmonic-heavy loads. Grounding is 50 percent integral housing ground rather than a full-size separate ground conductor.
4) Is the P3BJDB3070N a bare circuit breaker or a complete busway tap unit?
It is a complete plug-in unit: an enclosed housing with the J frame breaker inside, designed to plug onto an Eaton Pow-R-Way III busway run. You are not buying a loose breaker to mount in a panel, you are buying the tap device for the bus.
5) Will this plug-in unit fit an Eaton Pow-R-Way III busway I already have installed?
It is built as a Pow-R-Way III plug-in unit, so it mates with Pow-R-Way III busway plug-in openings. It is not a substitute for plug-in units on other busway systems, including earlier Pow-R-Way generations, since the plug-in stab arrangement differs between systems. Match the busway system name on your existing run before ordering.
6) How heavy is a J frame Pow-R-Way III plug-in unit, and can one person hang it?
The unit weighs 47 lb. At that weight, plan on two people or a lift to get it onto the busway plug-in opening at height. It measures 23.26 in high, 12.36 in long and 6.97 in wide, so allow clearance around the plug-in port for the body of the housing.
7) What is the exact part number to order for a 70 amp J frame Pow-R-Way III plug-in unit?
Order B-Line P3BJDB3070N. That single model number carries the 70 A J frame breaker, the 100 percent neutral and the 50 percent integral housing ground, so there are no separate suffixes to specify for those options.
