B-LINE P3BHJD3070G – Frequently Asked Questions
1) Will the B-Line P3BHJD3070G plug-in unit fit any busway, or only Pow-R-Way III?
It's a Pow-R-Way III plug-in unit. The housing and plug-in stabs are built for the Pow-R-Way III busway run, so it mounts on that system only. It will not land on another manufacturer's busway or on an earlier Pow-R-Way run. Match the busway family first, then the amperage and grounding arrangement.
2) What short circuit rating does the 70A HJD plug-in breaker unit carry at 480V?
Interrupting rating runs 100 kAIC at 240 Vac, 65 kAIC at 480 Vac and 25 kAIC at 600 Vac. So on a 480V three phase distribution run with available fault current up to 65 kA, this unit is series-adequate without additional current limiting ahead of it. Above 600V it is not applicable.
3) Is the HJD frame breaker in this unit a J frame, and can I swap in a different frame size?
The breaker is a J frame, designated HJD, factory installed in the plug-in enclosure at 70 amps, 3 pole. The frame and the enclosure are matched, so you cannot drop a different frame size into the same can. Need a different trip rating in the same frame family, order the corresponding HJD catalog number; need a larger load, step to the next plug-in unit size.
4) How much does a Pow-R-Way III 70A plug-in breaker unit weigh, and can one person hang it?
It weighs 47 lb and measures 23.26 inches high by 6.97 inches wide by 12.36 inches deep. That is a two-man lift on a lift or ladder at busway height, and it is the number to use when you check your hanger spacing and access clearance along the run before scheduling the install.
5) Is a plug-in breaker unit the right choice, or should I tap the busway with a fusible switch?
A circuit breaker plug-in unit like this 70A 3-pole gives you a resettable device at the tap point, which suits plants where a machine trips and maintenance wants it back online without stocking fuses. A fusible plug-in switch is the alternative where the spec calls for fuse current limiting. Either way the tap is made by plugging into the Pow-R-Way III run, so you can relocate the load later by moving the unit to a different plug-in opening.
6) Can I use the 70A 3-pole plug-in unit on a single phase or 3-phase 4-wire load?
Three poles, so it switches and protects three phase conductors. A three phase, three wire load is the straightforward application; for a load needing a switched neutral you need a different pole configuration. The equipment ground is carried by the 50% internal ground in the unit rather than by a pole.
7) What exact part number do I order for the 70 amp HJD Pow-R-Way III plug-in with 50% ground?
Order B-Line P3BHJD3070G. That number covers the Pow-R-Way III plug-in unit with the HJD J frame breaker at 70 amps, 3 pole, with 50% internal ground. It is a single configuration, no suffixes to add.
8) Does this 70A busway plug-in unit meet NEMA requirements for a spec job?
It is NEMA compliant and IEEE certified. Those are the two references carried on the unit, and they are what to cite on a submittal alongside the 70 amp rating, J frame and the 50% internal ground arrangement.
