B-LINE 17X63PMURN – Frequently Asked Questions
1) Can the B-Line UNIPAK 17X63PMURN capacitor bank be mounted outdoors?
Yes. The 17X63PMURN UNIPAK capacitor bank is built in a NEMA 1, 3R enclosure, so it can go on an outdoor wall as well as indoors. The housing is 14 gauge steel with a powder coat finish. Physical envelope is 22.3 in by 8.5 in by 5.954 in and it weighs 30 lb, so a single-person wall mount on unistrut or a masonry wall is realistic.
2) What kVAR do I actually get from the 17.5 kVAR UNIPAK if my system is 208V instead of 240V?
About 13.1 kVAR. The 17.5 kVAR rating on the 17X63PMURN is a 240V rating, and the correction factor for 208V service is 0.75, so 17.5 x 0.75 works out to 13.125 kVAR. Size your power factor correction off that number, not the nameplate, if you are on a 208V three-phase system.
3) Does this B-Line UNIPAK capacitor bank come with its own fuses or overcurrent protection?
No. The 17X63PMURN is the non-fused version, so there is no internal fusing and no disconnect included. You have to provide the branch circuit protection and a means of disconnect upstream per your local code, sized for a unit drawing 17.20A at up to 600V, three-phase. Plan that into the panel schedule before the unit lands on site.
4) Is this a fixed capacitor bank or does it switch stages automatically?
Fixed. The UNIPAK 17X63PMURN is a low voltage fixed capacitor bank, meaning it puts out its full 17.5 kVAR whenever it is energized. It suits a constant load such as a single large motor or a base load that runs continuously. If your plant load swings and you risk leading power factor at light load, you want an automatic switched bank instead, not this one.
5) What size conductors and breaker do I need to feed a 17.5 kVAR UNIPAK capacitor bank?
Start from the 17.20A rating on the 17X63PMURN. Capacitor circuits are normally sized above the rated current per NEC rules for capacitors, so the feeder and overcurrent device are picked off that 17.20A figure and your voltage, not off the kVAR number. The unit itself is non-fused, so all of that protection lives upstream.
6) Will the B-Line UNIPAK 17X63PMURN work on a 480V three-phase system?
The unit is rated to 600V, three-phase, so 480V is within its voltage rating. Note that the 17.5 kVAR figure is referenced to 240V, so the delivered kVAR on your system depends on the applied voltage. Confirm the operating voltage on the nameplate against your service before energizing.
7) What frame size is the 17X63PMURN UNIPAK, and how much wall space does it need?
It is an A2 frame. In real terms that is 22.3 inches by 8.5 inches by 5.954 inches, so it takes a narrow tall footprint on the wall with under six inches of depth. At 30 lb it does not need structural backing beyond normal anchors. Leave the working clearance your code requires in front of it.
