B-LINE 20023PMURF – Frequently Asked Questions
1) What kVAR does the B-Line 20023PMURF capacitor bank provide at 208V instead of 240V?
The 20023PMURF is rated 200 kVAR at 240V. Run it on a 208V system and you multiply the 240V kVAR rating by 0.75, so you get 150 kVAR of correction. Size your power factor calculation off that number, not the nameplate, or you will come up short on the correction you planned for.
2) Can the B-Line 20023PMURF UNIPAK capacitor bank be mounted outdoors?
Yes. The UNIPAK enclosure carries a NEMA 1, 3R rating, so it is suitable for indoor use and for outdoor rain and sleet exposure. The housing is 14 gauge steel with a powder coat finish, and the blown-fuse indicator lights sit behind a transparent weatherproof guard so you can read fuse status without opening the door in the weather.
3) What size 240V three-phase service is the 20023PMURF capacitor bank suited to?
It's a three-phase 240V unit rated 480A, so the feeder, disconnect and conductors serving it have to be sized for 480 amps. It is a fixed bank, meaning the full 200 kVAR is connected whenever it is energized, not switched in steps, so it belongs on a load with a steady baseline reactive demand rather than one that swings to light load.
4) How much space and support do I need to hang a 20023PMURF UNIPAK on a wall?
Plan for a cabinet measuring 36 in height, 24.36 in width and 22.298 in length, weighing 189 lb. That weight needs structural backing or unistrut, not drywall anchors, and leave working clearance in front per your local electrical code for a 480A, 240V piece of gear.
5) How do I know when a fuse has blown in the B-Line UNIPAK capacitor bank?
Three red neon blown-fuse indicating lights, one per phase, sit behind a transparent weatherproof guard on the enclosure. A maintenance tech walking the gear can see at a glance which phase has lost its fuse without opening the cabinet or metering the bank. Protection is three fuses and three lights, one set per phase.
6) What fuse protection is built into the 20023PMURF, and do I need separate fusing upstream?
The bank ships with three slotted blade type fuses rated at 200,000 ampere interrupting capacity, mounted on stand-off bushings or fuse blocks. Incoming line conductors land on solderless connectors, so hookup is a straight termination. The internal fusing is the capacitor protection; your upstream overcurrent device and disconnect are still sized and provided per your feeder design.
7) Is the 20023PMURF a switched or automatic power factor correction bank?
Fixed, not automatic. The UNIPAK 20023PMURF is a low voltage fixed capacitor bank, so all 200 kVAR is on the line whenever the unit is energized. That suits a motor load or plant bus with a constant reactive base. If your load varies widely and you risk leading power factor at night or on weekends, a fixed bank of this size is the wrong choice and you want an automatic stepped bank instead.
8) What does frame size E1 mean when ordering a B-Line UNIPAK capacitor bank?
E1 is B-Line's enclosure frame designation for the UNIPAK line, and on the 20023PMURF it corresponds to the 36 in by 24.36 in by 22.298 in cabinet. If you are matching an existing installation or standardizing mounting details across several banks, the frame size is the field to check against, since the same frame keeps footprint and mounting arrangement consistent.
