FAQs
Begin by mounting the UNIPAK unit on a suitable frame within a compliant enclosure. Connect per the wiring diagram to the 480 V three-phase supply, ensuring the 9A rating is not exceeded. Install the three midget-type fuses and verify the neon-blow fuse indicators are visible behind the weatherproof guard. Confirm enclosure is appropriately rated (NEMA 1 or NEMA 3R) and secure all(terminals) connections before power-up.
Verify 480 V operation, three-phase configuration, and a 7.5 kVAR rating with a 9A current draw. Check enclosure suitability (NEMA 1 or NEMA 3R), frame size A1, and three fuses with 100,000 AIC. Use the catalog note to adjust kVAR for 208 V applications by multiplying the 240 V kVAR value by 0.75.
Yes. The 7X43PMURF Unipak delivers fixed reactive power in a three-phase 480 V setting, optimizing PF for motor drives, pumps, and conveyors. Benefits include reduced line losses, improved voltage profile, and enhanced equipment efficiency. Ensure proper coordination with existing reactive power sources and protective devices to avoid overcompensation.
The unit is UL Listed and CSA Certified, affirming compliance with safety and performance standards. These certifications facilitate regulatory approvals, supplier qualification, and safer maintenance practices in industrial facilities, while providing confidence in electrical isolation, enclosure integrity, and fuse protection essential for robust operation.
Maintenance is straightforward thanks to the neon indicators that signal blown fuses and the rugged powder-coated enclosure. The 1-year warranty (or 18 months from shipment) supports initial ROI, while energy savings from improved PF reduce utility bills and extend motor life. Regular inspection of fuses and indicators helps sustain performance and minimize unplanned downtime.
