UNIPAK three-phase low-voltage capacitor banks deliver precise power factor correction with a compact C1 frame. In this model, 85 kVAR is available at 600 V and 83.3 A, enabling targeted reactive power reduction. This translates to lower utility demand charges and improved motor efficiency across industrial processes such as pumping, compression, and extrusion. Protection and visibility are enhanced by three fuses with 200,000 AICC and red neon indicating lights behind a weatherproof guard, reducing downtime and speeding fault diagnosis during maintenance windows. The enclosure combines NEMA 1 and NEMA 3R options in a rugged 14-gauge steel chassis with a durable powder coat, supporting retrofit or new installations in varied environments. Frame size C1 keeps footprint minimal while maximizing ease of integration with existing switchgear. Certifications and warranty—CSA, UL, and a one-year policy—provide compliance confidence and predictable service. Operationally, the bank lowers reactive power consistently, supports voltage stability under dynamic loads, and improves reliability for motors, drives, and HVAC systems. For installers, the three-slottedblade fuses and straightforward wiring minimize panel disruption and speed commissioning. A practical catalog note clarifies kVAR sizing for 208V systems by applying a 0.75 factor to the 240V rating, helping engineers optimize capacitor banks for mixed-voltage facilities.

FAQs
Installation should begin with de-energizing the panel and verifying compatibility with a three-phase 600 V system. Mount the UNIPAK unit in a NEMA 1 or NEMA 3R rated section, secure the 14-gauge steel enclosure, and connect the three-phase leads and protective fuses as specified. Use the neon indicators to verify fuse status after wiring, and confirm 83.3 A current rating and 85 kVAR capability are suitable for the target load. Ensure clear labeling and proper clearance around the unit for heat dissipation and service access.
Key specs include three-phase operation, 600 V voltage rating, 83.30 A amperage, and a nominal 85 kVAR reactive power rating. The unit uses three slottedblade-type fuses with 200,000 AICC and provides red neon fault indicators. The enclosure supports NEMA 1 and NEMA 3R, with a C1 frame, designed for low-voltage fixed capacitor bank applications in industrial facilities.
Yes. It is a low-voltage fixed capacitor bank intended for three-phase systems to improve power factor, reduce reactive power, and lower energy costs. Its 85 kVAR rating at 600 V makes it suitable for motor-heavy loads and drives. For 208 V applications, size adjustments use the catalog note multiplying the 240 V kVAR by 0.75. UL and CSA certifications support compliance needs.
The 8563PMURF is CSA Certified and UL Listed, indicating compliance with recognized safety and performance standards. These certifications help meet regulatory requirements for industrial installations, provide assurance to procurement and safety teams, and facilitate insurance and warranty processes. A one-year warranty from Eaton further supports long-term reliability and service.
Maintenance focuses on fuse integrity and visual indicators. Regularly inspect the three slottedblade fuses for signs of wear and verify the neon indicators reflect proper operation. Ensure enclosure access is unobstructed and panels remain properly sealed in accordance with the NEMA rating. Plan replacements in line with Eaton’s warranty terms, and document performance changes to track energy savings and return on investment.
