UNIPAK fixed capacitor bank design reduces wiring complexity and panel footprint, accelerating installation and serviceability. With fewer interconnections and a compact A1 frame, technicians can route feeders more efficiently and complete commissioning faster. In retrofit and new-build applications, this translates to lower labor costs and shorter project schedules. High-capacity, compact performance: the unit is rated 9A at 480V three-phase, delivering 7.5 kVAR of reactive-power correction. This precise PF support minimizes voltage drop on shared feeders, reduces current in large motors and compressors, and helps avoid penalties from utility demand charges. It sits well in manufacturing lines, packaging, and process facilities. Protection and enclosure design: Non-fused protection simplifies maintenance while reducing nuisance trips, and the NEMA rated enclosure supports diverse environments. The cabinet uses 14 gauge steel with a durable powder coat, ensuring corrosion resistance in harsh plant surroundings. The combination of rugged enclosure and simple wiring reduces service events and extends mean time between failures. Certification and compliance: UL Listed and CSA Certified provide safety assurances for panel builders, contractors, and end users, easing procurement and ensuring regulatory alignment. The A1 frame and powder-coated finish align with industry expectations for low-voltage capacitor banks, while the 480 V three-phase rating matches common electrical distributions in plant floors. Installation and compatibility: The UNIPAK family is designed for straightforward mounting in standard control panels and switchgear footprints, simplifying BOM planning and spare-part compatibility. Catalog notes help designers compute 208V kVAR from 240V values for accurate sizing, supporting proactive project scoping and predictable performance. In summary, this unit delivers reliable power-factor correction with minimal installation friction and robust safety certifications, supporting energy savings and uptime.
