Feature → Business Impact → Application: The UNIPAK design consolidates components into a compact footprint, reducing floor space and simplifying installation in tight electrical rooms. This translates to lower upfront and ongoing maintenance costs for facilities, controls engineers, and procurement teams. Use this low voltage fixed capacitor bank in manufacturing lines and data centers to improve power factor, minimize utility penalties, and extend motor life. Feature → Reliable, non-fused protection improves maintenance intervals and reduces routine replacements, enabling easier service during planned outages and reducing downtime risk in critical processes. Use in three-phase systems with 480 V to maintain stable voltage profiles across drives and motors. Feature → 14 gauge steel enclosure with powder coat finish provides rugged, corrosion-resistant protection, supporting long service life in harsh environments and helping facilities meet maintenance and compliance standards. Feature → NEMA 1 and NEMA 3R enclosures offer indoor and outdoor installation flexibility, allowing adjacent outdoor equipment or protected indoor spaces to house the capacitor bank without extra housings. Feature → Frame size C1 and compact dimensions (10.6 in depth, 12.1 in width, 26.3 in height) enable straightforward replacement in existing racks and enclosures, reducing retrofit complexity and downtime. Feature → 70 kVAR rating with 84 A capacity delivers predictable reactive power correction for fast payback in energy-intensive operations, supporting measurable efficiency gains and improved voltage stability across the plant. Feature → UL Listed and CSA Certified provide third-party safety validation, ensuring regulatory compliance and helping procurement meet corporate governance standards for electrical assemblies.

FAQs
The 7043PMURN is a three-phase, 480 V fixed capacitor bank designed for integration into standard low-voltage electrical rooms. With a C1 frame, 14 gauge steel enclosure, and non-fused protection, it fits most retrofit scenarios and mirrors common LV switchgear footprints. Before installation, confirm enclosure space, mounting orientation, and bus arrangement to ensure clean integration and minimal downtime.
Key specs include 70 kVAR reactive power rating, 84 A amperage, and 480 V three-phase operation. This combination delivers predictable PF correction, reducing reactive power charges and improving voltage stability. In practice, facilities see lower utility penalties, steadier motor voltage, and extended equipment life in drives and compressors when deployed in appropriate loads.
Yes, the unit supports indoor and outdoor applications via NEMA 1 and NEMA 3R enclosure options, offering corrosion resistance and weather protection. For outdoor deployments, ensure proper mounting clearances and drainage, and verify ambient conditions align with installation guidelines to maintain reliability and reduce maintenance needs.
The bank is UL Listed and CSA Certified, signaling conformance with recognized safety and performance standards for electrical equipment. These certifications aid procurement and compliance audits, giving engineers confidence in electrical integrity, fire safety, and reliability across industrial environments.
With a 70 kVAR rating and 84 A capacity, PF correction reduces reactive power charges, delivering faster payback in energy-intensive operations. Maintenance is typically low due to non-fused protection and robust 14-gauge steel construction; however, plan regular inspection of enclosure integrity, wiring connections, and mounting hardware per Eaton’s guidelines to maximize uptime.
