Eaton 943PMURN LV Unipak Capacitor Bank - UL Listed CSA Certified
Part Number: 943PMURN
Quick Summary
The Eaton LV Unipak capacitor bank improves power factor for three-phase 480V systems. Facilities often grapple with wasted energy and higher demand charges when reactive power isn’t managed effectively. This unit carries UL Listed and CSA Certified safety marks, and it uses a robust NEMA 1/NEMA 3R enclosure suitable for indoor and outdoor installations. With upstream breaker or fuse protection, it integrates cleanly into existing switchgear, helping to stabilize voltage. By delivering 9 kVAR at 60 Hz and an 11 A rating, it translates to tangible reductions in energy waste and utility penalties while supporting smoother operation of motors and drives.

Eaton Specification Sheet - 943PMURN
Selling Policy 25-000 - Distribution and Control Products and Services
Feature → Business Impact → Application: The unit provides a 9 kVAR reactive power correction at 60 Hz with an 11 A rating for 480 V three-phase systems, enabling immediate power factor improvement and reduced energy losses in motor-driven processes and conveyors. This translates to lower utility demand charges and enhanced process stability in manufacturing environments, feeding into lower total cost of ownership and longer equipment life. Feature → Business Impact → Application: Its NEMA 1 and NEMA 3R enclosure (14 gauge steel with durable powder coat) delivers indoor and outdoor protection, reducing field rework and enabling reliable operation across harsh environments in food and beverage, water treatment, and industrial facilities. Feature → Business Impact → Application: Upstream breaker or fuse protection simplifies integration with existing switchgear, minimizes install time, and reduces wiring complexity during retrofit projects or new builds. Feature → Business Impact → Application: Documentation, including UL Listed and CSA Certified status, aligns with compliance programs and procurement standards, while the compact footprint (5.254 in depth) eases rack and enclosure planning for tight spaces. In practice, designers leverage the 60 Hz rating to support accurate voltage and phase balance in variable-speed drives, improving overall efficiency and system reliability. Feature → Business Impact → Application: Practical notes, such as the 240V to 208V kVAR conversion (multiply by 0.75), help engineers plan exact compensation for mixed-voltage networks common in multi-site facilities.

FAQs
The 943PMURN requires an upstream breaker or fuses, enabling seamless integration with standard switchgear. This compatibility simplifies retrofits by matching common electrical protections and reduces wiring complexity, helping project teams meet installation schedules without sacrificing safety.
Key specs include a 9 kVAR rating at 60 Hz, an 11 A amperage, and a 480 V three-phase configuration. The enclosure supports indoor and outdoor use (NEMA 1, NEMA 3R), and the unit is designed to operate with 240V to 208V adjustments as needed for PF corrections across sites.
Yes. The 943PMURN uses an enclosure rated for both indoor and outdoor environments (NEMA 3R compatible), with a durable powder-coated steel housing. This makes it appropriate for weather-exposed areas such as outdoor service yards and protected rooftop installations in industrial facilities.
The unit is UL Listed and CSA Certified, ensuring compliance with North American electrical safety standards. These certifications help procurement meet regulatory requirements, support safer commissioning, and simplify qualification during audits and supplier qualification programs.
The 943PMURN is covered under Eaton's warranty policy (25-000): one year from installation or eighteen months from shipment, whichever occurs first. This warranty reduces maintenance risk and provides a predictable ROI when combined with energy savings from improved power factor and reduced utility charges.
