FAQs
Yes. The 943PMURF is a three-phase, 480 V low-voltage fixed capacitor bank designed to retrofit into standard industrial panels. It uses an A1 frame and NEMA 1/NEMA 3R enclosure, aligning with common Eaton and customer panel configurations. The unit includes three fuses and status lights, which simplifies integration and ongoing maintenance within existing electrical assemblies.
The 943PMURF provides a 9 kVAR rating with an amperage of 10.80 A, enabling meaningful power factor correction in moderate to heavy motor loads. By supplying leading reactive current, it reduces reactive power demand from the supply, lowers utility penalties, and improves overall system efficiency in 3-phase networks typical of manufacturing and process environments.
Absolutely. Its UNIPAK design, 480 V three-phase operation, and 9 kVAR rating make it well-suited for motor-driven applications in manufacturing, pumps, conveyors, and HVAC systems. The rugged enclosure and protective fuses support reliable operation in harsh plant settings, while the compact footprint eases retrofit into space-constrained panels.
The 943PMURF is UL Listed and CSA Certified, two critical indicators of compliance with safety and performance standards for industrial equipment. These certifications facilitate regulatory acceptance, safer installation, and streamlined maintenance planning across facilities that require dependable, certified components for power factor correction.
Maintenance is straightforward: monitor the three fuse protections and indicator lights, perform periodic visual inspections, and verify enclosure integrity. The 943PMURF can lower energy costs by reducing reactive power, improve motor efficiency, and mitigate penalties from poor PF, delivering a favorable ROI in retrofit projects and new installations with long service life under a powder-coated steel enclosure.
