FAQs
Begin with verifying a three-phase 240V supply and ensure mounting on a suitable frame. Use the A2 frame with compatible enclosure mounting, and connect per the included wiring diagram. Since it is non-fused and available in NEMA 1 or NEMA 3R enclosures, place it in appropriate indoor or outdoor locations and perform commissioning with the factory spec sheet to confirm 7.5 kVAR rating at 240V.
The unit is a three-phase, low-voltage fixed capacitor bank rated for 240V, with an 18A operating current and a 7.5 kVAR reactive capacity. It employs UNIPAK construction and is designed for non-fused protection. Enclosures available include NEMA 1 and NEMA 3R, with a 14 gauge steel frame and powder-coated finish for durability.
Yes. It provides stable reactive power in three-phase 240V networks and supports critical loads typical of data centers. Use the 7X23PMURN for on-site PF correction, mechanical cooling load balancing, and to reduce penalties due to poor power factor, while noting the 240V kVAR rating and the 208V consideration noted in catalog notes (multiply 240V kVAR by 0.75 for 208V).
The capacitor bank is UL Listed and CSA Certified, signaling compliance with key electrical safety and performance standards. This certification simplifies audits, procurement approvals, and vendor qualification, while the NEMA 1/3R enclosure options provide proven protection for indoor and outdoor installations in regulated environments.
Expect energy savings from improved power factor and reduced utility penalties, along with longer equipment life due to stabilized voltages. The non-fused design reduces routine protection checks, and Eaton’s 1-year warranty from installation (or 18 months from shipment) provides assurance during the early service life while the durable powder-coated frame minimizes maintenance needs.
