Feature → Business Impact → Application: The 250TPHSR231 uses a 601A amperage rating with a 250 kVAR (kilo-volt-ampere reactive) capacity, enabling precise, high‑quality power factor correction. This leads to lower utility penalties and improved motor efficiency, especially in facilities with variable loads like conveyors and pumps. Application-wise, its 60 Hz, 240V three‑phase configuration is ideal for mid‑market manufacturing sites looking to optimize energy use without extensive system redesign. Feature → Business Impact → Application: Heavy‑duty capacitor cells and fuse protection extend service life and reduce maintenance costs by isolating faults quickly, lowering the risk of unplanned outages. Application-wise, this supports continuous operation in process industries where uptime is critical. Feature → Business Impact → Application: Floor mounting in an NEMA 1 enclosure simplifies installation and service access, reducing footprint conflicts and enabling straightforward retrofit into existing electrical rooms. Application-wise, this is well-suited for upgrading legacy plants that require robust, code-compliant power factor correction. Feature → Business Impact → Application: Compatibility with AUTOVAR 600 family and 10 x 25 kVAR steps provides scalable energy optimization as loads grow, offering predictable budgeting and a clear upgrade path for facilities expanding their electrical systems. Application-wise, plants planning capacity expansion or new lines can align capacitor‑bank capacity with future demand.
