Eaton 350TPHSR631M Switched Capacitor Bank - UL Listed

Flexible VAR stepping and a high-capacity rating support precise power factor correction for varying load profiles. The 7 x 50 kVAR steps provide a total of 350 kVAR, enabling staged compensation that reduces reactive power charges and improves voltage stability across plant feeders. This level of control helps maintain motor efficiency, extends equipment life, and minimizes disturbances during startup and dramatic load swings. An integrated main breaker option with fuse protection simplifies wiring, speeds commissioning, and enhances safety during maintenance. The enclosure consolidates protective devices in one location, reduces panel count, and improves arc-flash compliance. Maintenance routines become more predictable, with straightforward fault isolation and quick replacement of protective fuses. Designed for three-phase, 600 V systems at 60 Hz, the unit aligns with common industrial feeders and supports scalable upgrades. Its compatibility with AUTOVAR 600 enables straightforward expansion as facility loads grow, protecting existing investments and avoiding early equipment obsolescence. Field-adjustable kVAR steps support evolving process demands without a full system rebuild. The enclosure is a floor-mounted, L-sized NEMA 1 cabinet housing heavy-duty capacitor cells for durability in manufacturing environments. With dimensions of 29 in depth, 41.3 in width, and 80 in height, and a weight of 843 lb, it seats comfortably in floor space while preserving service access for routine maintenance and part replacements. UL Listed and CSA Certified provide regulatory assurance for safety and reliability, backed by Eaton's warranty policy of one year from installation or eighteen months from shipment. The product supports compliance documentation, with installation guides and field support from Eaton to minimize project risk and downtime. From a control-system perspective, the AutoVAR bank integrates with plant protection schemes and supports staged switching to minimize power quality disturbances. Operators benefit from predictable capacitor switching, reduced voltage dips, and clearer diagnostics for faster fault localization in case of an EV or motor start surge. Cost of ownership is lowered through reduced reactive power penalties and longer capacitor life thanks to robust cell design and protective fusing. The 600 V system also reduces conductor sizing and insulation costs on new builds, while the modular 7x50 kVAR scheme enables phased capital expenditure aligned to project budgets.
