FAQs
The 350TPCSR431 is designed for three-phase, 480V systems with a floor-mounted enclosure. Its 7 x 50 kVAR steps allow precise correction for varying loads, and the unit’s L-frame, single-door enclosure simplifies installation in retrofit projects or new builds while preserving access for maintenance.
Key specs include a 350 kVAR rating, 420A amperage rating, 480V three-phase operation, floor mounting, L-frame enclosure, and 7 x 50 kVAR step blocks. Optional features are a molded-case circuit breaker rated 65 kAIC at 480/600V and IQ 250 digital metering.
The unit carries CSA Certified, UL Listed, UL 508A, CSA Std. C22.2 No. 190, UL 810, and IEEE Std. 18, providing regulatory alignment for industrial control panels, safety compliance, and reliable electrical performance in commercial facilities.
By delivering targeted reactive power (350 kVAR) at 480V, the AutoVAR 600 improves power factor, lowers apparent power, and reduces utility demand charges. This is especially beneficial for facilities with heavy motor loads and variable demand, delivering measurable operating-cost savings.
Plan for floor mounting in a sturdy enclosure, accounting for the 808 lb weight. Consider the optional IQ 250 metering for ongoing energy monitoring, and the 65 kAIC MCCB option for future circuit protection upgrades. Regular inspection of connections and conditioning of the metering electronics will support long-term reliability.
