FAQs
Installation should accommodate a floor-mounted, single-door enclosure with an L-frame footprint of 26 in depth, 78 in height, and 38.5 in width. Plan for 852 lb weight and space for service clearances. The unit supports optional 65 kAIC MCCB protection and IQ 250 metering, simplifying integration with existing feeders and control systems.
The device is rated for 480A, at 480V, delivering a total 400 kVAR with 8 x 50 kVAR steps. It is a three-phase, floor-mounted system in an L-frame enclosure, designed for retrofit or new installations in industrial facilities with 480V power, enabling precise reactive power compensation and PF correction.
Yes. The 400TPCSR431 is CSA Certified and UL Listed, providing recognized safety and reliability for industrial environments. Optional protections include a molded-case circuit breaker rated 65 kAIC and digital metering (IQ 250), supporting regulatory compliance and robust energy management practices.
By delivering 400 kVAR of reactive support in 480V systems, the AutoVAR 600 improves power factor, reduces utility penalties, and lowers line losses. The granular 8 x 50 kVAR stepping allows load-tuned corrections, contributing to energy savings. ROI depends on base PF, load profile, and demand charges but typically justifies CAPEX in mid-to-large industrial facilities.
An optional IQ 250 digital metering module is available, enabling continuous monitoring of KVAr, voltage, current, and PF. This enhances asset visibility, supports proactive maintenance, and facilitates integration with energy management systems for data-driven optimization.
