FAQs
Installation should begin with verifying floor loading and providing dedicated space for access to low-voltage terminations, lugs, and the integrated main breaker option if selected. The AutoVAR 600 is floor-mounted and measures 29 in deep, 41.3 in wide, and 80 in high, weighing about 1104 lb, requiring proper handling equipment and compliant enclosure clearances.
The 11 stepped 50 kVAR increments allow staged reactive power compensation, smoothing load changes and reducing voltage dips. The result is a higher power factor, lower utility penalties, and better motor efficiency. This makes it well-suited for automotive, manufacturing, and distribution facilities with fluctuating electrical demand.
Yes. Designed for low-voltage (600 V) three-phase systems, the Eaton 550TPHSR631M integrates with AUTOVAR 600 and provides reliable reactive power support. Its rugged floor-mount design and NEMA 1 enclosure handle demanding factory environments, helping keep motors running efficiently and reducing electrical stress.
The unit is UL Listed and CSA Certified, signaling compliance with recognized safety and performance standards. For procurement, these certifications mitigate supplier risk, simplify qualification processes, and support any regulatory or corporate supplier requirements in regulated industries.
Plan for routine inspection of fusing protection and electrical connections, plus periodic verification of the main breaker option if chosen. The warranty covers one year from installation or 18 months from shipment. ROI benefits come from energy savings, reduced voltage disturbances, and extended motor life through reliable reactive power management.
