Feature → Business Impact → Application: The AUTOVAR 300 provides automatic capacitor banking for three-phase 600 V systems, delivering 50 kVAR at 48 A in a compact wall-mount enclosure. This directly improves power factor, reduces utility penalties, and lowers heat losses in motors and drives—benefits that translate into measurable energy savings for medium-to-large facilities. Application: Ideal for manufacturing floors and process plants where variable motor loads and motor starting contribute to reactive power and voltage fluctuations. Feature → Business Impact → Application: Optional molded-case circuit breaker rated 65 kAIC at 480 V and 600 V enhances fault protection within control panels, reducing downtime risk and simplifying compliance during maintenance. Application: Critical for panels servicing motors, conveyance systems, and heavy automation that require robust overcurrent protection. Feature → Business Impact → Application: NEMA 3R weatherproofing enables reliable outdoor or harsh-indoor installation, extending the product’s usable footprint and reducing enclosure needs. Application: Outdoor equipment pads, exterior wall-mounts, and protected indoor environments. Feature → Business Impact → Application: The unit’s six-spec footprint—14 in depth, 36 in height, 36 in width, and 200 lb weight—facilitates installation planning and ensures compatibility with existing enclosures. Application: Retrofit projects and new builds where space planning is critical. Feature → Business Impact → Application: Industry-standard certifications UL Listed, CSA Certified, UL 508A, UL 810, and IEEE 18 provide compliance confidence for panel builders and end users. Application: Projects with strict electrical codes or customer QA requirements. This combination supports faster procurement cycles and more predictable maintenance budgets.

FAQs
The unit is designed for wall mounting with a 600 V rating and 48 A capacity. Ensure a sturdy wall, adequate clearance for ventilation, and compatibility with a 14 in depth, 36 in width and 36 in height cabinet footprint. Use proper electrical enclosure fittings, secure mounting hardware, and connect to a protective MCCB if configured. Follow UL and CSA guidelines during installation and verify NEMA 3R weatherproofing suitability for the chosen location.
Key specs: 50 kVAR rating, 48 A, 600 V, three-phase, and 5 x 10 kVAR steps in a J-frame. These specs enable effective PF correction for moderate-to-large motor loads, reducing current distortion and improving voltage profiles. The optional 65 kAIC MCCB enhances fault protection, supporting safer, more reliable operation in demanding environments.
Yes. With a 50 kVAR rating and 600 V three-phase configuration, it is well-suited for mid-to-large industrial facilities and data centers that require consistent power-factor correction and voltage stability. The wall-mount form and NEMA 3R weatherproofing support diverse installation scenarios, including retrofit projects in existing facilities.
This unit carries UL Listed, CSA Certified, UL 508A, UL 810, and IEEE Std. 18. These certifications address safety, electrical-code compliance, panel integration, and performance expectations, simplifying procurement and reducing validation time in regulated environments.
Eaton offers a standard warranty of one year from installation or eighteen months from shipment, whichever occurs first.
