FAQs
The 50MCSR4313W is designed for wall-mount installations with a 3R enclosure, offering a compact footprint of 40 in W x 45 in H x 40 in D and a weight of 283 lb. Ensure adequate mounting studs, clearances for service access, and proper ventilation near the control area. Verify downstream bus connections align with your 480 V distribution setup and follow applicable wiring practices per the Eaton specification sheet.
Key specs include a 480 V operating voltage, 50 kvar reactive power capacity, wall-mounted 3R enclosure, and a cabinet footprint of 40 in x 40 in x 45 in with a 283 lb weight. The unit is a switched capacitor bank designed for automatic reactive power compensation and is CSA Certified and UL Listed for safety and compliance.
Yes. With a 50 kvar rating and 480 V operation, the AutoVAR 300 is well-suited for motor loads, drives, and lighting in manufacturing, process plants, and HVAC systems. Its switched capacitor design enables staged correction, improving power factor, reducing current in feeders, and supporting voltage stability across varying load conditions.
The 50MCSR4313W carries CSA Certification and UL Listing, indicating compliance with rigorous safety, performance, and quality standards. This is important for procurement, regulatory audits, and reliability in controlled environments, particularly in industries subject to strict vendor qualification and safety requirements.
Expected ROI comes from energy savings and demand-charge reductions achieved by improved power factor. Maintenance is typically limited to periodic inspection of switchgear contacts, capacitors, and enclosure integrity, aided by Eaton’s specification documentation. The robust 3R enclosure and wall-mount design reduce field maintenance concerns while supporting long service life in demanding industrial environments.
