Automatic capacitor bank with 5 x 20 kVAR steps enables scalable power-factor correction as loads shift. This sequencing reduces reactive current and kilovolt-ampere demand, delivering measurable energy savings during peak hours. It is well-suited for facilities with fluctuating loads such as pumps, fans, conveyors, and machine tools. Three-phase 600 V rating and 96 A amperage ensure immediate compatibility with common industrial feeders. The 100 kVAR total output provides a robust correction profile for mid-size plants, improving voltage stability and equipment efficiency. The compact 11 in length by 2.5 in width and 2.5 in height wall-mount design saves valuable floor or rail space and simplifies installation. Optional molded-case circuit breaker rated 65 kAIC at 480/600 V offers enhanced protection and safer maintenance, while enabling seamless coordination with existing protective devices. The MCCB option reduces wiring complexity and improves fault isolation in crowded panel outfits. NEMA 3R weatherproofing (available) expands deployment to exterior equipment rooms or damp environments. UL Listed and CSA Certified ensure electrical safety and compliance in many jurisdictions, backed by Eaton's engineering support. The product ships with a standard one-year warranty from installation or eighteen months from shipment, underscoring long-term reliability. With Eaton AutoVAR 300, engineers gain a proven, drop-in PF correction solution that integrates with existing switchgear and delivers a clear ROI through energy and demand savings.

FAQs
The 100MCSR6313 is best suited for industrial environments with three-phase 600V feeders, where automatic power-factor correction is needed. Its wall-mounted design fits compact control rooms and equipment spaces, while the 5 x 20 kVAR stepping capability provides scalable correction as load profiles shift. Ideal applications include manufacturing lines, pumps and fans, conveyors, and data centers seeking to reduce reactive power and demand charges.
AutoVAR 300 sequences 5 x 20 kVAR steps to tailor reactive power correction to real-time loads. This fine-tuning minimizes overshoot and under-correction, delivering stable voltage and lower kVA demand. The result is more predictable energy consumption, improved equipment efficiency, and a quicker return on investment for facilities with variable load patterns such as seasonal manufacturing and peak-demand periods.
The unit is UL Listed and CSA Certified, signaling compliance with essential electrical safety standards. These certifications support safer installation practices and broader regulatory acceptance across regions. In addition, NEMA 3R weatherproofing (where specified) expands suitability for outdoor or damp environments, further safeguarding long-term reliability in varied operating conditions.
Plan for wall mounting using the J-frame with a compact footprint of 11 in length, 2.5 in width, and 2.5 in height. The system operates at 600 V three-phase and draws up to 96 A. An optional molded-case circuit breaker (65 kAIC at 480/600 V) can be added for enhanced fault protection and easier maintenance coordination with existing switchgear.
Expect a favorable ROI from improved power factor, reduced kW demand charges, and enhanced voltage stability, particularly during peak load periods. Maintenance is typically minimalāperiodic inspection of connections and enclosure integrity is recommended. The UL/CSA certifications and Eaton support, plus the optional MCCB, contribute to dependable long-term operation and predictable lifecycle costs.
