Eaton 200MCSR431 LV AutoVAR 300 - CSA/UL
Part Number: 200MCSR431
Quick Summary
Eaton LV AutoVAR 300 capacitor bank is an automatic reactive power manager for 480 V three-phase electrical systems. Facilities face rising energy costs and voltage fluctuations that strain equipment and spike utility charges. This solution addresses that by automatically coordinating capacitor stages to maintain a stable power factor. It carries CSA Certified and UL Listed safety certifications, and its NEMA 3R weatherproof enclosure supports outdoor or rugged indoor installations. By integrating with existing switchgear, it reduces energy penalties, improves motor efficiency, and simplifies procurement with a wall-mounted, modular design.

Automatic VAR control: The AutoVAR 300 continuously manages reactive power to maintain a near optimal power factor, delivering measurable energy savings and reducing utility penalties for large facilities. In real-world installations such as manufacturing plants and data centers, this translates to lower operating costs and improved voltage profiles. High-capacity staged design: With 200 kVAR total and 5 x 40 kVAR stages, the system can fine-tune compensation to changing load conditions, minimizing over and under correction. This is ideal for processes with variable loads and for retrofits into existing 480 V three-phase networks. Safety and installation: Optional molded-case circuit breaker rated 65 kAIC at 480 V and 600 V, plus NEMA 3R weatherproofing, wall mounting, and code-compliant enclosure design simplify outdoor installation while maintaining electrical safety. Physical specs and compatibility: 241 A amperage rating, 14 in depth, 36 in height and width, with a 270 lb weight, align with standard Eaton switchgear footprints for easy retrofit or expansion. Warranty and service: Eaton provides a one year warranty from installation or eighteen months from shipment, aiding maintenance planning and asset lifecycle management.
