FAQs
The 100MCSR4313W is designed specifically for 480V three-phase power distribution. It is a wall-mounted AutoVAR capacitor bank rated at 100 kvar, with a compact footprint (14 in depth, 36 in width and height) and a 220 lb weight, enabling straightforward integration with standard Eaton control interfaces and existing electrical distributions.
AutoVAR continuously monitors load conditions and automatically adjusts reactive power; this reduces reactive kVAr draw, lowers utility penalties, and stabilizes voltage during load fluctuations. It is particularly beneficial for motors, presses, and other high-demand equipment common in manufacturing environments, delivering measurable energy savings over time.
This capacitor bank carries UL 508A and UL 810 certifications, CSA Std. C22.2 No. 190, and IEEE Std. 18, confirming electrical safety, enclosure integrity, and performance for industrial control equipment. These approvals simplify procurement and support regulatory compliance for regulated facilities.
Plan for a wall-mounted unit with dimensions of 14 in depth by 36 in width and height, and an approximate weight of 220 lb.
