Eaton 150MCSR4313 Capacitor Bank - UL 508A 480V

The 150 kVA rating and 180 A current capacity enable precise reactive power compensation for 480 V three-phase loads, delivering targeted PF correction and reduced utility charges. By stabilizing voltage during motor starts and peak demand, the bank helps protect equipment and improve line efficiency in fans, pumps, and conveyors. The design supports straightforward integration with existing switchgear, minimizing control modifications while maximizing reliability. Tuning at 4.7 H provides a balanced response for a wide variety of load profiles, reducing over- or under-correction risks. This translates to predictable energy savings and easier procurement, as engineering teams can standardize on a single capacitor bank across multiple lines. Typical applications include retrofits in manufacturing, processing plants, and automation centers facing variable loads. Step X kVAR capability—3 x 50 kVAR increments—allows scalable compensation aligned with load growth, avoiding overcapitalization. Because operation requires a separate CT, the unit integrates cleanly with existing protection schemes and metering, supporting accurate monitoring and fault isolation. The enclosure is a powder-coated steel NEMA 1 cabinet designed for indoor wall mounting, with dimensions of 16 in depth, 36 in height, and 36 in width, and a 220 lb weight. This helps simplify site planning, reduces installation time, and supports code-compliant indoor installations. UL 508A, CSA Std. C22.2 No. 190, UL 810, and IEEE Std. 18 certifications underpin safety and performance, easing commissioning and ongoing maintenance. The product's compatibility with standard 480 V power systems and CT-based operation supports fast deployment, predictable ROI, and stronger compliance posture in regulated industries.
