FAQs
The 125MCSR4313MW is a wall-mounted, three-phase switched capacitor bank designed for 480V systems. Its 14 in depth, 36 in width, and 60 in height footprint, plus a 310 lb weight, support retrofit installations within standard electrical rooms. The unit’s 3R enclosure and UL/CSA certifications simplify integration with common panel schedules and control schemes.
Key specs include 480V three-phase input, 125 kvar reactive power rating, AutoVAR technology, wall-mounted 3R enclosure, and a footprint compatible with mid-size electrical rooms. Certifications include UL 508A, CSA Std. C22.2 No. 190, UL 810, and IEEE Std. 18, all supporting safe, reliable operation in industrial environments.
The unit carries UL 508A, CSA Std. C22.2 No. 190, UL 810, and IEEE Std. 18. These certifications validate electrical safety, construction quality, enclosure integrity, and performance under defined electrical standards, aiding regulatory compliance, insurance requirements, and reliability in manufacturing or utility-driven facilities.
Best used in industrial facilities with significant motor loads, data centers, and large commercial buildings where reactive power compensation improves power factor and reduces penalties. Applications include HVAC systems, pumps, conveyors, and metal or chemical processing lines, where stable voltage and improved efficiency drive lower operating costs.
The AutoVAR capacitor bank is designed for low-maintenance operation, with most ROI realized through PF improvement and penalty reductions rather than routine servicing. Quick installation and integration with existing control schemes shorten project timelines, while certified components and wall-mounted design support long-term reliability and scalable energy-management initiatives.
