FAQs
The 200MCSR431W is a wall-mounted, three-phase capacitor bank designed for 480V systems. It installs in retrofit or new builds with standard enclosure clearances and Eaton wiring diagrams. Its compact footprint and metric-friendly dimensions support quick integration into existing panels while maintaining safe access for service personnel.
With a 200 kvar rating, this AutoVAR bank provides targeted reactive power compensation to uplift the system PF under varying loads. Actual PF improvement depends on the load profile, but facilities typically see a reduction in kVA demand and better voltage stability on main feeders, decreasing penalties and transformer loading.
The unit carries UL 508A and CSA certifications, and it complies with UL 810 and IEEE 18 standards. These certifications ensure electrical safety, protection of personnel, and reliable performance in industrial environments, supporting compliance with regional electrical codes and safety programs.
Installation leverages a wall-mount design with accessible wiring points and clear documentation, reducing commissioning time. Maintenance is straightforward, involving periodic inspection of electrical connections, housing integrity, and ensuring venting paths remain unobstructed. Routine checks help sustain performance and extend capacitor bank life with minimal downtime.
ROI typically stems from reduced reactive power charges and improved transformer efficiency. By lifting the power factor, facilities can lower kVA demand, reduce energy losses, and extend the life of upstream equipment. Exact payback depends on load profiles, utility tariffs, and current PF levels, but energy cost reductions are a primary driver for the investment.
