FAQs
The 50MCSR231 is designed for wall-mounted installation in 240 V three-phase LV networks. Ensure proper clearance, verify control-interface compatibility with Eaton systems, and follow UL 508A wiring practices for switching and protection. Use appropriate fusing, grounding, and external disconnects per local codes. Confirm feeder capacity and short-circuit ratings match the installation to maintain reliability and safety.
With a 50 kvar rating at 240 V, the bank provides substantial reactive-power support to reduce line current and improve power factor. Expect measurable reductions in utility penalties and voltage drop across feeders, especially under peak load. Performance depends on system harmonics, motor loads, and existing PF; engineering studies help quantify exact gains.
Yes. The three-phase AutoVAR configuration suits multi-motor environments such as conveyors, pumps, and fans. By correcting PF at the source, it reduces current in feeders feeding these loads, stabilizes voltage, and improves motor efficiency. Ensure the kvar rating aligns with plant load profiles and harmonic conditions for optimal results.
The unit carries UL 508A, CSA Std. C22.2 No. 190, UL 810, and IEEE Std. 18 certifications. These standards validate electrical safety, control-panel suitability, and component reliability for industrial environments. Certification helps with supplier qualification, installation audits, and cross-site deployments without revalidating each site’s safety program.
Maintenance is minimal due to a solid, wall-mounted design and reliable switchgear integration. ROI comes from reduced energy penalties, lower feeder losses, and improved uptime through better voltage regulation. A site-specific energy audit can quantify payback by comparing pre- and post-installation energy costs and PF penalties.
