FAQs
The 150MCSR431M is designed for 480V three-phase systems with a wall-mount enclosure, making it suitable for retrofit and new installations. Its dimensions (14 in depth, 60 in height, 36 in width) and 300 lb weight support secure, space-conscious integration into standard electrical rooms. It connects to standard control circuits and can be incorporated into existing power-factor correction schemes without extensive rearrangement.
The unit carries UL 508A, CSA Std. C22.2 No. 190, UL 810, and IEEE Std. 18 certifications. These mark compliance with safety, electrical installation, and product performance standards, reducing procurement risk, simplifying audits, and ensuring reliable operation in industrial environments where strict regulatory adherence is required.
At 480V, the AutoVAR 300 provides 150 kvar of reactive power compensation, delivering significant power-factor improvement for motors and non-linear loads. This correction reduces current draw, lowers utility penalties, and stabilizes voltage on feeders feeding critical equipment, improving overall system efficiency and equipment longevity.
Installation is designed for wall-mount use in appropriate electrical rooms or enclosures. The compact footprint (14 in x 36 in x 60 in) and 300 lb weight allow straightforward integration with nearby switchgear or panels, minimizing additional enclosure needs while maintaining safe clearances and compliance with UL 508A and UL 810 requirements.
Expect a favorable payback from energy-cost reductions due to improved power factor, reduced reactive penalties, and potential utility incentives. Maintenance is generally straightforward—periodic inspection of connections, enclosure integrity, and capacitor health; Eaton’s design supports long service life, with straightforward replacement of banks or modules as part of standard preventive maintenance.
