FAQs
The 175MCSR631W is a wall-mounted, three-phase capacitor bank rated for 600 V and 175 kvar, designed for straightforward integration into compatible switchgear or distribution panels. Ensure adequate enclosure space, clearance for connections, and adherence to UL 508A wiring guidelines. The unit’s dimensions (14 in depth, 36 in height, 36 in width) and 270 lb weight should be accounted for in the mounting plan and structural support. Engineer review is recommended for retrofit projects.
AutoVAR 300 provides rapid switching of capacitor banks to correct lagging power factor and reduce reactive current. By correcting PF closer to unity, facility loads draw less apparent power from the grid, lowering kVA demand and energy costs. This is especially effective for motors and drives in manufacturing lines, pumps, and HVAC systems where reactive energy consumption is high.
Yes. The 175MCSR631W is specifically engineered as a three-phase AutoVAR solution rated at 600 V. Its 175 kvar capacity supports substantial PF correction across large, multi-load facilities. The unit’s wall-mounted design is compatible with standard three-phase distributions, while its switched capacitor technology ensures fast response to changing load conditions and improved voltage regulation.
The 175MCSR631W carries UL 508A, CSA Std. C22.2 No. 190, UL 810, and IEEE Std. 18 certifications. These certifications indicate compliance with electrical safety, mechanical integrity, and performance standards essential for industrial environments. They support safer operation, simplify regulatory audits, and help ensure reliability in critical power factor correction applications.
Maintenance needs for a switched capacitor bank like AutoVAR are typically modest, focusing on periodic visual checks, connection integrity, and enclosure cleanliness. The ROI comes from reduced reactive power, improved power factor, and lower utility penalties over time. In data centers and manufacturing floors with high motor loads, the 175 kvar capacity can deliver measurable energy cost savings and enhanced equipment life.
