Three-phase AutoVAR configuration uses switched-capacitor modules to deliver precise reactive power correction as load conditions evolve. This accelerates power factor improvement, reduces current draw, and helps stabilize voltage across motors and drives. It is well suited for manufacturing lines, process plants, and facilities with variable motor loads and intermittent AC loads. Safety, reliability, and compliance are built in. The 125MCSR231M carries UL 508A, CSA Std. C22.2 No. 190, UL 810, and IEEE Std. 18 certifications, simplifying procurement and regulatory reviews. This means fewer site objections and a faster path to operation in critical production spaces. Physical footprint and integration are designed for practicality. With a footprint of 14 in depth, 60 in height, and 36 in width, and a 367 lb weight, the unit mounts in standard electrical rooms and panels with minimal floor space impact. Its compatibility with the Eaton LV AutoVAR family enables scalable upgrades as load profiles shift. Installation and maintenance are straightforward. The switched-capacitor design reduces moving parts, enabling longer service intervals and lower maintenance costs. Operators benefit from smooth switching during load changes, avoiding voltage dips that can trip drives. For retrofits, pre-wired configurations and clear labeling simplify wiring and commissioning. Industry context and value: power factor correction at 240V with 125 kvar supports energy efficiency programs, reduces demand charges, and aligns with sustainability goals in manufacturing and processing facilities.
