Feature → Business Impact → Application: Three-phase 480V AutoVAR design enables rapid, precise reactive power correction, improving power factor and reducing kVA demand on the grid. This translates to lower utility penalties and reduced heat losses in motor systems, especially in manufacturing lines or batch processing facilities. Application: Use in switchgear enclosures and motor control centers to stabilize voltage and improve overall efficiency. Feature → Business Impact → Application: 100 kvar capacity provides scalable compensation for growing loads, supporting future expansion without replacing the bank. This reduces capital expenditure and downtime during upgrades. Application: Suitable for data centers and automation facilities where load growth is anticipated and reliability is critical. Feature → Business Impact → Application: Wall-mounted enclosure simplifies installation and service access, shortening commissioning times and reducing space requirements. This leads to faster project timelines and easier routine inspections. Application: Ideal for retrofit projects in existing plant rooms and compact control panels. Feature → Business Impact → Application: UL 508A, CSA C22.2 No. 190, UL 810, and IEEE 18 compliance minimize regulatory risk and streamline safety approvals. This supports facility standards and maintenance programs. Application: Compliance-focused deployments in regulated environments such as food & beverage, pharma, and heavy manufacturing. Feature → Business Impact → Application: Integrated with the AutoVAR family for consistent performance, predictable maintenance, and simplified spare-part management. This reduces total cost of ownership and extends system uptime. Application: Broad applicability across industrial automation, OEM panels, and power management retrofits.

FAQs
The unit is designed for wall mounting in compact control rooms or switchgear compartments. Its dimensions are 14 in (depth) by 60 in (height) by 36 in (width), and it weighs 270 lb, enabling straightforward installation alongside other 480V equipment without extensive structural modifications.
Yes. It is built for 480V three-phase networks and delivers 100 kvar of reactive power. This capacity supports substantial power factor correction for mid-to-large industrial loads, reducing apparent power and improving voltage stability across critical equipment.
The product carries UL 508A, CSA Std. C22.2 No. 190, UL 810, and IEEE Std. 18 certifications, ensuring compliance with electrical safety, enclosure, and control standards suitable for industrial environments and switchgear installations.
By improving power factor toward near unity, facilities typically reduce kVA charges, lower line losses, and improve motor efficiency. ROI improves with load growth and uptime, as fewer penalties and reduced heat load translate into energy cost savings and extended equipment life.
Schedule periodic visual inspections, verify enclosure integrity, and test electrical connections as part of routine maintenance. The UL and IEEE certifications support ongoing reliability, while the modular AutoVAR design simplifies part replacement and reduces downtime during servicing.
