Feature → Main breaker and fuses are integrated into the AutoVAR 600 capacitor bank, delivering built-in overcurrent protection and a safe, controlled shutdown during service. Business Impact → Reduces field wiring complexity and minimizes fault propagation, supporting higher uptime and faster commissioning. Application → Ideal for control panels, switchgear retrofits, and new builds where robust PF correction must align with 480 V three-phase distribution. Feature → Nine 50 kVAR steps (9 x 50 kVAR) enable precise, staged PF correction. Business Impact → Enables granular tuning to maintain target power factor across fluctuating loads, reducing penalties and improving transformer loading. Application → Suitable for manufacturing lines, data centers, and mixed-load environments requiring flexible var management. Feature → Rated for 480 V, 60 Hz, three-phase operation. Business Impact → Ensures immediate compatibility with common industrial feeders and minimizes retrofit risk. Application → Plug-and-play integration with existing plant electrical systems and new installations targeting standard 480 V distributions. Feature → NEMA 3R enclosure provides weather-resistant protection. Business Impact → Extends installation locations to indoor/outdoor spaces, lowering enclosure constraints and supporting maintenance access. Application → Suitable for plant rooms, outdoor bays, and facilities with challenging environmental conditions. Feature → Certifications include UL Listed, CSA Certified, UL 508A, and UL 810. Business Impact → Reduces compliance risk and simplifies procurement, installation, and inspection cycles. Application → Preferred choice for regulated environments and panel-building projects requiring formal safety approvals. Feature → Heavy-duty capacitor cells deliver robust reliability for long service life. Business Impact → Lowers life-cycle costs by reducing replacement frequency and maintenance downtime. Application → High-load PF correction in continuous operation scenarios across industrial facilities.
