Feature → Business Impact → Application: 90 A amperage rating paired with a 600 Vac / 250 Vdc voltage rating enables safe, scalable protection for typical PV string currents and mixed-voltage installations, reducing the need for multiple devices and lowering BOM cost. This translates to faster commissioning and improved system reliability for solar farms and commercial rooftop arrays. Feature → Business Impact → Application: Three-pole JG frame construction provides true three-phase protection, improving fault isolation and system uptime in utility-grade PV inverters and grid-connected systems. Feature → Business Impact → Application: Fixed thermal with adjustable magnetic trip (T185) supports precise coordination with other protection devices, enabling selective tripping and minimized downtime on solar DC and AC sections. Feature → Business Impact → Application: 65 kAIC at 240 Vac, 25 kAIC at 480 Vac, and 18 kAIC at 600 Vac interrupt ratings deliver high fault-current tolerance, reducing the risk of cascading failures in larger PV arrays and commercial installations. Feature → Business Impact → Application: Without terminals configuration provides installation flexibility for field wiring or downstream terminals, enabling seamless integration into existing panels and PV combiner boxes. Feature → Business Impact → Application: UL 489 certification and Series G PVGuard lineage offer proven compatibility with standardized electrical protection strategies, supporting compliance, easier buy-build decisions, and accelerated projects in industrial solar deployments.
