Eaton JGEDC3250FAW PV Guard MCCB - UL 489

The 250 A amperage rating delivers robust current handling for large PV strings, reducing the risk of nuisance trips and optimizing bus performance in commercial installations. This translates to measurable business value through improved system uptime and a lower total cost of ownership, especially in grid-tied solar facilities where outages directly impact energy production. The device’s 600 Vac / 250 Vdc voltage ratings expand compatibility across AC and DC sections of PV plants, enabling a single protective solution across inverters, combiner boxes, and main distribution. With a fixed thermal trip and adjustable magnetic trip (Trip Type T185), you gain precise overcurrent coordination and rapid response to surges typical of PV environments, enhancing safety and equipment longevity. The JG frame, paired with a complete breaker design and terminals-less configuration, simplifies installation and reduces field wiring complexity, cutting commissioning time and labor costs. An interrupt rating of 35 kAIC at 600 Vac provides strong fault-current withstand, supporting higher fault currents common in utility-scale configurations. UL 489 certification confirms code compliance, while the compact form and 6.5 lb weight support straightforward mounting and serviceability in tight electrical rooms. Finally, Eaton’s PV Guard lineage ensures ongoing reliability and access to product support, helping maintenance teams plan preventive actions and minimize unplanned downtime.
