PVGuard DC/AC protection is integrated into a complete molded case breaker. This design minimizes protection gaps across DC PV strings and AC distribution, boosting system reliability and uptime. Ideal applications include solar arrays, inverter rooms, and combiner boxes in commercial and utility-scale installations. High interrupt ratings across multiple voltages provide a wide protective margin. The device delivers 65 kAIC at 240 Vac, 35 kAIC at 415/480 Vac, and 18 kAIC at 600 Vac, enabling safe operation under fault conditions. This supports utility-grade PV deployments and reduces equipment damage risk. 600 A amperage rating paired with a 600 Vac rating supports large PV string currents and heavy AC feeders. This reduces the need for parallel devices and simplifies protection planning, saving material and installation time. Applications include utility-scale infeed points and commercial rooftops with dense arrays. Trip Type T185 ensures a fast, predictable response to short circuits and arc faults, improving safety margins and reducing nuisance trips in dynamic PV environments. LG frame and three-pole configuration deliver a robust, standard form factor that matches common MCCB enclosures. The complete breaker frame simplifies replacement in existing switchgear and reduces field adaptation time. Terminals are without terminals, enabling clean, busbar-friendly field wiring. UL 489 certification confirms compliance with a globally recognized safety standard for molded case breakers. A 25-000 Eaton policy provides one year from installation or 18 months from shipment, whichever occurs first, reducing lifecycle risk and enabling proactive maintenance planning. Compact dimensions of 5.48 in length, height, and width and a modest 13.5 lb weight facilitate mounting in constrained spaces and speed up installation. This combination of form factor and LG frame supports quick upgrades and straightforward stocking for field service teams.
