Eaton RGHDC3300FFWE PV Guard - 125 kAIC at 240 Vac

Three-pole RG-frame design provides coordinated protection across three-phase PV circuits, simplifying panel layouts and improving fault containment in commercial rooftops and solar farms. This reduces system-wide outages and speeds field commissioning by aligning with standard RG frame installations. The 3000 A amperage rating supports large PV arrays, minimizing nuisance trips and eliminating premature upgrades as systems scale in capacity. With a voltage rating of 600 Vac and 250 Vdc, this MCCB covers both AC and DC protection paths commonly found in PV inverters and combiner boxes, enabling a compact, single-device solution and reducing part counts. The fixed thermal and magnetic trips (Trip Type T186) ensure fast, predictable response to overloads and short circuits, improving safety margins in high-current environments and protecting critical equipment. An interrupt rating of 125 kAIC at 240 Vac and 65 kAIC at 480 Vac provides robust fault clearance for diverse grid conditions, minimizing fault energy transferred to panels and inverters. The 100% protected neutral pole, line/load terminals, and included rear connectors (INCLUDE 6 REAR CONNECTORS) simplify wiring, enhance protection reliability, and support straightforward field installation, even in cramped or retrofit applications. Eaton’s one-year warranty (or 18 months from shipment) adds procurement certainty and aligns with standard industry practices for MCCBs in solar deployments.
