Eaton PVGard RGHDC3200FFWM - PV Solar MCCB 125 kAIC
Part Number: RGHDC3200FFWM
Quick Summary
PVGard PVGuard complete molded case circuit breaker protects solar PV systems with reliable DC and AC protection. Design and procurement teams often contend with nuisance tripping, rapid fault isolation, and mounting in outdoor or harsh environments. For this unit, validate CE marking and IP ratings in your region and check UL/CSA listings via Eaton datasheets to ensure compliance. The 2000 A rating, three-pole frame, and 125 kAIC interrupt capability at 240 Vac deliver robust protection while minimizing downtime. The solution also aligns with installation efficiencies, offering a fixed thermal/magnetic trip and rear-connector compatibility to speed field wiring and reduce total installed cost.

FAQs
Start by verifying the RG frame fits your enclosure and confirm rear connector availability as noted in the catalog. Mount the breaker with proper mechanical support, connect conductors per the without-terminals specification, and wire the PV DC side and AC side according to the system diagram. Ensure the trip unit is set to the correct protection level (T186) and perform functional tests after installation.
The device is a 3-pole complete molded case circuit breaker rated at 2000 A with a 125 kAIC interrupt rating at 240 Vac and 65 kAIC at 480 Vac. It is rated for 600 Vac and 250 Vdc, uses a fixed thermal/magnetic trip unit (T186), and is listed as RG frame with no terminals (rear connectors are included as catalog notes).
Yes. The breaker is designed for PV applications, offering DC ratings up to 250 Vdc and a high interrupt capability suitable for PV DC bus protection. Its fixed magnetic trip and robust rating help manage fault currents in PV arrays and protect downstream equipment.
Consult the PVGard product aids and technical data sheets from Eaton, including the PVGard solar circuit breakers product aid and the MCCB technical data sheet. These documents provide wiring diagrams, application notes, and compliance guidance for CE/UL/CSA listings where applicable.
PVGard assemblies offer high interrupt ratings, reliable fault isolation, and compatibility with rear connectors that simplify wiring. This reduces downtime, shortens commissioning times, and lowers total installed cost by consolidating protection needs into a single, robust MCCB suitable for diverse PV environments.
