Eaton RGHDC3160FFWE PV Guard MC CB - 1600A, 600 Vac, 3-Pole
Part Number: RGHDC3160FFWE
Quick Summary
The Eaton RGHDC3160FFWE PV Guard molded case circuit breaker protects PV power systems with fixed thermal and magnetic trips. Engineers often struggle with protection coordination, accurate amperage sizing, and reliable DC/AC interface protection in solar installations. These devices typically align with UL/CSA listings and CE marking, with IEC/DC performance standards supporting PV safety. For project teams, this translates to faster compliance, reduced wiring errors, and improved uptime across utility-scale or commercial PV deployments while delivering robust, long-term protection for PV arrays and inverters.

FAQs
Yes. The RGHDC3160FFWE uses the RG frame with line and load terminals and imperial mounting hardware, designed to drop into compatible RG-series panels. Catalog notes specify rear connectors, making retrofits straightforward and ensuring reliable mounting without custom adaptors.
It is rated for 1600 A, with voltage ratings of 600 Vac and 250 Vdc. The trip type is T186, and the device delivers 65 kAIC at 480 Vac and 125 kAIC at 240 Vac, suitable for high-current PV inverter protection and DC protection in solar installations.
Best suited for PV systems requiring robust three-pole protection with fixed thermal/magnetic trips, including PV arrays, DC bus protection, and PV inverter interfaces, especially where high fault current and long-term reliability are critical.
Compliances are listed as Contact Manufacturer in the data, but for PV applications you should anticipate UL/CSA listings and CE marking, along with IEC/EN standards applicable to molded case circuit breakers used in PV protection schemes.
The unit’s line/load terminals, imperial mounting hardware, and rear connector options simplify field wiring, reduce install time, and minimize training needs. High interrupt ratings plus DC/AC compatibility translate to lower downstream maintenance costs and fewer protection-related outages.
