Eaton RGHDC3200FFWE PVGuard Solar MCB - 125 kAIC at 240 Vac
Part Number: RGHDC3200FFWE
Quick Summary
PVGuard solar molded case circuit breaker protects PV arrays and electrical systems in utility-scale and commercial solar installations. Engineers often wrestle with DC protection, wide voltage ratings, and reliable trip performance under PV conditions. Certifications and compliance play a critical role in project acceptance; typical PV protection equipment relies on industry standards such as SIL, CE, and IP ratings to validate safety and reliability. This product aligns with high-current, DC/AC PV protection needs, while offering compatibility and installation advantages to support solar program timelines and total cost of ownership.

Feature → Business Impact → Application. High amperage rating and wide voltage coverage: with a 2000 A rating and voltage options of 600 Vac / 250 Vdc, this MCCB supports large PV inverters and bus bars, reducing the risk of nuisance trips during peak irradiance and enabling safer, scalable solar installations. Application: utility-scale PV integrators and commercial solar projects benefit from fewer protective devices in parallel and simplified protection schemes. DC/AC protection and fixed trip units: the fixed thermal and magnetic trip ensures rapid fault clearance with predictable coordination, delivering improved system reliability and easier UL/NEC compliance for PV systems. Application: string combiner boxes and PV arrays where stable DC protection is essential. Three-pole RG frame with line/load terminals: robust, field-friendly connections and a compact footprint enable faster installation, lower wiring errors, and straightforward retrofit into existing protection schemes. Application: greenfield and brownfield solar facilities seeking reliable protection architecture. 100% protected neutral pole: enhanced fault isolation and safer operation, particularly in multi-string PV configurations. Application: PV farms requiring strict neutral integrity for downstream inverters and protection devices. Includes rear connectors: catalog notes specify six rear connectors to streamline wiring during panel assembly and reduce field labor. Application: installers targeting faster, error-free commissioning. Warranty and support: standard Eaton warranty and policy support help protect long-term ROI and maintenance planning for solar projects.

FAQs
This three-pole RG frame breaker uses line and load terminals and, per catalog notes, includes six rear connectors to speed wiring. Verify the installer interface with existing Eaton MCCB panels and ensure proper neutral handling for a 100% protected neutral pole configuration.
Amperage rating is 2000 A, voltage ratings are 600 Vac and 250 Vdc, and interrupt ratings are 125 kAIC at 240 Vac and 65 kAIC at 480 Vac. Trip type is T186 with fixed thermal and magnetic trips, and the device is a three-pole RG frame MCCB.
Yes. It provides DC protection up to 250 Vdc and AC protection up to 600 Vac, designed for PV systems and solar inverters. The PVGard designation emphasizes protection tailored for PV environments, including reliable DC protection and coordinated AC protection.
The unit features line/load terminals and supports rear connectors (six included), which simplifies wiring, reduces field labor, and helps maintain proper protection scheme integrity in large PV arrays.
The product carries Eaton’s standard warranty terms (25-000), typically one year from installation or eighteen months from shipment, whichever occurs first, with manufacturer support available for compliance questions and replacement parts.
