Feature → Business Impact → Application: The PV Guard RG frame delivers a 1600 A amperage rating and voltage robustness up to 600 Vac and 250 Vdc, enabling protection for large solar arrays and mixed AC/DC infrastructure with fewer components and simplified coordination. This translates to improved system availability and reduced downtime during fault events in utility-scale PV farms and commercial rooftops. Feature → Business Impact → Application: The fixed thermal/magnetic trip (T186) provides reliable and predictable fault response, improving safety, minimizing arc risks, and ensuring rapid isolation of faults in high-current environments, essential for grid-tied PV inverters and DC string protection. Feature → Business Impact → Application: High interrupt ratings—65 kAIC at 480 Vac and 125 kAIC at 240 Vac—support strong fault-current withstand in interconnection points, aiding compliance with utility requirements and minimizing damage. Feature → Business Impact → Application: RG frame, three-pole design with metric mounting and six rear connectors simplifies installation in existing enclosures, reduces field modification needs, and accelerates project timelines in new or retrofit PV installations. Feature → Business Impact → Application: Catalog notes specifying rear connectors and a no-terminal default layout reduce wiring errors and installation time, lowering total cost of ownership for maintenance teams and enhancing long-term reliability. Feature → Business Impact → Application: Durable, purpose-built for solar protection, the PV Guard MCCB integrates with Series G hardware and standard MCCB ecosystems, supporting scalable protection strategies across campuses, factories, and solar farms.

FAQs
The Eaton PV Guard RG-series MCCB is designed for solar PV protection in utility-scale, commercial, and industrial installations. Its 1600 A rating and 600 Vac/250 Vdc capabilities suit both AC distribution and DC protection needs, while its metric mounting and rear connectors simplify integration into standard enclosures and PV inverter rooms.
Key specs include 1600 A amperage rating, 600 Vac/250 Vdc voltage ratings, fixed thermal/magnetic trip (T186), and interrupt ratings of 65 kAIC at 480 Vac and 125 kAIC at 240 Vac. It is a three-pole RG frame device, designed for reliable protection in mixed AC/DC PV systems.
Yes. The device supports 480 Vac operations with 65 kAIC interruption, and it also protects 240 Vdc PV strings, offering 125 kAIC interruption at 240 Vac, making it suitable for common PV system interconnections and grid-tied configurations.
Compliance details are typically region-specific and may include CE, UL/CSA, and applicable PV protection standards. Always verify current certification status with Eaton or your local distributor to ensure alignment with regional electrical codes and project requirements.
The rugged RG frame with high interrupt ratings reduces the risk of overcurrent damage, lowering downtime and replacement costs. Its six rear connectors and metric mounting streamline installation and service, shortening commissioning time and improving overall system availability, which translates to a shorter payback period for PV projects.
