Eaton JGPVS3175W PV Guard MCCB - UL Listed, 3P 175A

Three-pole design delivers robust DC protection for PV arrays, reducing arc fault risk and improving system uptime in PV strings. This configuration directly translates to improved reliability and lower maintenance intervals for mid-size solar installations, where accurate protection at the source is critical. The device is PV-rated with a 600 Vdc rating and 1.2 kAIC interrupt capacity, enabling fast fault clearing and minimized damage to equipment downstream. In practice, that means fewer outages and safer shutdowns during fault conditions in DC distribution networks. The JG frame, described as a complete breaker with fixed thermal and fixed magnetic trip, ensures predictable tripping behavior and easy integration with standard Eaton accessories. Coupled with 80% rated operation, this breaker aligns with typical PV current profiles, optimizing conductor and wiring sizing while preserving protective margins. Terminals are not included with frames, which allows installers to select compatible terminal kits tailored to their busbar and cable sizing, improving install time and reducing unnecessary stock. UL Listed certification reinforces compliance with national electrical codes and utility interconnection requirements, while the photovoltaic class designation confirms suitability for PV system protection. In real-world terms, this means faster project handovers, reduced warranty questions, and a clear path to maintaining safe, code-compliant solar infrastructure.
