Eaton LGEDC3500FAG PV Guard Solar MCCB - UL 489
Part Number: LGEDC3500FAG
Quick Summary
Eaton LGEDC3500FAG PV Guard Solar MCCB provides reliable overcurrent protection for DC solar PV systems. However, selecting a DC-rated breaker for PV installations can be challenging due to unique arc behavior and the need for precise trip characteristics. This product carries UL 489 certification, validating safety and performance for molded case breakers used in PV protection, with design tuned for LG-frame configurations in commercial and utility-scale installs. While CE or IP rating details aren’t listed in the current data, it integrates with standard line-load terminals and metric mounting for straightforward installation. The combination of compact form factor and robust interrupt ratings supports lower wiring costs, faster commissions, and improved system uptime.
