SGF5‑50P is a high‑voltage DC fuse disconnector for modern photovoltaic and energy‑storage DC systems. It uses high‑melting‑point PA66 shell for enhanced safety. Matched with silver‑based fuse links, it protects PV circuits against overload and short‑circuit. Rated up to 1500V DC with 2‑50A current range, supports 20kA/25kA breaking capacity. Standard 35 mm DIN‑rail installation, widely used in large‑scale solar plants, high‑voltage combiner boxes and energy‑storage cabinets. Complies with IEC60269 standard.
Standard DIN‑rail mounting, IP20 protection degree.
