SGF5-32P DC Fuse

Product Overview

SGF5‑32P is a DC fuse disconnector developed for solar photovoltaic and energy‑storage DC systems. The housing adopts high‑melting‑point PA66 material to ensure high safety and reliability. Equipped with pure silver fuse link, it provides over‑current and short‑circuit protection for PV string circuits. Rated up to 1000V DC, 2‑32A current range, fits standard 35 mm DIN‑rail mounting, widely used in photovoltaic combiner boxes and DC distribution cabinets. Complies with IEC60269‑1, IEC60269‑6 standards.

Key Characteristics

• High‑melting‑point PA66 shell, excellent thermal stability and safety.
• Pure‑silver fuse element inside high‑strength porcelain tube, filled with high‑purity quartz‑sand for good arc‑extinguishing performance.
• Rated voltage: 1000V DC, rated current: 2‑32A.
• Breaking capacity up to 20kA for reliable short‑circuit protection.
• Wiring cross‑section: 1‑10 mm².
• Wide operating temperature: ‑40℃ ~ +90℃, adapt to outdoor PV working conditions.
• Standard DIN‑rail installation, IP20 protection degree.
