Sinofuse RS308-PV-3E Photovoltaic Fuse, 20A 1000V AC/DC, gPV Solar Protection, 10x38mm - Pack of 10

The Sinofuse RS308-PV-3E is a high-performance gPV (Photovoltaic) fuse specifically designed for the protection of solar energy systems. Engineered to handle the unique demands of DC strings, this fuse provides full-range protection against low overcurrents often associated with faulted PV string arrays. With a dual 1000V AC/DC rating, it is a versatile safety component essential for solar combiner boxes, inverters, and power distribution units.

Key Features

• gPV Application Class: Specifically designed to provide full-range breaking capacity for photovoltaic systems, addressing both short-circuit and low overcurrent faults.
• High Voltage Range: Rated at 1000V for both AC and DC operation, ensuring compatibility with high-voltage utility-scale and commercial solar installations.
• Precision Protection: Features a 20A rating with tight tolerance to prevent nuisance tripping while ensuring rapid isolation of faulted circuits.
• Compact Standard Size: The 10x38mm cylindrical format allows for easy integration into standard fuse holders and rail-mounted terminal blocks.
• High Breaking Capacity: Built to safely interrupt high-energy faults common in large DC arrays, preventing damage to downstream equipment and reducing fire risks.
