FAQ
AC fuses are not designed to interrupt continuous DC arcs. This PV fuse is specifically engineered for high-voltage DC applications, ensuring safe disconnection under fault conditions.
It means the fuse can safely interrupt short-circuit currents up to 33,000 amperes, providing high-level protection for solar installations.
The fuse features a visual indicator window. When the indicator light is ON, the fusible core has blown and needs replacement.
