A range of 10x38mm fuse links specifically designed for protecting photovoltaic strings. These fuse links are capable of interrupting low overcurrents associated with faulted photovoltaic string arrays (reverse current, multi-array fault). DC Fuse mainly used in DC combiner box in solar PV systems. When PV panel or imverter caused overload or short circuit, it trip off immediately, to protect PV panels, DC fuse aslo used to protect other electrical parts in DC circuit, when overload or short circuit.
