The “NH1XLgPV 1500V DC 63A-200A” is a type of high-performance photovoltaic (PV) fuse designed to protect solar power systems, especially in DC circuits operating up to 1500 volts. These fuses are commonly used in solar panel strings and DC combiner boxes to protect against overcurrent conditions. The NH1XLgPV fuse series combines robust construction with high breaking capacity, ensuring safe interruption of high fault currents in demanding solar applications.
