Littelfuse' SPXV and SPXN photovoltaic fuses protect solar installations
Littelfuse's SPXV and SPXN Series 1500 VDC photovoltaic fuses are designed to protect the next generation of solar installations. The fuses meet the requirements of 30kA interrupt ratings, 1500 VDC protection and global standards critical to solar equipment manufacturers.
The SPXV series includes string protection fuses from 6 to 20 amps in a 10 x 85 mm design and slightly wider 25 and 30 amp fuses, designed to fit the same holders. The standardized size allows for maximum flexibility of array construction, as fuse rating is often a final step in specification. With eight products under 30 amps, Littelfuse offers the broadest selection of fuse options. All of the new string protection fuses fit into a 1500V LPXV holder.
The higher amperage SPXN, with six models ranging from 200 amps to 400 amps, also comply with global standards, including UL2579 and IEC 60269-6. These products feature a ventilation-enhancing, cylindrical design, with sturdy melamine construction that meets the standard NH3L package size. The blade and bolt mounting feature provides flexibility in mounting and easy installation and replacement.
