SPFI 1000VDC In-Line Solar Fuses

Littelfuse SPFI 1000V_DC In-Line Solar Fuses are 3.5A devices designed for integration into solar cables to protect solar strings connecting combiner boxes and panels. The SPFI is listed to UL2579 and meets the electrical performance requirements of IEC 60269-6. Littelfuse SPFI Solar Fuses are less than 44mm in length and 10.3mm in diameter and can be electrically insulated by either over-molding or using approved heat-shrink into the electrical cable for 1000V_DC solar installations.
