Bourns’ PF-PVC150R Series POWrFuse High-Power Fuses are specifically designed to meet the evolving demands of next-generation photovoltaic (gPV) systems, including enhanced voltage and current ratings that comply with the UL 248-19 standard. The series’ higher voltage rating covers the higher operating ranges anticipated for future industrial/grid-scale systems, while its expanded current range supports broader application needs as well as helping extend R&D flexibility.

The PF-PVC150R series features 1,500-V DC and 4- to 30-A ratings, plus up to a 50-kA interrupting rating (IR) to help support improved power density and space utilization. The fuses, which are compatible with larger PV modules and string lengths, offer several package options with both ferrule and crimp cap configurations.
