The Littelfuse SPF® solar fuse series offers 1000VDC protection for photovoltaic systems (PV), including but not limited to combiner boxes, inverters and battery charge controllers. Some specific advantages of this new fuse line are:
UL Recognized up tp 1000VDC
13 ampere ratings, allowing for flexible design options
As PV systems have grown in size, so have the corresponding voltage requirements. This increase in system voltage has typically been intended to minimize power loss associated with long conductor runs. As the government continues to focus on solar applications, begining with the federal stimulus package, these application requirements are only going to grow.
As a result, the SPF Solar Protection Fuse series has been specifically designed for photovoltaic (PV) systems. This family of midget fuses (10x38mm) can safely protect PV modules and their conductors from reverse overcurrent conditions despite the associated challenges of DC power.
