Interrupting Rating ka - A - A ka - A - A Time Constant ms Material Body: Melamine Caps: Copper Alloy Approvals UL - Listed (File: E) IEC - (- A) CSA Certified (File: 0_0_000) Environmental RoHS Compliant Country of Origin Mexico Description The SPF Solar Protection Fuse series has been specifically designed for the protection of photovoltaic (PV) systems. This family of Midget style fuses (0 x mm) can safely protect PV modules and conductors from reverseovercurrent conditions. 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. Standard circuit protection devices are not designed to completely protect photovoltaic panels. However, the SPF series is UL Listed to safely interrupt faulted circuits up to this demanding voltage level. Littelfuse offers ampere ratings to match specific requirements in a variety of applications.
