| Datasheet | Download Datasheet |
The Littelfuse SPXI2.25T is a 2.25 A fast-acting photovoltaic (gPV) fuse, rated 1500 VDC.
A gPV fuse is rated for photovoltaic strings: DC voltage up to the array's open-circuit level and the low fault currents of solar panels. A fast-acting fuse opens quickly on an overload, for resistive and lightly loaded circuits with little switch-on surge.
Interrupting rating: 30 kA (50 kA self-certified). Pre-arcing I²t 5.00 A²s.
Construction: 10.31 x 81.41 mm diameter x length; in-line crimp barrel, 10-12 AWG (6-4 mm²).
It is UL Recognized, cUL and TÜV certified.
