The HP10M1-V from Mersen is a Photovoltaic Fuse that is designed specifically to safeguard the PV string wire for utility-scale and industrial rooftop solar systems. It has a voltage rating of 1000 V and a current rating of 1 A. This PV fuse has an interrupting rating of 50 kA and provides guaranteed performance at extreme temperatures. It permits safe circuit disruption due to its low minimum breaking capacity capabilities under typical low fault current conditions produced by PV arrays. This RoHS-compliant fuse offers a robust structure for enhanced system longevity. It is available in a PCB mount package that measures 10 x 38 mm and is suitable for PV string/array level protection, combiner box applications, in-line PV module protection, battery charge controllers, and all photovoltaic applications.
