Overview

The Mersen HP15P10 is a 1500VDC photovoltaic (PV) fuse, specifically designed for string protection in demanding solar energy systems. Part of the HelioProtection® series, this 20x65mm fuse is engineered to handle higher amperage requirements and withstand harsh cyclical loads and thermal conditions inherent in PV installations. Its low minimum breaking capacity of 1.35 times its rated current ensures safe interruption under typical low fault conditions, safeguarding your PV arrays. The HP15P10 is certified to global standards, including UL Listed to Standard UL 248-19 and CSA Component Certified C22.2, with IEC 60269-6 compliance. It offers a Short-Circuit Current Rating (SCCR) of 50kA, providing robust protection against unexpected line faults. Available with standard ferrule or Crimp Cap terminals (indicated by the 'CC' suffix), the HP15P10 facilitates solderless, in-line fuse applications. This fuse is ideal for all photovoltaic applications, including PV string/array level protection, combiner box applications, in-line PV module protection, inverters, and battery charge controllers. Its durable construction enhances system longevity and guarantees operation at temperature extremes. Manufacturer: Mersen. SKU: HP15P10. UNSPSC: 39121606. Country of Origin: US.
