Solar Fuse 25A

The Solar Fuse 25A is a specific model within Mersen's HP10M photovoltaic (PV) fuse series, which is designed to protect PV string wiring for 1000VDC industrial rooftop and utility scale photovoltaic systems.

The HP10M series is constructed with robust materials and engineered for continuous temperature and current cycling, ensuring a longer system lifespan. It is rated for 1000VDC and is designed with a low minimum breaking capacity of 1.35 times the fuse rated current value, allowing for safe circuit interruption under typical low fault current conditions produced by PV arrays.

In addition to the standard ferrule terminal, the HP10M series offers parts with Crimp Cap terminals for in-line fuse applications. The unique wire crimp terminal (CC option) enables a solderless wire-to-fuse connection for overmold encapsulation of fuse and wiring.

Overall, the HP10M series provides an essential protection mechanism for both off-grid and grid-tied PV systems, safeguarding against unexpected string faults.
