HP10NH1 Photovoltaic (PV) Fuses

Mersen HP10NH1 photovoltaic (PV) fuse series was designed specifically for photovoltaic output circuit (or array) protection. HelioProtection® HP10NH1 series fuses protect conductors against potential short-circuits in groups of strings. Target equipment includes solar re-combiner boxes, array combiner boxes, sub-combiner boxes and inverter input circuits.

HP10NH1 fuses are rated up to 1000VDC from 53 to 160A, furnished in a standard NH1 size fuse body. Photovoltaic fuse certifications include pending UL Listing to standard 2579 (due December 2012) and IEC Compliance to standard 60269-6. As an immediate advantage the HP10NH1 can be installed in two standard-length and 1000VDC qualified fuseholders: one is an open fuse-base and one is a base protected against electrical shock.
