Mersen (formerly Ferraz Shawmut) is pleased to announce the launch of the newest and most efficient UL 2579 listed photovoltaic fuse – the HP10J, an exciting addition to the existing HelioProtection® fuse line, which already includes the HP6M, HP10M, and HP6J.

The new HP10J photovoltaic fuse line provides superior overcurrent protection at the re-combiner box and inverter levels and covers applications ranging from 70A to 400A, 1000VDC. The enhanced fuse construction of the HelioProtection series makes it ideal for continuous temperature and current cycling withstand adding to system longevity. Low minimum breaking capacity capabilities of 1.35 times the fuse-rated current value allows for safe circuit interruption under typical low-fault current conditions produced by PV arrays.

Protect off-grid or grid-tied PV systems from unexpected ground faults and line faults using the HelioProtection fuse line. Primary customers for this fuse are solar array combiner box builders, solar inverter manufacturers, and solar installers and integrators.

The conversion of solar energy to electricity is a reliable process, as long as it’s properly protected. In addition to its new Class J photovoltaic fuse offering for 1000VDC, Mersen offers a dedicated range of protection components specifically designed for solar power generation and distribution including, fuses, fuseholders, wire management solutions, disconnect switches, surge protective devices, monitoring solutions, and safety products.
