New Helio Protection® Fuse Product Line

Introducing the Industry's First UL 2579 Listed Range of Dedicated Photovoltaic Fuses.

Mersen is pleased to announce the launch of the industry's first UL 2579 listed range of dedicated photovoltaic fuses - the Helio Protection fuse line, which includes the HP6M, HP10M, and HP6J.

The new photovoltaic fuse line provides superior overcurrent protection at the combiner box and inverter levels and covers applications ranging from 1 to 400A, 600VDC, and 1000VDC. The enhanced fuse construction of the Helio Protection 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 Helio Protection fuse line. Primary customers for this fuse are solar combiner and re-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 is properly protected. In addition to its new photovoltaic fuse line, Mersen offers a dedicated range of protection components specifically designed for solar power generation and distribution including fuses, fuse holders, wire management solutions, disconnect switches, and surge protective devices.
