Mersen's UL 2570 Listed Range of Dedicated Photovoltaic Fuses

Jan. 31, 2011
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.
