Mersen (formerly Ferraz Shawmut) has launched the industry’s first UL 2579 listed range of photovoltaic fuses ― the HelioProtection fuse line, which includes the HP6M, HP10M, and HP6J. The new line features 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. The enhanced fuse construction of the HelioProtection series makes it ideal for continuous temperature and current cycling withstand adding to system longevity, says Mersen.
