Mersen’s Photovoltaic (PV) fuse series was developed specifically for the protection of PV string wiring for 1000VDC industrial rooftop and utility scale photovoltaic systems. Its robust construction makes it ideal for continuous temperature and current cycling withstand adding to system longevity. The 1000VDC rated fuses, designed for low minimum breaking capacity capabilities of 1.35 times the fuse rated current value, when used with Mersen Fuse Holders allows for safe circuit interruption under typical low fault current conditions produced by PV arrays. In addition to the standard ferrule terminal, parts are available with Crimp Cap terminals for in-line fuse applications. The unique wire crimp terminal (CC option) permits solderless wire-to-fuse connection for overall encapsulation of fuse and wiring. Mersen HelioProtection® PV products (fuse base, fuse blocks, fuse holders, etc.) have been tested and certified to the latest industry standards for use in photovoltaic applications and guarantee the level of performance required by the PV industry.
