Key features & benefits

Mersen’s HP15G photovoltaic (PV) fuse series was engineered
specifically for PV module ground fault protection of photovoltaic
systems. Its enhanced construction makes it ideal for continuous
temperature and current cycling withstand adding to system
longevity. The 1500VDC rated HP15G, designed for low minimum
breaking capacity capabilities of 1.35 times the fuse rated current
value, allows for safe circuit interruption under typical low ground
fault current conditions produced by PV arrays. In addition to the
standard ferrule terminal, these products 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 overmold
encapsulation of fuse and wiring. Protect your off-grid or grid tied PV
system from unexpected ground faults and string faults using Mersen’s
HelioProtection® fuse line.
