MERSEN HP15M4R
MERSEN HP15M4R Photovoltaic Fuse – 4A, 1500 VDC
The Mersen HP15M4R is a GEN2 gPV photovoltaic fuse engineered to withstand the severe temperature variations and current cycling found in modern solar power systems. Rated for 1500 VDC, this fuse provides reliable protection under low fault current conditions, with a minimum breaking capacity of 1.35× the rated current. Featuring tin-plated copper ferrule terminals and compatibility with clip-style fuse holders, the HP15M4R is ideal for protecting both grid-tied and off-grid PV installations using Mersen’s HelioProtection® fuse technology.
