Engineered to protect photovoltaic applications
Mersen’s HP10M photovoltaic (PV) fuse series was engineered and designed
specifically for the protection of photovoltaic systems. Its enhanced fuse construction
makes it ideal for continuous temperature and current cycling withstand adding to
system longevity. The 1000VDC rated HP10M, designed for 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. Protect
your off-grid or grid tied PV system from unexpected ground faults and line faults
using Mersen’s Helio Protection fuse line.
