Mersen’s HP6M photovoltaic (PV) fuse series is designed specifically
for the protection of PV string wiring for 600VDC residential and
commercial rooftop photovoltaic systems. Its enhanced construction
makes it ideal for continuous temperature and current cycling
withstand adding to system longevity. The 600VDC rated HP6M,
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 rooftop PV system from unexpected ground faults and string
faults using Mersen’s HelioProtection® fuse line.
APPLICATIONS:
• All photovoltaic applications
• PV string/array level protection
• Combiner box applications
• In-line PV module protection
• Inverters
• Battery charge controllers
