Photovoltaic fuse-links gPV 1250VDC
Photovoltaic Fuses
Mersen HP12NH photovoltaic (PV) fuse series was engineered and designed
specifically for the protection of photovoltaic systems. Helio-Protection
®
HP12NH
fuse links are designed for the protection of cables in a PV group of chains when a
short circuit occurs in a panel (main fuse category). This HelioProtection
®
main fuse
range enlarges our PV fuse links offering on a size having a worldwide acceptance.
They are of the gPV type and comply with both IEC 60269-6 and UL 2579 PV
standards.
They are also available with bolted type blades for direct mounting.
