Fuses

Mersen HP15NH photovoltaic (PV) fuse serie was engineered and designed specifically for the protection of photovoltaic systems. Helio-Protection® HP15NH 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 1XL/2XL/3L sizes having a worldwide acceptance. They are of the gPV type and comply with both IEC 60269-6 and UL 2579 PV standards.
They are available with plain blades, bolted blades for direct mounting with and without striker.

Mersen NH gBat fuse series was engineered specifically for protection
of battery systems. They offer full range protection and can protect
very small over currents as well as DC fault current up to 150kA. The
NH gBat fuses serie covers various ratings in 1000VDC with NH1 and
NH2 sizes, and in 1500VDC with NH1XL, NH2XL and NH3L sizes. They are gBat type that comply with new IEC 60269-7 standard for Battery protection. They are available with bolted type blades for
direct mounting, or with plain blades.

Mersen NH fuse-links 800VAC was engineered and designed
specifically for photovotaic systems. gR types are full range breaking
capacity fuse-links and are used to protect cables and equipment.
They can interrupt any fault current, from overloads up to their
breaking capacity, and so can be used alone as protection. They are
the perfect solution of protection when used with DC/800VAC Solar
inverters.
This fuse range is offered along with Mersen 800VAC
Fuse-switch-disconnectors, for a complete fuse-system protection.
