NH Fuse-Links, Fuse-Bases and Fuse-Disconnectors

Mersen’s ProGrid represents a new generation of protection devices aimed at optimizing the reliability and safety of distribution infrastructures, while facilitating predictive maintenance and energy efficiency.

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.
