Description

IEC 60269-4 RoHS compliance Mersen NH fuse-links 800VAC was engineered and designed specifically for photovotaic systems. gS 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. Applications • Inverter DC input protection • Re-combiner applications (sub combiner, array combiner, master combiner)
