NH gG/gL & gS fuse links 800V AC
NH fuse links for output side of new generation of photovoltaic inverters
These knife type (NH) fuse links with high breaking capacity are intended for protection of the output side of new generation of photovoltaic inverters, with output voltage of 800V AC.
They are also adequate for the protection of 690V AC capacitor banks. They are gG class and provide protection against overloads and short-circuits with rated voltages up to 800V +10%. The rated breaking capacity is 80kA and 120kA(NH00 size). They have a low values of power dissipations. Manufactured with ceramic body with high withstand to internal pressuree and thermal shock, that allows a high breaking capacity. Knife contacts are made of silver plated copper or brass.
Can be mounted in open-type ST fuse bases or in fuse disconnectors type BS.
