gPV NH 800V AC fuse links

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. 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.
