Intended 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. 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.

RAPIDPLUS aR fuse links are intended to clearing short-circuits and have been designed and manufactured to have very low I²t values as well as reduced arc voltages that guarantee an optimum protection of semiconductors. They have a very good cycling ability.RAPIDPLUS aRrange comprise three sizes with dimensions 10×38, 14×51 and 22×58, with rated currents between 1A and 100A and a rated voltage of 690 V AC. Sizes 14×51 and 22×58 are available also with striker, for use in fuse bases with microswitch. Made of ceramic tubes with high withstand to internal pressure and thermal shock, and silver plated copper contacts.

RAPIDPLUS gR fuse linksare capable to clearing all types of overcurrents, overloads as well as short-circuits, thus the fuse links protect semiconductors as well as cables and all switchgear of installation.RAPIDPLUS gRrange comprise three sizes with dimensions 10×38, 14×51 and 22×58, with rated currents between 1A and 100A and a rated voltage of 690V AC. Sizes 14×51 and 22×58 are available also with striker, for use in fuse bases with microswitch.
