NH000 gG 80A / 500V safety link 004181213/004111437

The body of the fuse-link is made of full-fledged soapstone, which is very resistant to thermal loads.The covers made of aluminum are durable and corrosion-resistant.In the inner part of the ceramic body there is a copper fuse element, which is attached to a specially prepared inner part of the knife contact.Moreover, the inside of the ceramic body is filled with quartz sand with carefully selected granulation.Depending on the characteristics of the inserts, the knife contacts are made of both copper and brass, and protected with a layer of silver.The novelties include fuse links with a double indicator of operation - in the front front part of the body and on the top cover of the fuse link.Inserts with insulated hooks for inserting and removing inserts from the base and inserts with a striker are also available.Industrial knife fuses are designed to protect power installations against short-circuits and overloads.Their electrical parameters and external dimensions comply with the requirements. and cheaper, without affecting their parameters and possible use ›high short-circuit breaking capacity for all fuse sizes and rated currents› silver-plated contact knives - low power losses ›high short-circuit current limiting ability› stability of current-time characteristics and full selectivity of operation ›selective cooperation with miniature circuit breakers
