Square Pipe Knife-Shape Contact Fuse

Square Pipe Knife-Shape Contact Fuse

one. Application
This collection fuse is suitable for AC 50Hz, rated voltage to 1000V, rated existing to 1250A. It is primarily utilized for protecting the electrical circuit towards overload and quick-circuits(gG/gL). Because of diverse melting tablets, it also could derive for safeguarding the semiconductor gadget and other folks complete set installment from short-circuit (aR/gR/gs) as properly as the electric powered motor from short circuit (aM). The rated breaking potential is to 120KA. They conform to countrywide common GB13539 and global electrical committee standard IEC60269.

two.CZPT Function
This sequence of fuse is composed of fuse hyperlink, fuse base and carrier fuse. The variable cross-part fuse physique produced by pure copper piece (or copper wire, silver wire, silver piece) is sealed in the square fusion tube which is made by the large energy porcelain or epoxy glass cloth pipe, there is complete of the high-purity quartz sand processed following chemistry to just take the extinguishing of arc medium in the tube. The two sides of the fuse use the location welding to reliably hook up with the stop plate(or junction panel) and to kind the square knife condition get in touch with framework. The fuse may have fuse indicator or striker, when the fuse element fusing it can show fusing (indicator) or transforms every variety of signal as nicely as computerized transfer circuit (striker). The fuse foundation is composed of large temperature resistance resin plate(or substantial intensity porcelain plate) and wedge-shaped static contact to form open-kind framework and it can be utilized as the supporting gadget of the acceptable measurement of the fuse url. This series of fuse has many merits this kind of as good in warmth dissipation, higher mechanical power, reputable in contact, convenient in performance and so on.
