Rsm0 Series Square Semiconductor Protection Fuse

one. Application
This collection fuse is appropriate for AC 50Hz, rated voltage to 1000V, rated present to 1250A. It is mainly utilized for guarding the electrical circuit against overload and quick-circuits(gG/gL). Due to the fact of various melting tablets, it also might derive for guarding the semiconductor device and other folks complete established installment from limited-circuit (aR/gR/gs) as properly as the electric powered motor from brief circuit (aM). The rated breaking capability is to 120KA. They conform to countrywide common GB13539 and global electrical committee common IEC60269.

two.CZPT Attribute
This sequence of fuse is composed of fuse link, fuse base and carrier fuse. The variable cross-segment fuse body manufactured by pure copper piece (or copper wire, silver wire, silver piece) is sealed in the square fusion tube which is made by the large strength porcelain or epoxy glass fabric pipe, there is full of the higher-purity quartz sand processed following chemistry to take the extinguishing of arc medium in the tube. The two sides of the fuse use the spot welding to reliably hook up with the end plate(or junction panel) and to kind the sq. knife condition contact composition. The fuse may have fuse indicator or striker, when the fuse aspect fusing it can demonstrate fusing (indicator) or transforms every single type of sign as well as automatic transfer circuit (striker). The fuse foundation is made up of higher temperature resistance resin plate(or substantial intensity porcelain plate) and wedge-shaped static speak to to type open-type structure and it can be utilized as the supporting system of the appropriate dimensions of the fuse hyperlink. This sequence of fuse has a lot of merits these kinds of as very good in heat dissipation, substantial mechanical toughness, trustworthy in contact, practical in efficiency and so on.
