This series fuse is mainly used for protecting the electrical circuit against overload and short-circuits(gG/gL). Because of different melting tablets, it also may derive for聽protecting the semiconductor device and others complete set installment from short-circuit (aR/gR/gs/gtr) as well as the electric motor from short-circuit (aM). They conform to national standard GB13539 and international electrical committee standard IEC60269.
This series of fuse consists of fuse link and fuse base. The fuse bases is made of high strength ceramic floor or high temperature resin floor, wedge-shaped combination of static contact. It is open structure and with good heat dissipation, high mechanical strength, access to reliable and easy to operate. Matched with this series, NH fuse puller is used to pull the fuse from the base.The fuse body made by pure copper or silver piece(or silver wire) is sealed in the fusion tube which is made by the high strength porcelain.
There is full聽of the high-purity quartz sand processed after chemistry to take the extinguishing聽of arc medium in the tube.The fuse may have fuse indicator or striker,when the fuse element fusing it can demonstrate fusing or transforms each聽kind of signal as well as automatic transfer circuit(striker).
