single phase and multi-phase with LED and without LED
Application
This series fuse is suitable for AC 50Hz , rated voltage to 690V, rated current to 125A. It is mainly used for protecting the electrical circuit against overload and short-circuits(gG-gL); It also may derive for protecting the semiconductor device and others complete set installment from short-circuit(aR) as well as the electric motor from short-circuit(aM).
The rated breaking capability for this series fuse is to 100KA. This series fuse conforms to national standard GB13539 and international electrical committee standard IEC60269.
Construction feature
The variable cross-section for body made by pure copper/ silver piece (or silver wire) is sealed in the fusion tube which is made by the high strength porcelain or epoxy glass cloth pipe; these is full of the high purity quartz sand processed after chemistry to take the extinguishing of arc medium in the tube. The two sides of the fuse use the spot welding to reliably connect with the end plate. the fuse may have striker, when the fuse element fusing the striker will act immediately to push the micro swith and send out each kind of signal or automatically transfer the circuit. According to requirement of user, it also may produce special fuse body.
