RS3 Fast Acting aR 200A Fuse
1. Application
This series fuse is suitable for AC 50Hz, rated voltage to 1000V, rated current to 2500A. It is mainly used in the electrical circuit for protecting the semiconductor device and it’s complete set installment from short-circuit(aR). The rated breaking capacity is to 100KA. They conform to national standard GB13539.1/ GB13539.4 and IEC60269-1/ IEC60269-4.
2.Construction Feature
The variable cross-section fuse body made by pure silver piece is sealed in the fusion tube which is made by the high strength porcelain or epoxy glass cloth pipe, there 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 contact. The fuse body may have fuse indicator or striker, when the fuse element fusing,the indicator or the striker can act immediately to display the fuse body has been blown out(indicator) or send out each kind of signal and automatically transfer the circuit(striker).
