Design Features

Variable cross-section fuse element made from pure metal sealed in cartridge made from high-duty ceramic or epoxy glass.Fuse tube filled with chemically treated high-purity quartz sand as arc-extinguishing medium.Dot-welding of fuse element ends to the caps ensures raliable electric connection; Striker may be attached to the fuse link to provide immediate activation of micro-switch to give various signals or cut the circuit automatically. According to customer demands we can also produce speccial fuse body,this series of fuse-type plug-in structure, according to the size ,it can be installed in the RT14,RT18,RT19 and other corresponding size fuse assembly.
