Model NO.: RW10-10/100 Type: Current Fuse Shape: Tablet Fusing Device: Pop-up Solid Rated Voltage: 12kv Rated Current of Melter: 3-100 a Weight: 7kg Transport Package: Wooden Cases Origin: Ningbo China Breaking Capacity: High Usaga: High Voltage Fusing Speed: FF Standard: UL Rated Current of Bottom Base: 100A Rated Short-Circuit Breaking Current: 6.3 Ka Trademark: VILLE Specification: IEC HS Code: 8535210000 General:
PRW11-12/3~100 fuse is used for short circuit protection of power transformer of power distribution and transmission in a power system with rated voltage 10kV, rated current less than 100A and frequency 50Hz.

Structure:
This kind of fuse consists of two parts: Fuse base and an arc-extinguishing device. Active and static contactor is of bridge structure. While fuse is in closing position, active and static contactors will be tightly pressed by compressed spring to guarantee a suitable pressure between contactors. A rotary torsion spring is equipped in the lower end of arc-extinguishing tube. When a fuse-element is put in the tube, the torsion spring will be screwed tightly, the fuse will be in drawing tightly condition to ensure the arc-extinguishing tube self-locked in closing position. When overload or short-circuit occurs, fuse-element will be melted and fuse will be quickly drawn out from the fuse tube by the torsion spring. Meanwhile, a great deal of arc-extinguishing gas is produced in the fuse tube by electric arc heat energy to extinguish electric arc quickly. After electric arc-extinguishing, the voltage between the both ends of the fuse is regained. The fuse tube will be dropped out by its weight and a function of compressed spring with bridge contactors. So an obvious disconnected section will be produced. Arc-extinguishing tube is designed at a step by step gas-discharging type.
