Ceramic Tube Fuse 5*20 Time-Lag High-Breaking 125V/250V Rt1-20 (H)
Basic Info
Model No.: RT1-20 (H)
Product Description
Model NO.: RT1-20 (H) Type: Current Fuse Shape: Insert Fusing Device: Pop-up Solid Breaking Capacity: High Usaga: Low Voltage Fusing Speed: T Standard: VDE RT1-20 (H) series
RT1-20 (H) is ceramic tube, high breaking, delay fuse. The dimension is Ф5×20±0.5. The fuse is used in power circuit and large power equipment, not only has three parts of the general fuse, but also interrupter device, because the circuit the fuse protects has not only large working current, but also when the melt blows and the voltage of both ends is very high, there often appears a phenomenon that the melt has been melted, even up to vaporization, but the current is not cut, the reason is that in a flash under the action of voltage and current, the arc phenomenon occurs between the two electrodes of the fuse. The interrupter device must have strong insulation and good thermal conductivity, and be negatively charged. Quartz sand filled in this product is a commonly used arc extinguishing material.
