Product Description

Model NO.: RT1-20 (H) Type: Current Fuse Shape: Insert Fusing Device: Pop-up Solid Trademark: Songshan Origin: Shanghai, China Breaking Capacity: High Usaga: Low Voltage Fusing Speed: T Standard: TUV Specification: 5.0x20 mm HS Code: 85361000 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. The circuit the fuse protects has large working current, when the melt blows, 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 off, 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.
