Glass Tube Fuse Time-Lag 5*20 125V 250V Rt2-20

Model NO.: RT2-20 Type: Current Fuse Shape: Circle Fusing Device: Pop-up Solid Breaking Capacity: Low Usaga: Low Voltage Fusing Speed: T Standard: VDE RT2-20 series(Glass tube)
RT2-20 (H), dimension Ф5×20±1, ceramic tube, high breaking, slow blow, lead fuse, direct welding.
Fuse, as a security element, in addition to its performance requirements, must have strict safety requirements, an important indicator of fuse safety performance is reflected in breaking capacity of a fuse, which means the maximum short-circuit current a fuse can withstand without any unsafe phenomenon in the process of breaking the circuit, the unsafe phenomena include sustained arcing, smoke, spray, splash, combustion and explosion etc. Quartz sand is a good material for insulation, cooling and arc extinguishing. As a product full of quartz sand, it has good stability and security.
