Feature *20 10*38mm fuse fuses, 1~32A complete specifications *Widely used in high and low voltage power distribution systems and control systems and electrical equipment, as a pseudo-short circuit and overcurrent protector, is of the most commonly used and most important protections * High-quality ceramic shell, the principle of the fuse is to use the current to stream through the conductor to generate heat. After reaching the melting point of the conductor, the conductor melts, so the circuit is disconnected to protect the electrical appliances and lines from being burned out. *The copper core contacts the round cap, the contact area is large, and it is not easy to be oxidized, which greatly reduces the influence of accidental peak current on electrical appliances *The melt is encapsulated in a melting tube made of high-strength organic materials, and the melting tube is filled with chemically treated high-purity quartz sand as an arc extinguishing medium *Match RT18 fuse base Specification Product name: ceramic fuse Item model number: RO15 RT18 Product material: ceramic shell/copper cap Product current: 1~32A optional Product voltage: 500V~50KA Ambient temperature: -50℃~+40℃ Product packaging: 20 pcs/box Product size: 10*38mm Product size is purely manual measurement, there may be ±0.2mm error, please understand if there is any inconvenience Packing list: 20*Ceramic fuse Made of high quality material, durable and practical to use.
