30A 250V glass fuse with pin.glass fuse size chart

　　The safety tube is divided into glass safety tube and ceramic safety tube. The glass safety tube body is made of glass material, and the ceramic fuse tube body is made of ceramic material. Whether it is a glass safety tube or a ceramic safety tube, both ends of the material are made of nickel plated brass, and the pins of both types of safety tubes are also made of nickel plated brass material. The fuses inside the fuse are mainly made of alloy. Glass safety tubes are also divided into glass safety tubes with pins and glass safety tubes without pins. According to the speed of melting, there are three specifications: fast break glass safety tubes and slow break glass safety tubes: 3.6 * 10mm, 5 * 20mm, and 6 * 30mm. Next, let's learn about the detailed specifications and models of 30A 250V glass safety tube with pins.

　　There are 5 * 20mm specification JFG5F2300 glass fuse models that can achieve 30A and 250V. This part number can be divided into two types: with pins and without pins. The corresponding model for 30A and 250V glass fuse with pins is JFG5F2300L, where JF represents JDT FUSE brand fuse, G represents Glass glass, 5 represents 5 * 20mm specification fuse, 2300 represents current 30A fuse, and L represents Axoal Lead pin. JFG5F2300L glass fuse has a rated current of 30A, a rated voltage of 250V/125V, and a segmented capacity of 200A @ 250V AC (4A~10A). When the circuit current is 30A, the glass fuse should be maintained for at least 4 hours without melting; When the circuit current is 4050A, the fuse will fuse within 1 hour; When the circuit current is 600A, the fuse will fuse within 5 seconds. The working temperature range of JFG5F2300 glass safety tube is -55 ℃~+125 ℃. The safety tube can be stored for an average of 3 years under conditions of relative humidity ≤ 75%.

　　There are two installation methods for JFG5F2300 glass safety tubes, one is horizontal installation, and the other is vertical installation. The installation diagram is as follows:

　　There are two recommended welding methods, one is wave soldering, with a soldering temperature not exceeding 260 ℃ and a soldering dwell time of 2-5 seconds. Another welding method is manual welding, with a soldering iron temperature of 350 ± 5 ℃ and a heating time of no more than 5 seconds. The packaging method for glass safety tubes is usually bagged, with 250 pieces packed in a bag, 10 bags in a box, and 4 boxes in a box, so there are 1000 safety tubes in a cardboard box.
