Fuse is a common insurance device in our life, it can prevent the circuit due to its own load is too high to cause a short circuit and produce safety hazards. Ceramic tube fuse is a kind of fuse device that uses ceramic tube as the fuse housing, which is a very common kind of fuse device. There are many types of ceramic tube fuses on the market today.
Ceramic Tube Fuse Classification
If divided according to the scope of use, the ceramic tube fuse can be divided into power fuses, machine tool fuses, electrical instrumentation fuses and automotive fuses four categories, and if divided according to the size, can be divided into micro, small, medium and large fuses; If divided according to the breaking capacity, can be divided into high and low breaking capacity fuse, if divided according to the melting speed, it can be divided into special slow, slow, medium speed, medium fast, fast and special fast fuse. The three main brands of ceramic tube fuses are Sheng Ming, Lite and Warde.
Ceramic Tube Fuse Selection
In order to make sure that the fuse works smoothly and protects the safety of the circuit, we often need to determine a number of parameters of the fuse for selection. First of all, the first point to determine the safety mark of the fuse, according to the requirements of the market sales of the selected fuse tube safety certification standards. The second point is to determine the external dimensions of the fuse, mainly based on the installation space and determine the safety certification mark, the shape and size of the selected fuse. Third, to determine the type of fuse, according to the current characteristics of the protection circuit itself, selected the most suitable for the circuit model, for example, if the protection circuit current is a constant current, it should be selected fast blowing type fuse.
Fourth, to determine the rated voltage, and then combined with the input voltage of the protection circuit and the use of the requirements to select the most appropriate circuit of the fuse product. If the input voltage of the protection circuit is 220V, the voltage value should be selected above 220V fuse products; Fifth, to determine the minimum rated current, if the protection circuit of the stable too working current size of 1A, should be selected UL standard time-delay fuse tube; Sixth, to determine the minimum l2T fuse tube, if the protection circuit of the surge l2T 1, in order to ensure that the fuse can withstand more than 100,000 times the impact, then the fuse can withstand more than 100,000 times the impact, then the fuse tube is the most suitable for the circuit. If the protection circuit surge l2T is 1, in order to ensure that the fuse can withstand more than 100,000 times of impact, then the fuse l2T should be about 0.5. Seventh, to determine the size of the fuse tube rated current, according to the minimum rated current and the minimum l2T value, query the catalog of the corresponding specifications, take both greater than the minimum rated current and the value of l2T is greater than the minimum l2T value of the primary current rating for the fuse current rating.
