　　Basic knowledge and common fuse specifications of fuse wire base fuses

　　In many electronic devices, fuses are indispensable. Since Edison invented the

　　After the first plug-in fuse with a thin wire enclosed in the lamp holder, there are more and more types of fuses and their applications are becoming more and more widespread. Here are some common knowledge on fuse parameters, selection, and application.

　　The rated values and performance indicators of fuses are determined based on laboratory conditions and acceptance specifications. There are multiple authoritative testing and appraisal institutions internationally, such as UL certification from Underwriters Laboratories in the United States, CSA certification from the Canadian Standards Association, MTTI certification from the Japan Department of International Trade and Industry, and ICE certification from the International Electrotechnical Commission. The selection of fuses involves the following factors: 1. Normal operating current.home energy storage system battery

　　2. The applied voltage applied to the fuse.

　　3. Abnormal current that requires the fuse to be disconnected.

　　4. Short and long periods of abnormal current are allowed.

　　5. The ambient temperature of the fuse.

　　6. Pulse, impulse current, surge current, starting current, and circuit transient values.

　　7. Are there any special requirements that exceed the fuse specifications.

　　8. Dimensional limitations for installation structures.

　　9. Required certification body.

　　10. Fuse holder components: fuse clip, installation box, panel installation, etc. Below are some explanations of common parameters and terminology in fuse selection.
