air conditioner fuse block pull-out.What is the breaking capacity of a fuse

　　　　As a safety component, in addition to its performance requirements, a fuse must also have strict safety requirements. The breaking capacity of a fuse is an important indicator reflecting the safety performance of the fuse. Its specific meaning is: the maximum short-circuit current that the fuse can withstand without any unsafe phenomena during the process of breaking the circuit. The unsafe phenomena here include - continuous arcing, smoking, spraying, splashing Burning, explosion, etc. Tubular fuses can be classified into high breaking (1500A), low breaking (35A or 10In), and enhanced breaking (150A) types based on their breaking capacity. The breaking capacity of chip fuses is generally between 30-60A, which is often overlooked or misunderstood by users or confused with the fusing characteristics of fuses, The correct understanding of the breaking capacity of a fuse should be that the extreme maximum current in the event of a short circuit in the protected circuit cannot exceed t

Fuses

　　　　Fuse, alias current fuse, is defined as "fuse link" in IEC127 standard and is a thermal Response element. The fuse is installed in a fuse box (fuse) or knife switch and connected in series in the circuit. The fuse invented by Edison over a hundred years ago was used to protect expensive incandescent lamps at that time.　　The fuse is mainly composed of three parts: the melt part, the electrode part, and the bracket part. Fuses are generally made of fusible metals such as lead, tin, lead-tin alloy, or zinc, with a very low melting point (approximately 200-300 ℃). Under normal circumstances, fuses can maintain reliable operation of the power grid, but in the event of overload or short circuit conditions, fuses with lower melting points are heated to the melting temperature by current and continue to be heated, causing some fuses to melt and vaporize, thereby cutting off the protected circuit and ensuring the safety of electrical appliances and connecting wires. Fuses are composed of po

High voltage fuse.battery fuse terminal

　　　　Fuses are the simplest protective devices used to protect electrical equipment from overload and short-circuit currents; Choose different types of high-voltage fuses according to installation conditions and purposes, such as outdoor drop type and indoor type. For some special equipment high-voltage fuses, special series should be selected; The fuse we often refer to is a fuse type. Nowadays, the Energy crisis and environmental pollution problems are increasing day by day, and the haze weather in a large area of the country has sounded an alarm bell for people. In terms of environmental pollution, the impact of cars cannot be ignored. Developing efficient, energy-saving, and zero emission clean electric vehicles has become an inevitable trend in the development of the automotive industry both domestically and internationally. In order to improve the power performance and range of electric vehicles, the voltage of the power battery pack of electric vehicles is increasing, reaching se

automotive blade fuse dimensions.Characteristics of Chip Fuses

　　　　With the development of technology, there are more and more components in circuit design, so the requirements for electronic component packaging are becoming smaller and smaller. The 0603 SMD fuse emerged in this context.　　The 0603 chip fuse provides ultra fast action fusing characteristics in a smaller chip size. The rated current value of the device is up to 4.0A, and its breaking capacity is 35A at a rated voltage of 32V.　　The 0603 fuse adopts standard metric dimensions (91.55mmx85mmx45mm) and can provide secondary overcurrent protection for low-voltage power supplies in DC-DC converters, battery chargers, and portable consumer electronic devices. Through strictly controlled manufacturing processes and advanced thick film technology, fuses provide excellent long-term stable fusing characteristics for portable devices such as mobile phones, PDAs, digital cameras, cameras, and LCD flat panel displays.　　The halogen free and lead-free 0603 chip self recovery fuse supports lead-free

mini blade fuse tap design.What are the application areas of glass tube fuses

　　　　1. According to the protection form: overcurrent protection and overheating protection. The fuse used for overcurrent protection is commonly referred to as a fuse (also known as a current limiting fuse). Fuses used for overheating protection are generally referred to as "temperature fuses". Temperature fuses are also divided into low melting point alloy type, temperature sensing contact type, and memory alloy type, etc. Temperature fuses are used to protect against excessive temperature changes in heating appliances or Yi Ge heating appliances, and their working principle is different from "current limiting fuses" The melting of temperature fuse melts is independent of the operating current of the circuit.　　2. According to the scope of use: power fuse, machine tool fuse, electrical instrument fuse (electronic fuse), automotive fuse.　　3. According to the rated voltage level: high-voltage fuse, low positive fuse, and safety voltage fuse.　　4. According to breaking capacity: high break
