What is a fuse holder?lighting fuse block

　　　　Fuse holder refers to the holder used for installing fuses, which can be divided into panel mounted fuse holders, PCB mounted fuse holders, lead type fuse holders, and automotive fuse holders; Panel mounted fuse holder (mostly used for electrical equipment, such as power amplifier, DVD, speaker, Massage chair and other electrical equipment); Lead wire fuse holder (mostly used for connection of Small appliance and industrial machinery wire harness); PCB fuse holder (mostly used on the control board of Small appliance) and fuse clip (mostly used on the control board of Small appliance). Car fuse holders can be divided into lead type car fuse holders (commonly used in car and industrial machinery wiring harnesses); Panel mounted automotive fuse holders (commonly used in automotive appliances such as power amplifiers, refrigerators, DVDs, etc.) and automotive fuse clips. Fuse holders have requirements for current resistance, voltage resistance, and fire resistance, and generally requir

ge window air conditioner fuse location.What should I do if a fuse burns at home?

　　　　Summer residents are prone to frequent malfunctions in their homes, with blown fuses being one of them. If citizens find that the fuse in their home is burnt out, they should first investigate the cause, which mainly includes three types:　　1. Short circuit fault occurs in the electrical circuit (socket) at home;　　2. Overload electricity consumption;　　3. Quality issues with fuses.　　What to do if a fuse burns at home　　What to do if a fuse burns at home　　1. If there is a short circuit fault in the electrical circuit (socket) at home, it is necessary to first eliminate the fault, and then replace it with a new fuse (fuse) or replace it with an air switch of corresponding capacity;　　2. If it is overloaded with electricity, replace it with a new fuse or install an air switch of corresponding capacity to reduce the number of household appliances used simultaneously (especially high-power household appliances);　　3. If the above two fault causes are eliminated, namely the quality problem of

The Application of Self Recovery Fuses in RS485 Interface.volvo truck blower motor fuse location

　　　　As is well known, the interface of intelligent instruments was originally RS232, which can achieve point-to-point communication, but this method cannot achieve networking function. The subsequent RS485 resolved this issue. So the current RS485 interface is quite popular among intelligent instruments. Today, the editor will explain the application of self recovery fuses in the RS485 interface.　　RS485 has the advantages of long communication distance (over 1200m), high transmission rate (10Mbps), high signal-to-noise ratio, convenient control, low cost, and the ability to achieve multiple nodes on a single bus, as well as a variety of transceivers that can be used. It has been increasingly recognized by users.　　However, with the increase in usage frequency, the problems encountered by RS485 become more apparent. Due to its low voltage (only 5V), when using intelligent instruments with RS485 interfaces, the withstand voltage of the components themselves is also low, resulting in insta

Classification of fuses and fuses.fast acting fuse meaning

　　　　Spiral fuse: There is a fuse indicator on the upper cover of the melt. Once the melt melts, the indicator immediately pops up and can be observed through the glass hole on the ceramic cap. It is commonly used in machine tool electrical control equipment. Spiral type fuse. The breaking current is large and can be used for short circuit protection in circuits with voltage levels of 500V and below, and current levels of 200A and below.　　Enclosed fuses: Enclosed fuses are divided into two types: filled fuses and unfilled fuses, as shown in Figures 3 and 4. Fuses with fillers are generally made of square porcelain tubes filled with quartz sand and melt, with strong breaking capacity. They are used in circuits with voltage levels below 500V and current levels below 1KA. The unfilled sealed fuse packs the melt into a sealed cylinder, with a slightly smaller breaking capacity, and is used in power grids or distribution equipment below 500V and 600A.　　Quick fuse: Quick fuse is mainly used f

Detailed explanation of chip fuse performance classification.motorcycle fuse keeps blowing

　　　　Patch fuses can be divided into disposable patch fuses and patch self recovery fuses. After being protected by a disposable fuse, it needs to be replaced. After being protected by a self recovery fuse, it can be restored and reused after power failure.　　But what should we pay attention to when choosing patch fuses? The editor suggests selecting fuses based on the following aspects: normal current, fusing current, open circuit voltage, short circuit current, impulse current, and ambient temperature.　　Short circuit current: We refer to the maximum current that flows when a circuit is short circuited as the short circuit current. For various fuses, the rated breaking capacity is specified, and we must be careful not to exceed the rated breaking capacity when selecting fuses. If a fuse with a small breaking capacity is selected, it may cause the fuse to rupture or cause a fire.　　Impulse current: Observe the waveform of the impulse current (pulse current waveform) and calculate its ener
