　　1、 Choose Fuse Type

　　The first step in selecting a fuse is to determine the type and size required. Common structures and sizes include the following:

　　1. Tubular type: glass or ceramic tube body, with a general size of 3.6x10mm 5x15mm 5x20 6.3x32mm;

　　2. Plastic shell type: PA66 shell, small in size, woven with machine insertion, generally 8.5x8mm 8.5x7.6mm in size;

　　3. Epoxy resin type: ceramic tube body, surface sealing resin, micro type, woven machine insert, size: 3x7mm;

　　4. Surface mount: suitable for high-density circuit boards, with dimensions of 0402 0603 1206 6125 1032;

　　5. Automotive fuses: generally used in conjunction with terminals or boxes, specifically for use in automotive or low-voltage, high current systems;

The Role of Current Fuses in Smart Meters

　　　　Current fuses play a vital role in smart meters. Firstly, they provide protection against overcurrent events. Smart meters are used to measure and manage electricity consumption accurately. However, electrical circuits can sometimes experience sudden surges in current due to various reasons such as power outages and subsequent restoration, short circuits in the electrical grid, or the malfunction of connected electrical appliances. The current fuse in the smart meter acts as a safeguard by interrupting the circuit when the current exceeds a safe level. This prevents damage to the sensitive electronic components inside the smart meter, which are essential for accurate measurement and communication. Without the fuse, an overcurrent event could potentially damage the circuitry, leading to inaccurate readings or even complete failure of the smart meter. Secondly, current fuses in smart meters help to ensure the safety of the overall electrical system. In case of a fault in the downstre

Starting protection time of self recovery fuse.charger fuse in car

　　　　The starting time of protection has regularity, firstly, it is inversely proportional to the size of the components; Compared to the size of electronic devices, i.e. in the same series, such as the software fuse of the 250V series product, the smaller the current, the smaller the electronic device, which is twice the normal current. Due to its small size, fast heating, and faster startup protection time. Compared to the size of the fault current, it is easy to understand that the larger the fault current, the faster the component heats up and the faster the protection.　　When selecting a self recovery fuse, we all want to know whether the startup protection rate of the self recovery fuse is sufficient and immediate when a fault current occurs in the power circuit to protect the power circuit machine equipment.　　There are many models of self recovery fuses, and the starting protection rate varies among different models. And the time period required for starting protection under diffe

Experience in selecting self recovering fuses

　　　　Do you have any good experience to share in selecting self recovering fuses? Self recovery fuse is an overcurrent electronic protection component, which is made of high molecular weight organic polymers under high voltage, high temperature, and sulfurization reaction conditions, mixed with conductive particle materials, and processed through special processes.　　The main function of a self-healing fuse is to provide overcurrent protection in electrical appliances. Therefore, self recovering fuses have parameters such as withstand voltage, withstand current, maintain current, and action time. Therefore, it is necessary to choose a suitable self recovery fuse based on the voltage, current, and protection current of the product used.　　The selection method for self recovery fuses is as follows:　　Firstly, determine the maximum ambient temperature, operating current, maximum operating voltage, required protection current, and action time parameters for the protected circuit to operate nor

frigidaire window air conditioner fuse location.Precautions for using fuses and fuses

　　　　1. The fuse is connected in series with the circuit, installed vertically, and installed on each phase line; Fuses are not allowed to be installed on the neutral line of a two phase three wire or three-phase four wire circuit.　　2. The power input terminal of the spiral fuse should be connected to the center point of the base, and the output wire should be connected to the threaded shell; This insurance is used in places with vibrations.　　When the power load is greater than 60A and the lighting or electric heating load (220V) is greater than 100A, a tubular fuse should be used.　　4. The voltage circuit and electrical control circuit of the electricity meter should be equipped with control fuses.　　5. Porcelain plugs shall be made of qualified lead alloy wire or copper wire, and multiple strands of fuse wire shall not be used instead of a large fuse wire.　　6. The fuse should be intact and undamaged, and the contact should be tight and reliable. In conjunction with the maintenance of th
