　　① Single direct starting motor melt rated current=(1.5-2.5) × Rated current of the motor.

　　② Total protection melt rated current of multiple direct starting motors=(1.5-2.5) × The sum of the currents of each motor.

　　③ Reduced voltage starting motor melt rated current=(1.5-2) × Rated current of the motor.

　　④ Rated current of winding motor melt=(1.2-1.5) × Rated current of the motor.

　　⑶ Rated current of low-voltage side melt of distribution transformer=(1.0~1.5) × Rated current on the low-voltage side of the transformer.

　　(4) Rated current of parallel capacitor bank melt=(1.43-1.55) × Rated current of capacitor bank.

　　(5) Rated current of welding machine melt=(1.5-2.5) × Load current.

　　Rated current of electronic rectifier element melt ≥ 1.57 × Rated current of rectifier components.

　　Explanation: The numerical range of the rated current of the melt is to adapt to the standard component rating of the melt.

Selection of 0.5A chip fuse.car fuses near me

　　　　The series models with a rated current of 0.5A in SMD fuses include ASMD0603-050, ASMD0805-050, ASMD1206-050, ASMD1210-050, ASMD1812-050, and ASMD2920-050. When selecting 0.5A patch recoverable insurance, in addition to considering the current, we also need to consider the voltage in the circuit. The maximum voltages for the above models in order are: 6V, 6V, 13.2V, 15V, and 60V. In addition to considering the voltage and current parameters, we also need to consider the requirements of the board for the fuse packaging size. The size of the 0603 is 1.6mm * 0.8mm, the size of the 0805 is 2.0mm * 1.2mm, the size of the 1206 is 3.2mm * 1.6mm, the size of the 1210 is 3.2mm * 2.5mm, and the size of the 2920 is 7.5mm * 5.5mm.　　0.5A circuit patch fuse selection, with a protective current of 1A, can restore the operating temperature range of the fuse to -40 ℃~+85 ℃ for patches above 0.5A. Usually, we use reflow soldering, which is mainly used for surface mounted boards, that is, for chip fu

What are the types of fuse boxes.automotive blade fuse dimensions

　　　　A fuse box refers to a box (also known as a fuse holder) that allows for dry installation of fuses. Some also have functional features such as waterproofing, fire resistance, and high temperature resistance (depending on different raw materials and shapes). The general injection molding materials for fuse boxes include plastic, nylon, bakelite, and PBT engineering plastics. Different raw materials have varying degrees of high temperature resistance. When selecting a fuse box, consideration should be given to the current and size requirements of the fuse used. The higher the fuse current, the larger the wires should be used to match the fuse box, otherwise it may cause the fuse box and wires to heat up and cause a fire.　　Fuse boxes can be divided into lead fuse boxes and automotive fuse boxes.　　The classification of fuse boxes can be divided into fuse boxes and fuse boxes based on the classification of device fuses.　　According to fuse subdivision, it can be divided into large fuse b

The difference between fuse and circuit breaker.battery fuse blown symptoms

　　　　The same thing is that both can achieve short-circuit protection. The principle of a fuse is to use current to flow through the conductor, causing it to heat up. After reaching the melting point of the conductor, the conductor melts, so disconnecting the circuit protects the electrical appliances and circuits from being burned out. It is an accumulation of heat, so overload protection can also be achieved. Once the melt burns out, it needs to be replaced.　　A circuit breaker can also achieve short-circuit and overload protection for circuits, but the principle is different. It achieves circuit breaker protection through the bottom magnetic effect of the current (electromagnetic release), and overload protection through the thermal effect of the current (not fusing, and there is often no need to replace components). In practice, when the electrical load in the circuit approaches the load of the fuse used for a long time, the fuse will gradually heat up until it blows. As mentioned ab
