A good fuse has these three functions.bussmann radial fuse

　　　　The first function of a good fuse is maintenance. In general, the additional current of a fuse must be greater than the normal operating current of the circuit and have a certain overload capacity, but the margin cannot be too large.　　The second function of a good fuse is its load-bearing function. This is commonly referred to as the ability to withstand pulses. During the use of fuses, there is a greater chance of normal current fluctuations or instantaneous pulses than fault overcurrent, which is particularly important for the use of fuses.　　The third function of a good fuse is its safety function. A high-quality and reliable fuse should ensure safety before, during, and after its operation, that is, safely conducting and safely fusing. In summary, appropriate fusing characteristics and additional current; Satisfactory and reasonable melting heat energy value; Proper breaking ability, additional voltage, and safety certification are necessary conditions to ensure the main functio

Detailed explanation of JDT/JFP-F series quick break resistor type fuses.fast blow fuse vs circuit breaker

　　　　The characteristics of the JFP-F series quick break resistor type fuse include:　　1. Pin tensile strength: 5N for 10 ± 1 S;　　2. Pin thrust strength: 2N for 10 ± 1 S;　　3. Solderability:　　Wave soldering: 260 ℃, ≤ 3s;　　Soldering iron: 350 ± 10 ℃, ≤ 3s;　　4. Welding heat resistance:　　Wave soldering: 260 ℃, 10s;　　Soldering iron: 350 ℃, 5s　　The electrical characteristics of the JFP-F series quick break resistor type fuse are: all testing environments have a temperature of 25 ± 5 ℃,　　Load capacity: When the fuse passes through 100% of the rated current, it should not blow within 4 hours.　　Breaking capacity: The fuse can withstand breaking capacity: up to 50 A under 125/250 V AC power supply.　　Apply 1.0 times the rated current when the temperature stabilizes (measure 4 times within 5 minutes, and the difference between each measurement and the average value should not exceed 2 ℃). The temperature rise of any part of the fuse shall not exceed 75 ℃, and the ambient temperature shall be 25 ± 5

plastic fuse box under stairs.Precautions for the application of self restoring fuses

　　　　Easy to install:　　The WH self resetting overcurrent protector has no polarity and can be connected in series to the circuit that needs protection. It is not only widely used, but also safe and reliable.　　Reuse:　　After cutting off the power and troubleshooting, it automatically returns to normal state without the need for manual replacement and can be reused.　　Improving quality:　　It can improve the quality of customer products, greatly reduce the natural damage rate of finished products, and greatly extend the service life of products.　　No reconnection:　　Under fault conditions, the faulty circuit will not be reconnected (other protective circuits, bimetallic plates, etc. will be repeatedly reconnected to expand the fault range).　　Add highlights:　　Due to the addition of high-tech elements, it can add new shining points to customer products, making vulnerable circuits no longer fragile.　　Reduce costs:　　Reduce the number of components, PCB area, and damage during operation compared to
