The type of fuse is mainly selected according to the load and the circuit breaking current. You need to consider many factors.
Temperature has a direct impact on the performance of the fuse. In addition, there are many factors that will affect the temperature change on the fuse melt, such as the internal resistance of the fuse, the connection of the fuse, the surrounding heat dissipation conditions, altitude, etc.
In addition, improper selection of fuse technical parameters such as fuse characteristics, rated current, rated voltage and breaking capacity will certainly affect the normal functioning of the fuse.
When we select fuse, the most basic parameter information we need to provide is as follows:
1. Rated voltage of fuse: the fuse can only work at its specified voltage, so the fuse with rated voltage can only be used at rated voltage or lower. The working voltage of fuse shall not be higher than its rated voltage.
2. Rated current of fuse: It is necessary to know the continuous energizing current in the circuit, and the fuse should be able to carry the current indefinitely. In addition, you also need to know whether there will be current fluctuations or surges when the device is started. A good example is starting the motor. When starting, the motor will generate an initial current surge, and then the current will gradually stabilize. Before selecting a fuse, it is important to understand the objects to be protected by the fuse.
3. Certification certificate: If you want to export equipment or work in different markets, the fuse should comply with local standards.
In short, different applications need different solutions.If you don't know much about the fuse you need, you can consult the engineer team of Dissmann fuse for more technical support.
