Fuses: 19711250001 Application Field and Working Principle
Fuses are indispensable components in the modern electronic circuit, playing the role of overcurrent protection. This kind of fuse is mainly used for DC and AC circuits. This article is aimed at introducing the application field and working principle of 19711250001 fuses.
1. Application Field
19711250001 fuses can be applied to several fields: one is electrical systems and the other is electronic systems. In terms of electrical systems, this type of fuse can be used in the major power distribution systems and other wires and circulatory systems, including those with high and low voltage. In terms of electronics systems, 19711250001 fuses can be applied into home electronic products, such as electric cooker, sterilizer and some household appliances, as well as those products that require precise temperature control, like 3C products.
2. Working Principle
19711250001 fuse consists of three parts: fuse body, fuse wire, and arc quenching tube, as shown in Fig.1. And it has two working principles. The first one is that when overcurrent flows through the fuse, lots of heat is generated, and the fuse wire melts, so the circuit is broken. The second one is that, when overcurrent flows through the fuse, a large arc is generated and the arc quenching tube can absorb and break the arc effectively. In this way, the circuit is broken.
Both current and voltage of 19711250001 fuses can be specifically designed for particular application field. What’s more, the specific materials can be selected according to the work environment and product requirements.
As a conclusion, 19711250001 fuses are widely applied in electrical and electronic systems. The two working principles can be applied in different circuits to provide overcurrent protection and ensure a safe working environment.
