Fuses are an important safety device used in the circuit, and BK/C519-7A is an important type of fuse. This type of fuse is widely used in the field of low-voltage power distribution. In this article, we will mainly analyze the application field and working principle of BK/C519-7A.

BK/C519-7A is a kind of meltable cutout fuse, which is also called solid-link fuse. Its rated voltage is 500V and its rated current is 10A. It is mainly used in the circuit of household electricity, as a protection device for fan and lights, and in the AC and DC circuits of appliances.

The hardware structures of BK/C519-7A are composed of two parts, which are body part and fuse-wire part. The body part contains two end caps, two supports, two conductive contacts and a encapsulating box. The fuse-wire part includes a pre-loaded fusible link and a fuse-wire holder. The fusible link is connected between the two conductive contacts and is mainly responsible for melting when the current is too large.

The working principle of BK/C519-7A is mainly relies on the pre-loaded fusible link and its melting action. When the normal current runs through the fuse-wire, the temperature will not be high enough to melt the fuse-wire. However, if the current is too large, the fuse-wire in the fuse will generate enough heat so that it will melt. When the fusible link in the fuse melts, the electric circuit will be cut off, the excessive current will be blocked, and the protection of the whole circuit will be achieved.

Although there are many types of fuses, BK/C519-7A still maintain its wide market share in low-voltage power distribution due to its excellent features, such as simple operation, safe and reliable performance, small volume and strong performance, as well as its renowned brand name.

In conclusion, BK/C519-7A fuse is an important safety device used in the circuit, which is widely used in the field of low-voltage power distribution. This type of fuse has a simple operation, safe and reliable performance, small volume, and strong performance. Its working principle mainly relies on the pre-loaded fusible link and its melting action.
