Fuses are the most common type of overcurrent protection device used in industrial and electrical applications. They are devices that contain a short length of fusible metal wire and a heat-resistant protective element, such as a ceramic tube or an oven-baked, heat-resistant enclosure. The fusible wire is typically composed of an alloy, such as tin or lead, and the heat-resistant protective element helps protect the wire from thermal damage.

Fuses are typically used to protect circuits and equipment from becoming damaged due to processes such as short circuits, overloads, or even malicious intent. Fuses work by providing a low resistance path to allow current to flow through when there is an excess current flow. When the current exceeds a specific predetermined amount, the fusible metal wire melts, thus disrupting the flow of current and protecting the circuit or equipment.

7100.1113.13 application field and working principle is one such type of device. This particular type of fuse is primarily used in applications such as industrial generators, high voltage switchgear, transformers, and motor starters. The device is composed of a fuse element made of copper or non-metallic material with an overcurrent shutoff circuit for protection. It features a high-temperature limiting time-delay circuit, thus allowing the device to not only protect against overcurrents, but also against inrush currents.

The working principle of a 7100.1113.13 application field and working principle fuse is relatively straightforward. When the current on the circuit goes beyond the maximum rated working current, the heat-resistant metal melts or severs, which disrupts the flow of current and thus protecting the circuit. The device also features a high-temperature limiting time-delay circuit, which ensures that the fuse does not open during short-term temperature and loading variations.

Fuses are typically used in a wide range of electrical applications, from residential to industrial. Although the 7100.1113.13 application field and working principle fuse is primarily used in specific industrial settings, it can provide excellent protection against overcurrents and inrush currents. By providing a low-impedance path to allow current flow and by containing a heat-resistant protective element, this type of fuse is both effective and reliable when it comes to protecting circuits and equipment from damage.
