DZ27F20 Application Field and Working Principle DZ27F20 is an electromechanically operated fuse, which is designed to protect electrical systems or machines from over-currents, over-temperatures and surges. It is mainly used in industrial, commercial, telecommunication, and automobile protective circuits. DZ27F20 can be used in form of a sheath element in combination with other types of circuit protection, such as circuit breakers. It is primarily designed for frequency below 2kHz and rated voltage up to 1000V.ApplicationsDZ27F20 is a commonly used fuse element and suitable for many applications in different electrical and electronic circuits. It can be used in industrial, medical, communications and automotive systems.Industrial applications: It is widely used in industrial machinery, communications equipment, security systems, and other high temperature equipment.Medical applications: It can be used in medical, hospital, lab, and other medical facilities.Communication applications: It can be used in cable boxes, routers, and other communication packages.Automotive applications: It can be used for automotive lighting, battery charging, and other automotive circuits.Working PrincipleDZ27F20 is a type of fuse that depends on its melting current for protecting the circuit from over current and over temperature. Its working principle is as follows:The fuse element of the DZ27F20 consists of a thin metallic strip that is inserted inside a ceramic or plastic body. The fuse element is connected in series to the line which is to be protected and is protected with an over-current protective device. When the current exceeds this safe threshold, the fuse melts and the current is disrupted and the protection is provided.The current rating of the fuse element is determined by its length, thickness, and the material it is made of. The fuse body itself acts as a heat sink, allowing the fuse element to cool down when a high current passes through it.AdvantagesThe main advantages of using DZ27F20 fuses is that they provide an extra layer of protection to the circuits they protect and can be used a wide variety of applications. They are also relatively inexpensive compared to other types of fuses and are available in a variety of sizes and ratings. In addition, DZ27F20 fuses are easy to install and maintain.
