Electrical fuse, also known as thermal fuse, is a safety device that controls and protects electrical circuit. The primary purpose is to protect the electrical circuit against overcurrent, high current or short-circuit. In a circuit, an overload circuit element such as wire, relay, or switch will protect the circuit; however, these elements can melt with an overcurrent situation. The fuse will instantly open the circuit when an overcurrent situation occurs and protect the circuit. 20ET type fuses are widely used in the application of modern electronic equipment and are essential for the normal and safe operation of the equipment.

20ET fuses are usually used in electrical systems with a rated voltage of 250V and a rated current of 20A or less. It is a type of chip-sized miniature Cartridge Fuse, with a compact structure and a built-in overcurrent and short-circuit protection element. It has the advantages of a small volume, high safety, easy installation, and a wide range of applications. 20ET fuses can be used in many applications, such as home Appliance, Electronic Device, Industrial Equipment, and Car Electronics.

The working principle of 20ET fuses is simple and effective. An element of the fuse, usually a wire, strip, or ceramic tube with a helical groove, is connected in series with the circuit. When the current exceeds the rated value, the element will be broken and the circuit will be broken, the current is interrupted. The fuse only allows the normal current rating to pass through and can support up to 20A, ensuring reasonable and effective current protection. The 20ET fuse has a metal film that increases its current rating, reduces the size of its element, and increases its melting speed.

20ET fuses have a wide range of applications. They are widely used in home Aplliances, such as refrigerators, washing machines, air conditioners, and microwaves; in Electronic Devices such as TVs, calculators, cameras, and radios; in Industrial Equipment, such as electric motor control systems, switching power supplies, and telecommunications equipment; in car electronics, such as power switching gear, navigation systems, and audio systems.

20ET fuses ensure that the circuit remains safe and secure in the event of a fault, while the current flowing through the system remains at a safe level. They are designed to provide protection against overcurrent and short circuit for all types of electrical and electronic equipment. They are made of high temperature resistant ceramic body, which ensures excellent stability and reliability and can withstand high temperature. They have strong current capability, high degree of overload protection, low contact resistance and fast response time.

In conclusion, 20ET fuses are an essential part of modern electronic equipment. They provide reliable and effective protection against overcurrent and short-circuit. They are small in size, easy to install, and have a wide range of applications. Their high temperature resistant ceramic body ensures excellent stability and reliability, and their strong current carrying capacity, high degree of overload protection, and low contact resistance make them the ideal components to protect electronic equipment against damage from overcurrent.
