2020.0001 application field and working principle

A fuse is an electrical protection device. It is composed of a shell, contacts, lead and fuse element. The fuse element and the contact function as a switch, which can make the circuit in the working state or disconnect state. In the case of abnormal current, the fuse element is damaged or burned out to ensure that the circuit is disconnected reliably.

The 2020.0001 application field is mainly in the field of emergency power supply and industry, such as computer peripheral power supply, audio equipment, portable medical equipment power supply, voltage stabilizer, power supply protection, solar panel power supply, electrical equipment, instrumentation protection, etc. It is widely used in the fields of power, electrical appliances, communications, metallurgy, petrochemical industry, automotive electronics and other industries.

The working principle of 2020.0001 is based on the Joule heating effect. When the rated current passes through the fuse element, the heat generated by the resistance of the nickel-chromium alloy wire will cause the internal temperature of the fuse element to rise and start to melt. When the temperature of the fuse element reaches the melting point, the fuse element begins to melt. At this time, the current is interrupted, and the circuit is disconnected.

In addition to this kind of ordinary fuses, there are some miniature two-stage fuses, multi-element fuses, fast-acting fuses, re-settable fuses, micro-fuses, etc. These types of fuses have higher requirements for currents and have special functions. The fast-acting fuse is characterized by its high response speed and can quickly isolate the circuit when over-current occurs, protecting the circuit equipment.

2020.0001 is an important protection component in the circuit that plays a very important role in the safety protection of the circuit. Implementing effective power supply safety protection is beneficial to reduce equipment failure and production delays.
