Detailed explanation of the working principle of temperature controlled fuses The characteristic of a temperature controlled fuse is that it will automatically disconnect the circuit when the current is too high or the ambient temperature is too high, in order to protect the components in the circuit from damage. Its working principle is based on the thermal effect. When the current or temperature exceeds the set value, the thermal sensitive material inside the fuse will undergo corresponding changes, causing the fuse to disconnect the circuit. Temperature controlled fuses are widely used in household appliances, automobiles, electronic devices, and other fields. When the ambient temperature reaches a certain value, this thermosensitive material will rapidly expand and damage the internal circuit, achieving an open circuit. The structure of a temperature controlled fuse mainly consists of a housing, a thermistor, contacts, terminals, and other parts. The shell is a sealed compone
Introduction to Temperature Control Fuse Models and Specifications A temperature controlled fuse is a type of fuse that is sensitive to temperature changes and can automatically open or close circuits based on changes in ambient temperature. Simply put, its main function is: when the ambient temperature rises to a certain level, the temperature control fuse will automatically disconnect, cutting off the circuit; When the temperature drops, it will automatically close and restore the circuit. A temperature controlled fuse is composed of fuse blades, reactance, and metal contacts. When the temperature rises, the fuse will expand, pushing the reactance to move, causing the metal contacts on the reactance to separate, thereby disconnecting the circuit. When the temperature drops, the fuse blade shrinks, the metal contacts on the reactance make contact, and the circuit recovers. The common parameters of temperature controlled fuses are: Rated current: indicates the maximum current tha

Plug-in fuse Plug in fuses play an important role in circuit protection. Structurally, a plug-in fuse typically has a plastic casing that contains a meltable metal sheet inside. This design allows it to be easily inserted into the corresponding fuse holder, making installation and replacement relatively convenient. The outer shell not only serves to protect the internal metal sheet, but also to some extent prevents the risk of electric shock to the user. The working principle is based on the heat generated when current passes through a metal sheet. When the current in the circuit exceeds the rated current of the plug-in fuse, the metal sheet will quickly heat up. When the temperature reaches the melting temperature of the metal sheet, the metal sheet will melt, thereby cutting off the circuit. This circuit breaker mechanism can effectively protect electrical components in the circuit from damage caused by excessive current. Plug in fuses are widely used in the automotive industry
Miniature fuse Miniature fuses are an important component in the field of electronic circuit protection.
