Description:
Direct insertion resettable fuse tube
Overcurrent protection
Short-circuit protection: When a short-circuit fault occurs in the circuit and the current suddenly increases sharply, the in-line self-restoring fuse tube will respond quickly. Its resistance value rises rapidly due to the heat generated by the large current and enters a high-resistance state, thus limiting the further increase of the short-circuit current and preventing damage to other components, lines and equipment in the circuit due to excessive short-circuit current, and avoiding fires, etc. More serious consequences. For example, in some simple household power socket circuits, if a short circuit occurs inside the socket, the in-line resettable fuse tube will act in time to cut off the circuit and protect the electrical equipment connected to the socket and the entire circuit system.
Overload protection: When the circuit load is too large and the operating current exceeds the rated current of the fuse tube but does not reach the level of short circuit, the direct-plug self-restoring fuse tube will also play a role. As the current increases, the heat generated by the fuse tube increases, which also increases its own resistance, limiting the current increase, protecting circuits and equipment from damage by overload current, and extending the service life of the equipment. For example, in the motor drive circuits of some small power tools, when the motor current increases due to overload or jamming, the in-line resettable fuse tube will automatically cut off the circuit to prevent the motor and drive circuit from burning out.
Automatic recovery function
Save replacement costs and time: Unlike traditional disposable fuses, after the fault is eliminated, when the temperature drops to a certain level, the internal conductive path will be restored, the resistance value will be reduced to the initial state, and the circuit will automatically recover. Normal conduction. This makes it possible to greatly save maintenance costs and time and improve the efficiency and reliability of equipment in some situations where overcurrent conditions occur frequently but you do not want to replace fuses frequently, such as industrial automation production lines, smart home appliances and other equipment.
Circuit stability maintenance function
Prevent the influence of current fluctuations: In some circuits that require high current stability, such as precision instruments and equipment, communication equipment, etc., in-line self-restoring fuse tubes can effectively suppress sudden increases or fluctuations in current. Even when there is a brief fluctuation in the power supply voltage or an instantaneous overcurrent situation in the circuit, it can act quickly and recover in a short time to ensure the stability of the current in the circuit, ensure the normal operation of the equipment, and prevent damage to precision components due to current fluctuations. , improve the stability and accuracy of the equipment.
Security function
Prevent potential fire hazards: By cutting off the overcurrent circuit in time, inserting the self-recovery fuse tube can effectively reduce the heat in the circuit caused by overload, short circuit, etc., reduce the risk of fire caused by overheating, and provide important protection for families, industrial places, etc. Safety guarantee, especially in some environments where people are densely packed or where flammable items are stored, plays an even more critical role.
Protect personnel safety: It can prevent the equipment shell from being electrified due to circuit failure and avoid electric shock accidents. In some electronic devices that are in direct contact with the human body, such as mobile phone chargers, electric shavers, etc., the use of in-line self-restoring fuse tubes can ensure the safety of users.
