5X20mm 125v/250v Ceramic Fuses with lead, (3/16 inch X 3/4 inch)
5x20mm Ceramic Fuse selection and application: The types of fuses are commonly wire fuses, glass fuse tubes, quartz sand fuses, insert fuses, etc. The different forms have different usage environments.
The rated current of 5x20mm fuses with different wire diameters is also different.
When selecting and adapting fuses, they will be affected by voltage and current, resulting in differences. From the voltage type: generally there are three types of high-voltage fuses, low-voltage fuses, and electronic circuit fuses. Differentiate from the current level: generally ranging from 0.5A to 100A.
In the process of selecting fuses, in addition to the above content, two types of overcurrent protection and overheating protection should be distinguished. Overcurrent protection: It is the most commonly used current limiting fuse. Overheating fuse: It plays a protective role when the temperature is too high. It is generally used in electrical appliances with heating and temperature control requirements. على سبيل المثال, hair dryers, electric kettles, electric irons, thermal relays, etc.
The configuration of the fuse, its current size is the key measurement indicator of the protection function. Attention should be paid to the four current values of normal current (rated current), fuse current, short-circuit current, and impact current. Its rated current is generally 1-1.2 times the current of the protected circuit.

Custom slow-blow F1A/250V 3×10 glass fuse with lead
The role of the 3.6x10mm fuse:When a circuit malfunctions or is abnormal, the current is constantly rising, and the increased current may damage some important components or valuable components in the circuit, or it may burn the circuit or even cause a fire. The 3.6x10mm fuse will cut off the current when the current abnormally rises to a certain height and a certain time, thereby protecting the safe operation of the circuit.
