5X20mm 125v/250v 带引线陶瓷保险丝, (3/16 英寸X 3/4 英寸)
5x20mm陶瓷保险丝的选择及应用: 保险丝的种类常见的是线状保险丝, 玻璃保险丝管, 石英砂熔断器, 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.

5X20mm Ceramic Tube Fuse Electrical Characteristics
In the process of selecting fuses, in addition to the above content, two types of overcurrent protection and overheating protection should be distinguished. 过流保护: 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. 例如, 吹风机, 电热水壶, 电熨斗, 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 (额定电流), fuse current, short-circuit current, and impact current. Its rated current is generally 1-1.2 times the current of the protected circuit.
