5X20mm 125v/250v帶鉛陶瓷保險絲, (3/16 英寸X 3/4 英寸)

5x20mm Ceramic Fuse selection and application: The types of fuses are commonly wire fuses, glass fuse tubes, quartz sand fuses, insert fuses, 等. 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. 過流保護: 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, 風筒, 電熱水壺, 電熨斗, thermal relays, 等.

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 (額定電流), fuse current, short-circuit current, and impact current. Its rated current is generally 1-1.2 times the current of the protected circuit.
