5X20 mm 125 V/250 V Keramiksicherungen mit Blei, (3/16 Zoll X 3/4 Zoll)
Kategorien: Elektro-Sicherung, Sicherungskastenhalter
Stichworte: Keramikrohrsicherung, elektrische Sicherung, Glasrohrsicherung
5Auswahl und Anwendung von x20-mm-Keramiksicherungen: Bei den Sicherungstypen handelt es sich üblicherweise um Drahtsicherungen, Glassicherungsrohre, Quarzsandsicherungen, insert fuses, usw. 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. Zum Beispiel, hair dryers, elektrische wasserkocher, electric irons, thermal relays, usw.
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.
