1 Answers
To determine if a car fuse is blown, you can inspect the fuse box. A blown fuse will have a broken connection in the middle, while a good one will remain intact. Below is relevant information about car fuses: 1. Function: A car fuse is a type of current protection fuse. When the circuit current exceeds twice the rated current of the fuse, it will melt within seconds, serving as circuit protection. Commonly used for overcurrent protection in automotive circuits, it is also applied in industrial equipment overcurrent protection. 2. Classification: Fuses can be categorized into blade-type automotive fuses (by size: mini, standard, and maxi fuses); glass tube automotive fuses (by size: 5*20mm; 6*30mm fuses); bolt-type automotive fuses (by size: mini and maxi fuses). Current ratings include: 1A, 2A, 3A, 5A, 7.5A, 10A, 15A, 20A, 25A, 30A, 35A, 40A, 50A, 60A, 80A, 100A. In blade-type automotive fuses, each color represents a different current rating. Certifications include: UL, CSA, ROHS.
