How do I know what kind of fuse I have?
Look for “Class G” printed on the fuse. These fuses can be recognized by either their round shaped bodies with or without blades. Look for the wording “One Time Fuse” printed on the fuse. These fuses can be recognized by a removable slotted end cap that can be removed so that the fuse material can be replaced.
What products have fuses?
Automotive style fuses are used extensively in cars, trucks buses and off-road transportation equipment to protect the cables, wires and electrical components that supply electrical power to operate lights, heaters, air conditioning, radios, power windows and other electrical accessories.
Are all 15 amp car fuses the same?
Not all car fuses are the same, and most cars have multiple fuses of varying sizes for different electrical components. When you are replacing a car fuse, it is essential to replace the blown fuse with a new one of the same type and size. You should also never replace a blown fuse with one of a higher amperage rating.
What do you need to know about fuses?
About this guide Fuses are current-sensitive devices that provide reliable protection for discrete components or circuits by melting under current overload conditions. Choosing the right fuse for your application can be an overwhelming, time-consuming process, even for a seasoned electronics design engineer.
What are the markings on a cartridge fuse?
Note: Many small cartridge fuses will have additional markings stamped on the end caps. These are usually either; a series number, a part number, or product approval markings (refer table 3 below). If you are unable to identify the fuse, please contact us.
What should the rated current of a fuse be?
The rated current (I rat) of a fuse link should approximately correspond to the operating current of the device or assembly unit which is to be protected (in accordance with the ambient temperature and rated current-definition, which means the permitted continuous currents).
What is the IEC safety standard for fuses?
IEC 60127 is the safety standard for fuses destined for international use. Fuses in accordance with IEC 60127 can be operated continually at 100% of the rated current value whereas fuses in accordance with UL 248 can only be operated continually at 75% of the rated current value.
