Fuses are electrical safety components installed in electrical systems to protect against overload or short circuit conditions in the system. BK/GBB-7-R fuses are a type of fuse specifically designed to protect specific applications from damage. These fuses are designed to handle high levels of amperage and are preferred for use in industrial and other demanding applications.
Application Field
BK/GBB-7-R fuses are typically used in situations where the application is exposed to high levels of current and voltage, including, but not limited to, industrial machinery, power systems, household appliances, electrical motors, and electronic equipment. It is also commonly used in distribution systems, such as in switchgear and power supplies, as its high amperage capacity and small size makes it ideal for these applications.
Working Principle
BK/GBB-7-R fuses are designed with a braided wire link that melts when the current passing through it is higher than the rated value of the fuse. This link, or element, melts when the current exceeds the threshold, thereby disconnecting the electrical circuit. Single action fuses are designed so that only the braided wire melts, while dual action fuses contain a small contact that works in conjunction with the element to ensure a quicker shut off time during a fault condition.
To prevent false tripping, BK/GBB-7-R fuses feature an iron core that is designed to hold its shape when exposed to high or low amperage levels. The iron core, which surrounds the element, helps by providing an alternative pathway for current to pass through the fuse. The result is a longer response time in the event of an overload or short circuit, which can be vital in applications that need to be kept running no matter what.
To ensure that the fuses are used correctly, it is important to match the fuse\'s rating to the application. BK/GBB-7-R fuses are available in ratings up to 1600A, and the correct rating must be selected to ensure that the correct protection is provided.
Fuses play an important role in electrical systems, and BK/GBB-7-R fuses are a great choice for applications that require a combination of high amperage ratings and low response time. By understanding the applications the fuse is intended for and the working principle behind it, you can ensure that your system is properly protected.
