Definition- What Is The Function Of A Fuse?










The purpose of a fuse, or similar circuit protector, is to protect electrical devices and components against over-currents and short circuits. Specifically, the device prevents overheating or fire in the event of a fault. A fuse, therefore, can be considered as performing two functions: to establish the maximum continuous fault current and to open the circuit when the fault current exceeds the maximum continuous fault current.
