What is the BTN fuse?
1 Answers
BTN fuse is the fuse for interior lights and automatic door locks. Here is extended information: 1. Introduction: The fuse (also known as current fuse) can melt itself to cut off the current when the current abnormally rises to a certain level and temperature, thereby protecting the safe operation of the circuit. 2. Function: The fuse, invented by Edison over a hundred years ago, was used to protect the expensive incandescent lamps at that time. With the development of the times, the fuse protects electronic/power equipment from damage caused by overcurrent/overheating, avoiding serious damage to electronic equipment caused by internal faults.
