When the current fuse will increase to a certain height and a certain heat at a certain height and a certain heat, the current fuse will cut off the current, thereby protecting the safe operation of the circuit.
Current fuse manufacturer
1. Dongguan Gongfu Electronics Technology Co., Ltd. is a company that integrates circuit protection elements in the development, manufacturing, and supply of circuit protection elements in Dongguan City, Guangdong.There are many types of fuses produced by this company and rich in types.At the same time, their products meet ROHS environmental protection requirements and can be used with confidence.2. Shenzhen City Power Tong Industrial Co., Ltd. This is a company specializing in the development, production, and sales of patch -in plug -in fuses and current fuses.The biggest feature is that it can provide technical solutions, and production can be customized according to the special needs of customers.
Current fuse price
The current price fuse in the market is generally between fifteen and 20 yuan.
Current fuse standard
The current fuse is usually divided into several types: UL/CSA specifications, IEC specifications, and so on.Generally, the UI specification standards can maintain the working for more than 4 hours, and the rated value of the fuse current will not be within 110%, and the current with a rated value of 110%cannot be exceeded.The IEC regulations generally say that the fuse can maintain the work for more than 1 hour, and the rated value of the fuse current is within 150%, and the current with a rated value of 150%cannot be exceeded.
Current fuse principle
The so -called current fuse is actually a wire that can be melted.The resistance in this wire is much higher than in the ordinary wire. The principle is that when the circuit occurs in short circuit, the excess current will pass through the fuse. At this time, the temperature of the fuse will rise and the fuse will be melted.It is also cut off the power to prevent the current from further damage.
