Power circuits and high-power equipment used by the fuse, not only three parts of the general fuse, but also arc-extinguishing device,
1. According to the form of protection, can be divided into: over-current protection and overheating protection.
When the current between the conventional non-fusing current and the rated breaking capacity (current) specified by the relevant standard acts on the fuse
General fuse consists of three parts: one is the melt part, it is the core of the fuse, the role of cutting off the fuse, the same type,
When the current flows through the conductor, there is a certain resistance to the conductor,
Mark most fuses with markings on the body or end caps, indicating their rating.
1, strip Filiform.
Early original type fuse, directly with screw lock, used in various sizes of old switch, socket.
Automotive Chip Fuse Vicfuse
When the circuit fails or is abnormal, with the current rising, and the increased current may damage some important parts of the circuit, it is possible to burn the circuit or even cause a fire.
Fuses are mainly composed of 3 parts of the melt, shell and support, in which the melt is the key element to control the fusing characteristics.
1. Plug-in fuse: It is commonly used at the end of the line at the voltage level of 380V and below, as a short-circuit protection for distribution feeder or electrical equipment.
Fuse refers to when the current exceeds the specified value, the heat generated by itself causes the melt to fuse, disconnecting the circuit of an electrical appliance.
