Cylinder electric 250v 2amp DC fuse
DC Fuse function:
When the circuit fails or abnormal, accompanied by rising current, and the rising current may damage some important devices in the circuit or expensive devices, it is possible to burn the circuit or even cause a fire. If the circuit is correctly placed in the fuse, then the fuse will rise in the current to a certain height and a certain time, their own fuse cut off the current, which play a protective circuit safe operation

3, Structural features:
The structure of the power fuse is approximately the same as that of the fuse. It consists mainly of melt, shell and support 3 parts, in which the melt is the key component to control the fuse characteristics.
The material, size and shape of the melt determine the fusing properties. Melt materials are divided into low melting point and high melting point. Low melting point materials such as lead and lead alloys, the melting point of the low melting point, because of its high resistivity, so the melt made of larger cross-section, the fuse generated when the metal vapor more only for low breaking capacity of the fuse Device.
High melting point materials such as copper, silver, its high melting point, not easy to fuse, but because of its low resistivity, can be made smaller than the melting point of the melting point of small melt, fuse generated when the metal vapor less suitable for high breaking Ability to fuse. The shape of the melt is divided into filament and ribbon.
Changing the shape of the variable cross-section can significantly change the fusing characteristics of the fuse
4, The main advantages of fuses
A, Good selectivity Up and down fuse fuse rated current as long as the GB and IEC standards to meet the requirements of the overcurrent ratio of 1.6: 1 requirements, that is, the upper rated fuse current is not less than the subordinate of the value of 1.6 times, as the upper and lower level Selective cut off fault current;
B, Good current limiting characteristics, high breaking capacity;
C, Relatively small size;
D, Cheaper prices.
