6x25mm Cartridge Slow Blow Ceramic Tube Fuse Link 20A 75V With Copper Silver Plated Cap

Fuse is a kind of component which is sensitive to current, when the fault current occurs to over the rating current. the fuse will melt to avoid the further damage to the electric equipment. To select an appropriate fuse for a particular application seems very important, we can design a fuse according as below mentioned steps:

Fuse selection-theory:

A. The first consideration, where do you intend to approve your device, For the different design view,there are two kinds of standard system.

B. Construction & Size: Fuse is a changeable component, it is specified in the relevant standards, the a ppropriate size and construct ion is another design f

C. Voltage rating (V): D. Current Rating: E. Breaking capacity (interrupting rating) :

F. Ambient temperature : G. Fuse Characteristics: H. l2t value: I. Pulse cycle withstand capability:

Mainly used for 5G communication base stations
