When selecting a fuse, you must consider several elements

When selecting a fuse, you must consider several elements

Answer:

The voltage of the circuit must be less than or equal to the rated voltage of the fuse.

That is, if the circuit voltage is 125V, then the choice of the rated voltage 125V and 250V fuse can be used. If the circuit voltage is 250V, it can only use 250V fuse, and can not use 125V fuse.

This is the main condition to determine the choice of fuse specifications, according to this condition can initially determine the fuse specifications.

Taking into account the actual use and laboratory differences, the use of ambient temperature of 25 ℃ under the conditions,

The rated current of the fuse is confirmed at room temperature of 25 degrees, and the ambient temperature has a great impact on the rated current of the fuse. When the ambient temperature is higher than 25 degrees, the rated current value of the fuse will be attenuated, Below 25 degrees, the rated current value will be "added value"
