How to calculate how many specified fuses are replaced?
Use the current 1.5 to 2.5 times. The power of all electrical appliances is added to the total power, such as 1000 watts to remove the voltage 220 as an example equivalent to 4.5 amp. Its 1.5 to 2.5 times is to replace the specifications of the fuse 6.75 to 11.25. Sometimes the national standard standards do not just go up to the first level (it should also refer to the fuse current).
The voltage of the circuit must be less than or equal to the rated voltage of the fuse. That is to say, if the voltage of the circuit is 125V, then both fixed fuse rated voltage 125V and 250V can be used. If the circuit voltage is 250V, only 250V fuses can be used instead of 125V purse.
U.S. standard: The rated current of the fuse (Iraated) = IN/0.75
European standard: Iraated current (Iraated) = in
We are company generally requires customers to provide us with the corresponding rated voltage, rated current, breakpoint capabilities and dimensions, as well as whether there are other temperature rise requirements.After confirming these important parameters, we will match the appropriate fuse, and finally provide the specification to the customer to determine.
