You can substitute a higher voltage rating for a lower one, but not the “other way” around. The 250 volt rating means
the fuse will safely open a 250 volt circuit without “exploding”
or developing an interal arc which could maintain current flow longer than would be safe.
What is the difference between 240V and 250V?
If you live in a country where the main line provides
220
– 240V, the amplifier will work in the amount of power (Amps) that the cable can handle. The 250V is the maximum voltage for which you need to use it.
How many amps are in 250V?
The amp rating of a Carling switch is the maximum current in amperes the switch will carry continuously. So, in the example below the maximum amp rating for this switch at 250 volts AC (VAC) is
10 amps
; the maximum amp rating at 125 volts AC for the same switch is 15 amps.
What is the difference between a 125V and 250V fuse?
For example, a 125V fuse can be replaced with a
250V fuse of equal amplitude
while the voltage of the application is 250V or lower, but a a 250V fuse can’t be replaced with a 125V fuse of equal amplitude if the voltage of the application exceeds 125V. …
Can I use a 32 volt fuse in place of a 250 volt fuse?
Question: Will this 250v 4 amp fuse work to replace a 4amp 32v fuse (in an old amplifier/receiver)? Answer: 250V is the max current the fuse can take,
it is fine as long as that rating is at or above the current being passed through the fuse
, in this case 32V.
How many amps is a 250v fuse?
Semiconductor Fuse – 250 Volts
The 250 volt semiconductor fuse is a current limiting, very fast-acting, fuse rated to 250 volts AC and up to 250 volts DC. Current ratings range from
1 to 2,500 amps
. The maximum interrupting rating, is 200,000 amps AC and 100,000 DC.
How many volts is a 20 amp circuit?
20-amp
120-volt
circuit: 20 amps x 120-volts = 2,400 watts.
Can a 240V appliance run on 250V?
The voltage listed is the maximum rated voltage that should be applied to it. Therefore,
it’s normally possible and safe to plug a 240v into a 250v
receptacle.
Can I plug a 250V into a 240V?
If the cord has “250V” printed on it and your mains power is between 220V-240V, then
go ahead and plug it in
. You won’t have any problems as long as the 250V power cable fits into your 220V-240V wall power outlet and into the amplifier.
Can you use a 250V?
250V is
the max VOLTAGE the fuse can take
, it is fine as long as that rating is at or above the VOLTAGE being passed through the fuse, in this case 32V. Fast blow can be used but will fail quicker, Slow blow fuses are designed to allow higher currents for a longer amount of time.
What does the T stand for on a fuse?
T =
slow burn fuse
. F = fast acting fuse. TT = very slow burn fuse. FF = very fast acting fuse.
Can I use a 250v fuse instead of 12V?
However, for less than 12V, or if you need a very precise voltage level use fuses specificaly adapted.
Yes
, you can use them, The amp rating does not change.
Does voltage rating matter on a fuse?
The voltage rating of a fuse
must be at least equal to or greater than the circuit voltage
. It can be higher but never lower. … If a fuse is used with a voltage rating lower than the circuit voltage, arc suppression will be impaired and, under some overcurrent conditions, the fuse may not clear the overcurrent safely.
Does voltage matter on a glass fuse?
Is the voltage rating important?
Yes
, very important! The voltage rating of the selected fuse must be greater than or equal to the circuit voltage. Since fuses have such low resistance, the voltage rating becomes critical only when the fuse is trying to open.
Can I replace a fuse with a lower amp?
Do not use a fuse with a lower rating
– don’t put a 20 amp fues in a 30 amp circuit–because it probably will blow prematurely. Conversely replacing a 20-amp fuse with one rated at 30 amps is dangerous because it may not blow soon enough and damage an electrical component or start a wiring fire.
Can I replace a ceramic fuse with a glass fuse?
You can replace a glass fuse with ceramic, but
not recommended to replace a
ceramic with glass. Be sure they are the same voltage and amp rating, slo-blow, etc.
