If the fuse is labelled F it is fast-blow or T OR S it is slow-blow, the letter should be on the metal cap on the ends of the fuse.
no A FRN fuse is a slow blow fuse where an non is a fast blow fuse. In a pinch a slow blow fuse can be use in a fast blow circuit but not the other way around.
Any piece of machinery that is designed to use a fast blow fuse should only use a fast blow fuse. For safety reasons this could save your life instead of taking it.
The time it takes for a fuse to blow, either "fast blow" or "slow blow" is determined by the design of the fuse and is described in a table or graph provided by the manufacturer. In general, the higher the applied overload current, the faster the fuse will blow. Fast blow fuses can open in milliseconds, slow blow fuses can open in several seconds. The fuse used depends entirely on the application and what kind of circuit it is protecting.
The fast blow fuse will generally only have a straight wire between the terminals, while the slow blow version will have part of that wire coiled up as a spring.
Typically the "F" stands for "Fast Blow" or "Fast Acting". A "T", as in T6A, would mean "Time Delay" or Slow-Blow. So, an F6A 250 is a Fast Acting (Fast Blow) 6 Amp 250 Volt Fuse.
You can it will be safe and no damage will result. However it will blow sooner than the intended fuse would, so the amplifier will no longer have its full normal operating range.
slow
yes it can but it may not protect as well the f5L is a fast blow fuse made to react quickly to the overcurent
Check to insure that you are replacing the fuse with the same fuse size and type (fast blow fuses don't substitute for slow blow.) If this is ok the either the pump relay or the pump is going bad and drawing too much power for the fuse to handle.
Blow My Fuse was created on 1988-09-19.
Slow blow Fuse that can withstand a heavy current (up to ten times its rated value) for a small period of time before it opens. Normally used for inductive loads like fans, transformers, etc. Fast blow Fast-acting fuses have no intentional built in slow-blow and are used in circuits without transient inrush currents. Fast-acting fuse opens on overload and short-circuits very quickly. This type of fuse is not designed to withstand temporary overload currents associated with some electrical loads.
Make sure that the fuse is the right size and the right type (slow blow or fast blow.) It the fuse is right then the electrical system will have to be checked to see what is drawing too much power.
