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.
It depends on the precise type of slow blow fuse, but in general terms a fuse with a slow blow characteristic will take longer to operate (blow) at high overload currents than one with a normal characteristic. For low overload currents it will operate in about the same time as a normal fuse.
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.
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.
another name could be "dual-element fuse" as these are the slow-blow type.
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.

Slow burning fuse usually to alot time to evacuate an area
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.
It should be a 1.25 amp (1250ma) "slow-blow" fuse.
A T5AL is a tubular 5 amp 20mm x 5mm Slow Blow Anti Surge glass fuse.
No. A slow blow fuse is intended to survive a short overload from the startup of a piece of equipment, usually a motor or power supply. If you use a fast blow fuse in this application, it will tend to blow unexpectedly.Motors usually pull four times their rated running current on startup, but only for a very short period of time. The slow blow fuse, or slow trip circuit breaker, is designed to handle this. Similarly, power supplies need to charge the primary filter capacitor from zero voltage in one line cycle on startup. Worst case is turning on the power switch at the peak of the line cycle. Inductance of the transformer (if present) and dynamic resistance of the diode mitigates this, but there is still a larger than normal current transient. Again, the slow blow protective device allows this in the short term.Hy i'm GbRlEuEeN, i used f10a(fast) fuse to replace t5a fuse(slow) but was on audio sistem(subwoofer) and i will change back as soon il get the t5a. ( i tryed f5a first but blowed instant at power up.
