Well Geebo is a bit off... A slow blow element fuse is a dual feature fuse used primarily for motor starting and stopping. This provides protection during starting of motors, when they draw considerably more current than during run time. They also provide quick protection for immediate response as a immediate blow during a short out situation. A slow blow fuse only provides the latter. Why use quick blow? They are a fraction of the price of dual component. They are differences in reaction time and application. Slow blows are across the world used on motor or relay circuits to allow time for peak current to fade before mundane operation. Quick blows are used on safety circuits where over current may wreak significant damage or is a fire hazard.
Answers: a "slow-blow" rating, means that it can handle moderately lofty currents for a short time without injury. Such a fuse might be used in an appliance containing a motor. If the motor is rated to consume 2 Amps during continuous operation, it could be protected by a slow-blow fuse. When the motor is first turned on, it will draw much more than 2 Amps for a few second, and the slow-blow rating of the fuse ensures that the fuse doesn't blow every time the motor starts. A quick blow fuse is in truth just a standard fuse designed to blow instantly. Hope this helps
