A standard fuse will blow in just milliseconds when excess current flow or a short is detected. A time delay fuse on the other hand may take 5-10 seconds to blow under the same conditions. You would want to use a time delay fuse in a device that uses lots of current at startup but then uses less after it is started. An electric motor or compressor is an example.
we use a time delay fuse at furnace area where heaters are used ect,
The time delay fuse allows a momentary overload due to startup current.
There is no difference. Slo-Blo is just a trademarked name for a time delay fuse.
A time delay fuse will allow for a temporary spike in the current (up to 100 or 200% of the fuse rating), such as when starting a motor. A regular (non-time delay fuse) will not allow for any spike over the current rating of the fuse. If you have a motor that pulls 2 amps while running, but pulls 6 ampls while starting, then you will want to use either a 6 amp non time delay fuse, or a 2 amp time delay fuse. If you are talking about pyrotechnics, a time delay (properly called a slow burning) fuse will give you more time to run for cover.
A time delay fuse will not blow at the first sign of an overload. It will delay blowing just long enough to allow a motor to start or a compressor to startup.
Time delay fuse.
Yes, and you should use a time delay fuse.
No, use a standard fuse.
time delay
The information of, if the fuse is a slow blow or not, is printed on the fuse. In electrical terminology it is known as a time delay fuse. Smaller glass envelope time delay fuses will have a spring mechanism that can be seen through the glass envelope. Time delay fuses are used in circuit that have a high inrush current when the device is first switched on. A good example of this would be an electric motor. The bead of solder on the end of glass fuses is how the spring is supported to the end cap of the fuse.
gG FUSES IS FAST ACTING BUT THE mA FUSES ARE TIME DELAY FUSES
Check it with an OHM meter for continuity.
