About this deal

Occasionally, as in the image above, a by-pass wire across the spring is used to adjust the characteristics of the fuse. The combination of lump and spring, with its relatively high thermal mass, also allows the surge to pass, but provides the protection for longer term but lesser overloads. While all this discussion on types of fuses is very instructive, I wonder whether it answers the underlying question. Packaging Close Λ After unpacking, carefully inspect the various random accessories and parts in the package to avoid omissions.

He found that a spot (the 'M' spot) of solder on a silver wire element did not affect the short circuit performance, but it did reduce the time to blow on a sustained lower current. In this case, at the lower temperature of the wire, the solder diffused into and alloyed with the silver to create a region of high resistance in the spot, which would glow red hot, with the wire rupturing next to it. Put a T in there, and things can suffer a bit of damage if there IS a problem, because the fuse leaves power applied for rather longer. The third part of the element is a stout spring of relatively high resistance material, helping to heat up the lump, and pulling it rapidly apart when it melts.The simplest is to increase the thermal mass of the element, using a thicker, and therefore longer wire (to get sufficient resistance to heat up), wound round an insulating core, with careful control of the spacing for consistent operation.

You can change your choices at any time by visiting Cookie preferences, as described in the Cookie notice. And do you think the power outage could do some damgae to the amplifier components even after blowing the fuse? If fast-blow is used instead of slow-blow, there will be no damage, but fuse consumption can increase, which is usually preferable to equipment damage. In a fast acting fuse the thermal dissipation in the wire acts to melt the wire portion that is carrying it. I've seen it suggested by some sites only that slow blow use lower melting temperature materials - but this is not a certainty.I had one blow in my amp and I know its 125v 5a, but i'm not sure if it is a slow blow or fast acting fuse. Electrical Engineering Stack Exchange is a question and answer site for electronics and electrical engineering professionals, students, and enthusiasts. There are many variations on this design and it gives manufacturers a lot of parameters for adjusting the fuse characteristics. New: A brand-new, unused, unopened and undamaged item in original retail packaging (where packaging .

Incidentally, A good design should have F or T plus the fuse rating marked on the PCB where the fuse holder is.To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Widely used in power supply, switching power supplies, computers, chargers, telephones, household appliances, communication products, all kinds of instruments and electronic components, electrical products, is indispensable in electrical products safety accessories. This is similar to an F fuse working at well below its rating, so it will not protect against overloads close to the rated current.
