10Pcs T3.15AL250V 5x20mm 3.15A 250V Slow Blow Fuse T3.15AL Glass Slow-Acting Time-delay Fuse (3/16 in x 3/4 in)

Good value, did the job well

Fits fuse holder. Have not had any issues.

Needed these to replace a fuse that I blew on my solar system monitoring module. I accidentally crossed the polarity when making a change and could not monitor my solar installation. Ordered these, they arrived in a day and now all is working again. The fuses came in a 10 pack for future replacements. They are a great value for the price, and now I have some to cover possible blown fuses in the future. Glad I bought them and they get 5 stars.

Good

I had a fuse blow on my RV range hood. I purchased the regular fuse initially and it blew almost immediately. The slow blow fuse makes all the difference for my application.

Needed a fuse for a speaker that blew out prior to a graduation party. Exactly what I needed and Fast shipping

I am pleased with these fuses and the price was good.

Need fuses really bad swimming pool was down they were what I need to get up and running Thanks

Although the fuses I received were not spiral wound around a white core, they are indeed Time Delay fuses. Time Delay fuses are made in different ways to withstand a short surge of current but to blow when current above the rating, in this case 3.15 A, is sustained. Some look just like a fast blow fuse with a wire between the end caps. Some have a flat ribbon between the end caps. Some have a flat ribbon with a narrow section in the middle. Some are spiral would on an insulating core as is shown in the picture for these fuses. When designed properly, they all function similarly. In this case the photo in the listing shows a spiral wound wire on a white insulating core, but the fuses that I received had a straight wire so that they look like a fast blow fuse. However, the end cap is clearly engraved with T3.15AL250V, meaning that this is a T=Time delay fuse rated for 3.15A with a L=Low breaking capacity and use in circuits up to 250V. Low breaking capacity means that the fuse is rated to not physically break (e.g. arc, break, burn) at currents up to 35 A (10x the rating or 35A, whichever is higher). Not all fuses contain the breaking capacity marking, which is commonly L for Low or H for High for these small tubular fuses. I used this fuse to replace a T3.15A250V (no breaking capacity marking on the original fuse). It works fine even though my original fuse was spiral wound and this replacement is straight wire. I would buy again and recommend for anyone needing a T3.15AL250V glass tubular fuse that is 5 mm dia by 20 mm long.

They work and are packaged well.

One of our LG Inverter Heat Pumps stopped working because of one of these fuses, I was able to get it working with a 2A fuse but was happy to Amazon carried these. I put one in and can confirm that it fixed our issue, amazing how something worth 10 cents can make a $6,000 Heat Pump stop working.

I bought this and tested on my Rockville speaker it works. Thanks Amazon and your supplier.

Quantité importante quand on en a besoin que d'une seule, merci Amazon pour l disponibilité de ce produit relativement rare.
