Works for AC units
Changed my bad fuse with this one for my AC unit and it worked perfectly. My advice is to search online if this one is compatible with your unit and if so go ahead and get it. Get it quickly and saved me a lot of money paying someone to do it for me.

Keep the blower going!
The home blower suddenly stopped and it is cold outside. Made some checks and found one fuse was bad. It's getting cold so another fuse is needed soon. Amazon quickly came through with the fuses. They were installed and we are warm once again. Thanks Amazon.

Good generic fuses that cost less, work OK.
Fuses are "Bullet" brand rather than "Bussmann" as described. Not in original packaging. Work OK. About 1/2 the price of home improvement centers. Good to have some extra fuses as backups for my A/C during extreme heat.

Got the job done!
My situation... 1. Fan blowing warm air 2. AC unit outside is not even coming on 3. Opened the AC unit and saw that all the capacitors looked good, no bubbling capacitors 4. Checked the fuses in my disconnect and saw that 1 was bad. These fuse never arrived from Amazon unfortunately, but I'm leaving a review because I got the exact ones from my local HD, and my AC is up and running.

Got my A/C running again
These come in handy in the hot summer months here in Phoenix when our A/C blows a fuse. Simple to replace and gets the A/C back up and running in no time.
