Glass fuses have a low breaking capacity. It's easy to see when they're blown: the glass will be discolored and the filament broken. Replace yours today!

Ceramic fuses are high or low breaking capacity and can be used in many applications. Ceramic color can vary from a very light beige to dark gray.

Frequently Asked Questions

First things first, double check with other people who live or work with you. Oftentimes someone tries to be helpful and collect your packages but then forgets to tell you!

We also recommend asking any available neighbors if they might have accidentally received your package. If you have a cluster box or parcel locker sometimes your mail carrier can leave the key in the wrong mailbox.

If you know your mail carrier, ask them! They may remember delivering your package and have more detailed information about the delivery.

Most of our packages are shipped in yellow bubble mailers or white FedEx envelopes and some will be in brown boxes. 

When you've tried all of those options but the package is still missing please contact us! We can open an investigation with the Postal Inspectors in the case of stolen mail or file claims with other carriers. 

Let us know! Sometimes there's just a little delay between facilities but we can request a more detailed update from the carriers. Most packages won't have any issues getting delivered even with a 2 or 3 day gap of tracking movement. If it's been longer than that we'll contact the carrier for more information.

We will almost always be able to contact you when we substitute brands of fuses. The specifications will be exactly the same and we send only fuses that are identical in both fit and function. In a lot of cases, we are also able to offer discounts for switching brands. 

If you specifically want a certain brand we are happy to ensure that it gets sent or exchange the substitutes once you've received them. Please contact us with questions.

How are they different? 

1. Part number doesn't match

Depending on the manufacturer the exact part number will vary. Some manufacturers never include the blowing speed (T or F) and some don't use the breaking capacity either (L or H). This doesn't mean that the fuse has the wrong specifications! We order inventory very carefully and each fuse will have the correct specifications as noted in the product description. Check the packing slip and product label for the info!

2. Dimensions aren't the same

Fuse part numbers do not include any size information. Check out our buying guide for glass and ceramic fuses for info about dimensions: Glass and Ceramic Fuses
