This Bussmann FRN-R-45 is a time delay cartridge fuse built for circuits with motors, compressors, or pumps that draw a heavy surge on startup. The time delay design rides out that initial inrush instead of blowing, while still cutting power fast if a real overload or short develops. Rated 45A at 250V with a durable fiberglass tube and ferrule endcaps, it's UL Listed for dependable protection in air conditioners, well pumps, and other motor-driven equipment.

You're going to price-check us against Amazon, Home Depot, and Lowe's. Everybody does. Good — open all three tabs. We'll wait. Then look hard at what you're actually being handed over there.
On Amazon, start with these four questions before you click buy.
The brand name is on the listing. A different company is in the seller field. Those aren't the same thing, and the second one is who you're buying from.
Most manufacturers only honor a warranty when the unit came through an authorized dealer. We're authorized for Bussmann. A third-party marketplace seller usually isn't.
Gray-market stock, returns repackaged as new, and outright fakes move through marketplaces constantly. It all looks identical in the photo. It stops looking identical when it fails.
Ours is a phone number with a person behind it who has held this product. M–F, 6 AM – 5 PM Pacific. (866) 469-8556
Amazon, Home Depot, and Lowe's are built to pull every hardware dollar out of your town. When the local shop can't keep the lights on, the counter where somebody actually knew which part you needed goes with it. We're built the other way: real brands so you're never stuck on a marketplace, and a straight answer to buy it down the street when that's the better call. Support independent hardware — it doesn't restock itself.

Whether you're a contractor, property manager, facility team, or government buyer — one application unlocks pricing, terms, and service built for the way you actually buy.
Apply for a Pro Account Or call (866) 469-8556Every product comes directly from the trusted manufacturers you know — sourced directly through authorized manufacturer channels — the trusted brands your neighborhood hardware store carries.
When something's better bought down the street, we'll tell you — and point you to a local store that stocks it. We list independent retailers at no cost to most of them. We're not a marketplace, not a chain, not a faceless warehouse.
We come from the hardware world — the people answering your questions know the products, not just a script. Questions about fit, compatibility, or what a job actually calls for? You'll reach a real person, not a chatbot or a contracted call center.
The world's fast and convenient now, and it's only getting faster — same-day, next-hour, a screen where a face used to be. That's not going away, and we're not pretending it should. We live here too. We can move when you need us — most orders land in under two business days.
But the store on the corner probably has it on the shelf right now. And it was never only about speed. It's the person who knows the product and knows your name. It's what that store puts back into the town — the people it hires, the team it sponsors, the neighbor it shows up for. That's the part a warehouse can't ship.
These places have anchored their communities for generations. Keeping them around for the next two hundred and fifty years matters more than any single sale — ours included. So we'll be the convenient option when you need one, and we'll point you local whenever it makes sense. If it's better bought down the street, we'll say so.
If you're rooting for a handful of giant corporations to swallow every small store on Main Street — we'll be straight with you: we're not your shop. And that's alright. We were never trying to be everyone's.
We support local hardware stores.
We don't replace them.
