Bussmann W-10 Fast-Acting Plug Fuse, 10A/125V, Edison Base
The Bussmann W-10 is a Eaton Bussmann series W plug fuse engineered for fast-acting overcurrent protection in Edison-base fuse panels. Rated 10 A at 125 Vac, this plug fuse delivers a 10 kAIC (RMS Symmetrical) interrupt rating and a 10 kA short circuit rating, giving installers dependable protection for branch circuits still equipped with Edison-base fuse holders. Constructed with a durable plastic body and a brass thread, the W-10 is built for reliable, code-compliant service in residential and light commercial applications.
Key Features
- Amperage Rating: 10 A fast-acting response for quick overcurrent interruption.
- Voltage Rating: 125 Vac rated for standard branch-circuit fuse panels.
- Interrupt Rating: 10 kAIC (RMS Symmetrical) interrupt rating for safe fault clearing.
- Short Circuit Rating: 10 kA short circuit rating supports demanding overcurrent conditions.
- Durable Construction: Plastic body resists damage and supports long service life in fuse panel applications.
- Brass Thread: Brass threaded base provides a secure, corrosion-resistant connection in the fuse holder.
- Edison Base: Standard Edison base fits legacy plug fuse panels for straightforward replacement.

Bussmann W-10 – Frequently Asked Questions
1) Will the Bussmann W-10 plug fuse screw into my old Edison base fuse box?
Yes. The W-10 uses a standard Edison base with a brass thread, so it threads into the same screw-in fuse holders found in legacy residential and light commercial fuse panels. Edison base is the common household plug fuse thread (the same thread as a light bulb socket), so no adapter is needed for a straight replacement.
2) Is a 10A fuse the right size for my circuit, or do I need 15A?
The W-10 is rated 10 A at 125 Vac, so it protects a branch circuit whose conductors and load are sized for 10 amps or less. If the circuit is a standard 15 amp branch on 14 AWG wire, a 10 amp fuse will nuisance-blow under normal load, and you want the 15 amp version of the Series W instead. Never fit a larger fuse than the circuit conductor allows.
3) What is the difference between a fast-acting plug fuse like the W-10 and a time-delay type?
Fast-acting is the key distinction. The W-10 opens quickly on overcurrent, which suits general purpose lighting and receptacle branch circuits with no inrush. Circuits feeding motor loads, compressors, or anything with a hard start draw several times running current for a moment, and a fast-acting fuse will clear on that startup surge. For those, a time-delay plug fuse (Bussmann T series) is the right choice.
4) What interrupting rating does the Bussmann W-10 have?
10 kAIC (RMS symmetrical), with a 10 kA short circuit rating. That matters when a panel is fed from a service with meaningful available fault current: the fuse has to clear the fault without rupturing. If your available fault current at the panel exceeds 10 kA, this fuse is not adequate for the location.
5) What is the exact part number to order for the 10 amp Bussmann Series W plug fuse?
Manufacturer part number W-10, from the Eaton Bussmann Series W line. The number carries the amperage: W-10 is the 10 amp version, and other amperages in the series follow the same W- prefix.
6) How many fuses come in a pack of the Bussmann W-10?
100 fuses per pack. That quantity suits a property maintenance shop or MRO crib keeping spares on hand for buildings still running Edison-base panels, where blown plug fuses are a recurring service call rather than a one-off.
7) What is the body of the W-10 plug fuse made of?
A plastic body with a brass threaded base. The brass thread resists corrosion in the fuse holder and keeps a solid contact, which matters in older panels where loose or oxidized contacts cause heating at the fuseholder rather than at the element.
