Product Overview
Sealed Yellow In-Line Fuse Holder for Wet, Shaky Places, Complete with Fuse and Lugs
Condition
Unused NOS. The yellow elastomer body is clean and unmarked, and the molded lettering is still crisp: one boot half reads BUSS HFB with the word FUSE and a directional arrow, the other reads 30A 32V. The two crimp fuse-cap contacts, the two ring terminals, and the single fork terminal are all silver-colored metal, the contacts bright and the ring and fork terminals a duller matte finish, with no oxidation, no solder, and no wire remnants. The supplied glass fuse is clear, its element intact, with 3A printed on one end cap. Shipped loose and unassembled, as photographed.
Same or next business day shipping from our Idaho warehouse. Honest pricing, no nonsense.

Product Overview
This is an Eaton Bussmann HFB series in-line fuse holder: two molded yellow boots joined by a flexible tether that keeps the halves captive and folds into a loop when the holder is closed. It takes AGC style 1/4" x 1-1/4" (6.35 mm x 31.8 mm) fuses and accepts #16 to #12 AWG copper wire. The housing carries an IP67 rating for exposed and outdoor locations, MIL STD 810C vibration resistance, a +100 °C RTI temperature rating, and a brittle point below -60 °C, so it holds up where a panel-mount holder would not. The body is molded 30A 32V, and the kit ships with a Buss AGC 3A 250V fuse, two crimp fuse-cap contacts, and three wire lugs (two ring terminals and one fork terminal). Bright yellow is not decoration here: it is so a technician can find the fuse in a dark bilge or a black wiring loom on the first pass.

Frequently Asked Questions
What exactly comes in this listing?
One two-piece yellow HFB holder body with its flexible tether, two crimp fuse-cap contacts, three wire lugs (two ring terminals, one fork terminal), and one Buss AGC 3A 250V glass fuse. It ships loose and unassembled, as photographed.
The body says 30A 32V but the fuse is 3A 250V. Which one matters?
They describe two different things. 30A 32V is the marking molded into the holder housing, which is the holder's own limit. The 3A 250V is the fuse that happens to be supplied with it, and the fuse is what actually sets the trip point for your circuit. Fit whatever AGC fuse your circuit calls for, at or below the holder's marked rating. Full product specifications for this BUSSMAN Series product from Eaton.
What fuse size and wire gauge does it take?
AGC style 1/4" x 1-1/4" (6.35 mm x 31.8 mm) fuses, and #16 to #12 AWG copper wire. The two fuse-cap contacts crimp onto the wire and then seat into the boots.
Will it really stay sealed outdoors?
It is rated IP67, with MIL STD 810C vibration resistance and a -60 °C to +100 °C range, so it is built for exposed service. Sealing depends on a proper crimp and the boots being fully seated over the wire jacket, so take the extra minute on assembly.
Why buy one or two of these instead of a bulk pack somewhere else?
Because you probably need one fuse holder, not ten. We sell the exact quantity you need for the repair or the prototype in front of you. Shipping is $8 flat rate and free over $28, so a small order still costs less than a forced lot, and it leaves our Idaho warehouse the same or next business day.
Bussmann molded the word FUSE and a little arrow right into the boot, for whoever ends up hunting a dead circuit in the rain with a flashlight in their teeth. This one has never been opened for anyone else, and that job is yours now.
