Bussmann 24B-4 – Frequently Asked Questions

1) Will the Bussmann 24B-4 fit a standard Type 24 telecom fuse holder?
Yes. The 24B-4 is an Eaton Bussmann series Type 24 flat fuse, built to drop into Type 24 telecom fuse holders and panels. The body measures 1.46 in in length and .375 in in height, which is the low-profile flat form factor those holders take. If your panel uses a cartridge or GMT-style holder rather than a Type 24 flat clip, this is not the part.
2) What amperage and voltage is the Bussmann 24B-4 rated for?
4 A at 60 V DC. That rating is for low-voltage DC telecom circuits, central office and network equipment, not AC branch circuits. Replace like for like: a 4A Type 24 position takes a 4A fuse, and the yellow body on the 24B-4 is the color code for that amperage.
3) Does the 24B-4 telecom fuse show you when it has blown?
No. The 24B-4 is a non-indicating fuse, so there is no pop-up pin or flag to tell you it has opened. On a distribution frame you will need a meter or an alarm circuit on the panel to find the open fuse. If your maintenance routine relies on walking the frame and spotting a tripped indicator, you want an indicating Type 24 fuse in the same 4A rating instead.
4) Can I use a Bussmann 24B-4 on a 120V AC circuit or a 125Vdc plant?
No. The 24B-4 is rated 60 V DC only. It is a telecommunication fuse for low-voltage DC circuits, central office switching gear, signal line holders and rack-mounted telecom systems. Anything above 60 Vdc, or any AC branch circuit, needs a different fuse class entirely.
5) How do I identify the right amperage Type 24 fuse on a crowded telecom frame?
Go by the color code. Type 24 flat fuses are color coded by amperage and the 24B-4 is yellow at 4A, so a tech can confirm the rating at a glance without pulling the fuse and reading the body. That matters on a cross-connect panel where dozens of positions sit side by side.
6) How is the Bussmann 24B-4 fuse packaged and what does one weigh for stocking?
It ships in standard packaging, with a listed product weight of .2 lb, which suits bin stocking for MRO crews and distributors carrying spares for telecom frames.
