Bussmann F15A250V20AS – Frequently Asked Questions

1) What amp ratings can I get the Bussmann F09A250V fast-acting fuse in?
The F09A250V series covers 22 amp ratings from 1A up to 200A: 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 15, 20, 25, 30, 35, 40, 45, 50, 60, 100, 110 and 200 amps. Each amp rating is a separate orderable part, so specify the amperage that matches the circuit load you are protecting.
2) Is the Bussmann F09A250V rated for a 250 volt circuit?
Yes, it carries a 250V rating and is intended for instrument, power and telephone circuits at that voltage. A fuse voltage rating is a maximum, so it can be applied on circuits at or below 250V, but never above it.
3) Does this Bussmann fuse have a blown-fuse indicator?
No. The F09A250V is non-indicating, standard construction, so there is no pop-up pin or visual flag when it opens. Troubleshooting means pulling the fuse and checking continuity, or using a holder or block with its own indication. If your maintenance crew depends on seeing an open fuse at a glance, order an indicating type instead.
4) What does fast-acting mean on this fuse, and when should I use a time-delay fuse instead?
Fast-acting means the element opens quickly on an overcurrent rather than riding through a temporary surge. That is what you want ahead of instruments, telephone equipment and sensitive electronics, where the fuse has to clear before the load is damaged. If you are feeding a motor, transformer or anything with a heavy inrush at startup, a fast-acting fuse will nuisance-open and you should be specifying a time-delay type in that amp rating instead.
5) Is the Bussmann F09A250V a military-qualified fuse?
Yes, it is built to military qualification standards, which is the reason it gets specified on defense, aerospace ground support and other high-reliability jobs where a commercial-grade fuse will not satisfy the submittal. If your drawing calls out a military-qualified fuse at 250V, this series answers it.
6) I need to order a specific amperage, what part number do I give my supplier?
The part number changes with the amp rating rather than staying constant across the series. A 2A is F09A250V2AS, 8A is F09A250V8A, 15A is F15A250V15A, 30A is F61C500V30A, 60A is F62C500V60A and 200A is F64C500V200AS. Call out the amperage you need and match it to the exact manufacturer part number so you do not get a neighboring rating.
7) Can I use the Bussmann F09A250V for telephone and signal circuit protection?
That is one of its listed applications. The series is built for instrument, power and telephone circuit protection, and the fast-acting element suits control and signal work where the connected equipment cannot tolerate a slow clear. Low amp ratings starting at 1A are available for those light circuits.
8) How is the Bussmann F09A250V packaged for MRO stocking?
Standard packaging, which suits pulling individual amp ratings for panel stock rather than buying a bulk reel or kit. Facilities standardizing a spares crib usually stock the common ratings (5A, 10A, 15A, 20A, 30A) and add the higher ones only where the equipment calls for them.
