Bussmann BBS-1 Midget Fuse, Fast-Acting, 1A, 600V, Ferrule End

The Bussmann BBS-1 is a fast-acting Midget fuse from the Eaton Bussmann series BBS product line, engineered to deliver dependable overcurrent protection in a compact, small-dimension form factor. Rated for 1A at 600V, this fuse offers a 10 kAIC interrupting rating at 600 Vac, making it well suited for protecting sensitive control circuits and equipment where a fast response to fault conditions is critical. The BBS-1 features a ferrule end x ferrule end termination style, allowing it to install directly into standard Midget fuse holders, blocks, and disconnect switches without additional adapters. Nickel-plated brass endcaps provide corrosion resistance and a secure, low-resistance electrical connection at each ferrule contact point. As a non-indicating, standard fast-acting fuse, the BBS-1 is built for straightforward, code-compliant overcurrent protection in electrical panels and control systems that call for a compact 600V fuse.

Key Features

  • Amperage Rating: Rated 1A, sized for precise overcurrent protection of low-current control and instrument circuits.
  • Voltage Rating: Rated 600V with a 10 kAIC interrupting rating at 600 Vac, providing dependable fault-clearing capability.
  • Fast-Acting Operation: The fast-acting fuse element responds quickly to overcurrent conditions, helping protect connected equipment from damage.
  • Ferrule End Termination: Ferrule end x ferrule end configuration allows direct installation into standard Midget fuse blocks, holders, and fused disconnects.
  • Nickel-Plated Brass Endcaps: Corrosion-resistant nickel-plated brass endcaps maintain reliable, low-resistance contact at each termination point.
  • Non-Indicating Design: A standard, non-indicating body keeps the design simple and cost-effective for general-purpose fusing applications.
  • Compact Midget Fuse Body: The small-dimension Midget fuse footprint saves panel space compared to larger fuse classes while maintaining rated performance.
  • Series: Part of the Eaton Bussmann series BBS line of 600V small-dimension fuses.

Bussmann BBS-1 – Frequently Asked Questions

1) Will a Bussmann BBS-1 fit a standard midget fuse holder or fuse block?
Yes. The BBS-1 is a midget-class fuse with ferrule end x ferrule end termination, so it drops straight into standard midget fuse holders, blocks, and fused disconnect switches with no adapter. Midget bodies are the 13/32 x 1-1/2 inch small-dimension format, so if your holder is marked for midget fuses the BBS-1 seats in it.
2) Can I use a 600V fuse like the BBS-1 on a 240V or 480V control circuit?
Yes. The BBS-1 is rated 600V, and a fuse voltage rating is a maximum, so it can be applied at any system voltage at or below that. Its interrupting rating is 10 kAIC at 600 Vac. What you cannot do is go the other way and put a 250V midget fuse into a 600V circuit.
3) Is the BBS-1 fast-acting or time-delay, and which do I want for a control transformer?
The BBS-1 is a fast-acting element, so it clears quickly on a fault with no intentional delay. That suits instrument, relay, and low-current control circuits where you want the fuse to open before the connected device is damaged. For loads with an inrush surge, such as a control power transformer primary or a motor circuit, a fast-acting 1A fuse will likely open on energization, and you want a time-delay midget fuse instead.
4) Is the BBS-1 a class CC fuse, and will it fit a rejection-style class CC holder?
The BBS-1 is a ferrule-end midget fuse, not a rejection-style fuse. Class CC fuses have a grooved rejection feature on one endcap that only a CC holder accepts, so a plain ferrule midget like the BBS-1 will not latch into a CC rejection clip. Use it in a standard midget holder, block, or fused disconnect. If your panel is built on class CC rejection bases, order a class CC fuse instead.
5) Does the BBS-1 have a blown-fuse indicator?
No. The BBS-1 is a non-indicating fuse, so there is no pop-up pin or visual flag to show it has opened. You check it with a meter or by continuity. If you need at-a-glance identification in a panel, specify an indicating midget fuse or a holder with a blown-fuse indicator.
6) What is the exact part number and amp rating I should order for a 1 amp 600V midget fuse from Bussmann?
The part number is BBS-1, from the Eaton Bussmann BBS series of 600V small-dimension fuses. It is rated 1A at 600V. The amp rating is the last part of the number, so other ratings in the same family follow the same BBS pattern. Order by the BBS-1 marking stamped on the endcap to be certain you are matching what is already in the holder.
7) Are the endcaps on the BBS-1 suitable for a humid or washdown-adjacent panel?
The endcaps are nickel-plated brass, which resists corrosion and keeps a low-resistance contact at each ferrule clip. That helps in damp or chemically active panel environments where plain brass or copper caps can oxidize and cause nuisance heating at the clip. The fuse body itself is not a sealed enclosure, so it still belongs inside a rated panel or holder.
