Bussmann Eaton CBF Series Type II Automotive Circuit Breaker

The Bussmann Eaton CBF Series Type II Automotive Circuit Breaker is a resettable overcurrent protection device built for automotive electrical circuits, with the CBF family available in 6A, 10A, 25A, 30A, 35A, and 40A ratings so installers can match the breaker to the specific circuit load. As a Type II automotive circuit breaker, the CBF series is designed to open and interrupt current when an overload occurs, helping protect vehicle wiring, accessories, and connected components from damage. Whether the application calls for a lower-amperage accessory circuit or a higher-draw automotive load, the CBF series offers a rating across its 6A-40A range to fit the job, all under the trusted Eaton Bussmann name.

Key Features

  • Amp Rating Range: The Bussmann CBF series is offered in 6A, 10A, 25A, 30A, 35A, and 40A ratings, giving installers a single trusted series to cover a broad range of automotive circuit protection needs.
  • Type II Circuit Breaker: This Type II configuration is built for automotive circuit protection applications that call for a resettable overcurrent device rather than a one-time fuse.
  • Eaton Bussmann CBF Series: Part of the Eaton Bussmann CBF platform, engineered for dependable, repeatable overcurrent protection performance in automotive electrical systems.
  • Automotive-Specific Application: Purpose-built for automotive use, the CBF series is intended for vehicle wiring and accessory circuits rather than general industrial or residential panels.
  • Resettable Protection: As a circuit breaker rather than a fuse, the CBF series can be reset after tripping, reducing the need to carry and swap replacement fuses in the field.

Bussmann CBF-10 – Frequently Asked Questions

1) What amp ratings does the Bussmann CBF Series automotive circuit breaker come in?
The CBF Series is built in six ratings: 6A, 10A, 25A, 30A, 35A, and 40A, ordered as CBF-6, CBF-10, CBF-25, CBF-30, CBF-35, and CBF-40. Size the breaker to the circuit it protects, not to the accessory's peak draw alone. There is no 15A or 20A in the CBF line, so a circuit that calls for one of those needs a different series.
2) What does Type II mean on an automotive circuit breaker, and how is it different from Type I?
Type II is the modified-reset style: the CBF breaker opens on an overload and stays open while the fault is present, rather than cycling open and closed on its own the way a Type I auto-reset breaker does. That matters for what you put it on. An auto-reset Type I will keep re-energizing a shorted accessory circuit over and over; a Type II holds the circuit open until the fault clears, then resets. For a winch, light bar, or any accessory where you want the circuit to stay dead until someone looks at it, Type II is the configuration you want.
3) Can I use a Bussmann CBF breaker instead of a blade fuse so I stop replacing fuses?
That is the point of the CBF. It is a resettable overcurrent device rather than a one-time fuse, so a nuisance trip on a fleet vehicle gets reset instead of requiring a spare fuse and a trip back to the truck. Match the CBF amp rating to the fuse rating you are replacing, and confirm the circuit was actually protected at 6A, 10A, 25A, 30A, 35A, or 40A, since those are the only ratings the CBF family covers.
4) Is the Bussmann CBF circuit breaker suitable for a house panel or an industrial control panel?
No. The CBF Series is an automotive circuit breaker, intended for vehicle wiring and accessory circuits, not for residential load centers or general industrial panels. For a building panel you need a breaker listed for that panel and that service. Use the CBF on 12V and 24V vehicle circuits, fleet and mobile equipment wiring, and OEM or aftermarket accessory circuits.
5) What amp rating should I pick for an auxiliary light or accessory circuit on a fleet vehicle?
Pick by the wire and the load, not by the breaker you have on the shelf. Low-draw accessory circuits (small lighting, gauges, switched signals) land at the 6A or 10A end of the CBF range. Higher-draw automotive loads such as heated seats, compressors, and multi-lamp light bars go to 25A, 30A, 35A, or 40A. The CBF tops out at 40A, so anything drawing above that needs a different protection device entirely.
6) Do all six amp ratings of the Bussmann CBF breaker use the same part number format?
They do. The part number is CBF plus the amperage, so CBF-6, CBF-10, CBF-25, CBF-30, CBF-35, and CBF-40. When you are spec'ing a fleet standard or writing a stocking list, that makes the ordering straightforward: one series, one prefix, and the number after the dash is the rating.
7) How much does a Bussmann CBF automotive circuit breaker weigh?
A CBF breaker weighs .34 lb. That is light enough to mount on a distribution bracket or an accessory panel without additional bracing, which is the usual concern when a breaker gets added to an existing upfit rather than an OEM box.
