Bussmann CBS-10 – Frequently Asked Questions

1) What amp ratings does the Bussmann CBS automotive circuit breaker come in?
Seven ratings cover the CBS line: 6A, 10A, 15A, 20A, 25A, 30A and 40A. The part number follows the rating directly, so a 20 amp breaker is CBS-20 and a 40 amp is CBS-40. Match the rating to the wire and load on the circuit you are protecting, not to the largest breaker that fits.
2) Which CBS amp rating do I need for my circuit?
Size the breaker to the conductor and the load, not the other way around. Low-draw accessory circuits (interior lighting, small controllers) sit at the 6A and 10A end; general accessory and pump circuits typically land at 15A to 25A; higher-draw items like heaters, inverter feeds and auxiliary lighting use 30A or 40A. The CBS range stops at 40A, so anything drawing above that needs a different protection device.
3) Should I use a CBS circuit breaker or a blade fuse for a vehicle accessory circuit?
A fuse opens once and has to be replaced; the CBS is a circuit breaker, so it interrupts an overload and can be reset rather than swapped out. That matters on circuits that see occasional inrush or nuisance trips, like winches, lighting bars and power accessories, or on hardware buried where getting at a blown fuse is a nuisance. For a circuit that should never come back on by itself after a fault, a fuse is still the simpler choice.
4) Can I use a Bussmann CBS breaker on a boat or off-road machine, or is it cars only?
The CBS series is built for automotive and mobile electrical systems generally, and its stated applications include marine and off-road vehicle wiring, mobile equipment circuits, and both aftermarket and OEM automotive installs. Anything running on a vehicle-type DC system with wiring you need to protect from overload is within what the series is intended for.
5) Is the Bussmann CBS breaker suitable for household or panel wiring?
No. The CBS is an automotive circuit breaker, intended for vehicle and mobile equipment electrical systems, not for branch circuits in a building panel. Residential and commercial AC branch protection needs a breaker listed for the panel it goes in. Use the CBS for vehicle harnesses, accessory circuits and mobile equipment wiring.
6) Can I standardize a whole fleet on the Bussmann CBS series?
Yes, and that is a common reason to spec it. One series, seven ratings from 6A to 40A, and part numbers that read straight off the rating (CBS-6 through CBS-40) means a stockroom carries one family instead of several and a technician picks by amperage alone. For a maintenance operation running mixed vehicles or mobile equipment, that cuts the number of line items you have to keep on the shelf.
