Bussmann CBC-10 – Frequently Asked Questions
1) What does Type I mean on a Bussmann CBC automotive circuit breaker?
Type I is the auto-reset configuration on the CBC series. The breaker trips on overcurrent and then resets itself once it cools, so the circuit comes back without anyone touching it. That is what you want on a circuit where nobody can get to the breaker easily, and it is what you do NOT want on a circuit where repeated cycling could be a hazard, such as a winch or a starter-adjacent feed. If you need it to stay open until someone clears the fault, a Type I breaker is the wrong choice.
2) What amperage ratings does the Bussmann CBC circuit breaker come in?
Nine ratings: 8A, 10A, 15A, 20A, 25A, 30A, 35A, 40A and 50A, ordered as CBC-8 through CBC-50. Size it to the wire, not the load. Everything else about the breaker (14VDC, Type I, #10-32 stud) is identical across the range, so you can spec one mounting pattern and terminal hardware for an entire panel and just vary the amp rating per circuit.
3) Should I use an auto-reset breaker like the CBC or just a blade fuse for an accessory circuit?
A blade fuse is a one-shot device: it blows and someone has to find a spare. The CBC is a Type I breaker, so it resets on its own once it cools, which is the better call on circuits that see nuisance overloads or that sit behind a dash or under a body panel where swapping a fuse means pulling trim. The tradeoff is that a repeating fault will keep re-energizing the circuit instead of staying dead, so on anything where that matters, a fuse or a manual-reset breaker is the safer pick.
4) Is the Bussmann CBC breaker rated for AC or for household 120V wiring?
No. The CBC is a DC device rated 14VDC, built for vehicle and mobile electrical systems. It has no AC rating and must not be used on 120V branch circuits or any line-voltage work. For building wiring you need a UL 489 branch circuit breaker, which is a different product entirely.
5) What part numbers do I order for a 30 amp and a 50 amp Bussmann CBC breaker?
CBC-30 for the 30 amp and CBC-50 for the 50 amp. The numbering runs straight off the amperage across the whole series, so CBC-8, CBC-10, CBC-15, CBC-20, CBC-25, CBC-30, CBC-35, CBC-40 and CBC-50 are the complete set of Eaton Bussmann part numbers.
