Bussmann CBB-30 – Frequently Asked Questions

1) Will a Bussmann CBB-30 circuit breaker work on a 12-volt vehicle system?
The CBB-30 is rated 24 V DC, so it is intended for 24-volt vehicle and mobile equipment circuits. A DC breaker rated at 24 V DC will interrupt reliably on a lower-voltage 12-volt circuit, but if your spec or drawing calls out a 12 V DC breaker specifically, order to that rating rather than substituting.
2) Is the Bussmann CBB-30 a direct replacement for an existing Type II breaker in my truck's power panel?
Yes, for panels already built around the Bussmann Type II footprint. The CBB-30 follows that Type II series footprint, so it drops into existing automotive circuit protection layouts using the same mounting configuration. Match the electrical side too: it is a 30 A, 24 V DC breaker, so confirm the circuit it is protecting is sized for 30 amps before swapping.
3) Is the CBB-30 a fuse or a resettable circuit breaker?
It is a circuit breaker, not a fuse. The CBB-30 is a Bussmann CBB series automotive circuit breaker providing 30 A overcurrent protection at 24 V DC, so it protects wiring and connected loads the same way a blade fuse would but as a breaker device rather than a one-time element.
4) What part number do I order for a 30 amp Bussmann automotive breaker?
The manufacturer part number is CBB-30, from the Eaton Bussmann CBB series. The amperage is carried in the suffix, so a CBB series number ending in -30 is the 30 amp version.
5) Can I use the CBB-30 on off-road or mobile equipment wiring rather than an on-highway vehicle?
Yes. The CBB series is built for automotive and mobile equipment circuits, including off-road equipment wiring, and the CBB-30 covers 24 V DC circuits protected at 30 amps. It is used in both OEM builds and aftermarket circuit protection where a Type II footprint is already in place.
