Bussmann CBBF-100 – Frequently Asked Questions

1) What amp ratings does the Bussmann CBBF marine battery fuse come in?
The CBBF series runs 30A through 300A in 13 steps: 30, 40, 60, 75, 80, 100, 125, 150, 175, 200, 225, 250 and 300 amps. Part numbers follow the rating directly, so a 150 amp fuse is CBBF-150 and a 300 amp is CBBF-300. That spread covers everything from a small accessory feed off a house bank up to a large DC distribution takeoff.
2) Is this fuse actually rated for use on a boat, or just a standard battery fuse?
Marine rated construction is the point of the CBBF. Bussmann built the series specifically for battery circuit protection in wet, corrosive onboard environments, which is why it is specified for boat electrical systems, shipboard panels and marine repower wiring rather than being a general-purpose automotive part.
3) Can I use a CBBF fuse on the main positive cable off my house battery bank?
That is exactly what it is built for. The CBBF is a purpose-built battery fuse for protecting DC battery circuits against overcurrent and short circuits, and it is applied at battery banks and DC power distribution takeoffs. Size the fuse to the circuit you are protecting, not the bank capacity, and pick from the 30A to 300A range.
4) What is the part number for a 100 amp Bussmann marine battery fuse?
CBBF-100 is the 100 amp version. The neighbouring sizes are CBBF-80 and CBBF-125, so if the 100A leaves no headroom for your inrush you have a one-step move in either direction without leaving the series.
5) Is the CBBF a resettable breaker or a one-time fuse?
It is a fuse, not a breaker. Once a CBBF clears an overcurrent or short circuit event it is spent and gets replaced with the same rating. If you need a device you can reset from the helm after a nuisance trip, a marine-rated DC circuit breaker is the different product to look at.
6) Can I standardize my fleet's DC panels on one fuse series?
Yes, and that is a practical reason to spec CBBF across a fleet or a yard. One series, one mounting style, 13 ratings from 30A to 300A covering nearly any battery bank or DC distribution branch, so your spares kit is a single line of part numbers stepping CBBF-30 through CBBF-300.
