A DC-rated circuit breaker does the same job as a fuse — protecting a section of wiring from overcurrent — but it can be reset with a flip of a switch instead of needing a replacement part on hand. That makes it a convenient choice for spots in your system where a nuisance trip is more likely, since you’re not stuck without a spare fuse if it trips at an inconvenient time.
These come in a range of amperages to match different points in your system, from smaller breakers protecting individual circuits to larger ones sized for your main battery connection. Match the breaker’s rating to the wire gauge and load it’s protecting — an oversized breaker won’t protect the wiring the way it’s supposed to.
If you’re deciding between fuses and breakers for this part of your system, our complete safety guide compares both.
