Blue Sea Systems builds the breakers that protect marine wiring. Size the breaker to the wire, pick push-button or switchable, and keep it ignition protected where it counts. A circuit breaker protects the wire, not just the gear on the end of it, and Blue Sea Systems builds the marine breakers that do that job reliably. This collection covers push-button reset breakers, toggle and switchable breakers, and panel-mount units across the full amp range. Choosing right comes down to sizing the breaker to the wire, picking the style that fits the install, and meeting the safety rules for your boat. Size the breaker to the wire, not the load This is the rule people get backward. A breaker exists to...

Blue Sea Systems builds the breakers that protect marine wiring. Size the breaker to the wire, pick push-button or switchable, and keep it ignition protected where it counts.
A circuit breaker protects the wire, not just the gear on the end of it, and Blue Sea Systems builds the marine breakers that do that job reliably. This collection covers push-button reset breakers, toggle and switchable breakers, and panel-mount units across the full amp range. Choosing right comes down to sizing the breaker to the wire, picking the style that fits the install, and meeting the safety rules for your boat.
This is the rule people get backward. A breaker exists to stop the wire from overheating before it can start a fire, so you size it to the ampacity of the wire gauge it protects, not to the appliance draw. Pick the wire for the load and length first, then choose a breaker rated at or below what that wire can safely carry. Oversizing the breaker defeats the whole point.
Push-button reset-only breakers are compact and great for protecting a single circuit behind a panel. Switchable breakers, like the A-Series and toggle styles, double as an on-off switch and a breaker in one, which cleans up a panel by combining functions. Use switchable breakers where you want to kill the circuit by hand and protect it in the same spot.
Most 12-volt DC circuits use a single-pole breaker on the positive. AC circuits and some applications need double-pole breakers that open both conductors. Confirm whether you are protecting DC or AC and match the breaker rating and pole count to the system, because they are not interchangeable.
In a gasoline engine compartment or any space where fuel vapors can collect, the breaker must be ignition protected so it cannot spark a fire. Blue Sea marks ignition-protected parts clearly. Do not put a non-rated breaker in a gas engine space.
Match the breaker to your setup. Panel breakers integrate into a Blue Sea panel for a clean helm, while surface-mount and in-line breakers protect a single run near the source. Plan where the breaker lives so it is accessible to reset.
Not sure which breaker your circuit needs? Tell our techs the wire gauge, the load, and whether it is AC or DC, and we will match the amp rating, style, and pole count so the wiring is protected right.
Size the breaker to the wire it protects, not the appliance draw. Pick the wire gauge for the load and run length first, then choose a breaker rated at or below what that wire can safely carry. The breaker protects the wire from overheating.
Push-button reset-only breakers are compact for protecting a single circuit. Switchable breakers, like the A-Series, act as both an on-off switch and a breaker, which cleans up a panel by combining the two functions.
Most 12-volt DC circuits use a single-pole breaker on the positive. AC circuits and some setups need double-pole breakers that open both conductors. Match the pole count and rating to whether the system is AC or DC.
An ignition-protected breaker cannot spark a fire in a space where fuel vapors can collect, such as a gasoline engine compartment. Blue Sea marks these parts clearly, and you should never use a non-rated breaker in a gas engine space.
No. Oversizing the breaker removes protection from the wire and creates a fire risk. If a correctly sized breaker keeps tripping, the circuit is overloaded or faulted and needs to be fixed, not masked with a larger breaker.
