Blue Sea Systems Rocker Circuit Breaker — Single Pole 100A Black
The BSS-7549 is a single-pole 100A rocker-style DC circuit breaker designed for high-current marine applications. It combines the function of a switch and a circuit breaker in one unit — you can manually open and close the circuit like a switch, and it will automatically trip if the current exceeds its rated capacity. At 100 amps, this is built for the heavy loads: windlasses, thrusters, inverters, and large DC motors.

Parts Desk Insights
Best use case: The BSS-7549 is the right choice when you need 100A of circuit protection with the convenience of a manual on/off rocker — no separate switch required. It’s most commonly used on windlass and thruster circuits where you want to be able to isolate the load quickly at the breaker itself. The rocker format makes it easy to mount in a panel or on a bulkhead and operate with one hand.
If your installation requires a surface-mount breaker rather than a panel-mount rocker, the Blue Sea Systems 187 Series 100A Surface Mount Breaker is the equivalent in that format. For lower-current circuits, see the 30A BSS-7414 or 50A BSS-7417 rocker breakers.
