Blue Sea Systems Surface Mount Circuit Breaker — 200A
The BSS-7149 is a 200A surface mount DC circuit breaker designed for high-current marine applications where a main disconnect or heavy-load protection is required. It mounts directly to a bulkhead, battery box, or engine room surface — no panel cutout needed — and provides automatic overcurrent protection with a manual reset. At 200 amps, this is a main-bus-level device: battery bank protection, windlass or thruster mains, and large inverter feeds.

Parts Desk Insights
Best use case: The BSS-7149 is a main-bus breaker — it belongs at the top of the circuit, between the battery bank and the distribution panel or high-current load. At 200A it’s sized for large windlass installations, high-capacity inverters, and battery bank protection on cruising and commercial vessels. The surface-mount format makes it easy to install in tight engine rooms or battery compartments where a traditional panel-mount breaker won’t fit.
If 200A is more than your circuit requires, the BSS-7142 80A surface mount breaker or the 187 Series 150A are the next steps down. For panel-mount options at high current, see the BSS-7549 100A rocker breaker.
