Blue Sea Systems Toggle Circuit Breaker — Double Pole 50A White
The BSS-7242 is a double-pole 50A toggle-style circuit breaker built for high-current marine DC applications where both conductors must be isolated simultaneously. At 50 amps, it handles the heavy loads — windlasses, thrusters, inverter feeds, and large DC motors — while the double-pole configuration ensures complete circuit isolation with a single toggle. White finish suits traditional and classic panel layouts.
Key Specifications

Parts Desk Insights
Best use case: The BSS-7242 is the top of the toggle breaker line for applications that need 50A of double-pole protection. It’s most commonly specified for windlass and thruster circuits on vessels with isolated ground systems, and for inverter feeds where both the positive and negative conductors need to be interrupted for safe servicing. The toggle format is well-suited to traditional panel builds where handle position communicates circuit status at a glance.
If 50A double-pole is more than your circuit requires, the BSS-7365 Double Pole 30A is the step down. If you only need to switch the positive conductor, the single-pole rocker breakers — BSS-7417 50A or BSS-7549 100A — are a simpler and more compact option.
