Blue Sea 7353 C-Series Toggle Single Pole - 20A

The Blue Sea 7353 C-Series Toggle Single Pole 20A switch delivers integrated overcurrent protection and switching capability in a compact single-pole design, purpose-built for marine electrical systems. This combination breaker-switch eliminates the need for separate circuit protection and manual switching devices, consolidating two critical functions into one space-efficient component that meets the demands of modern boat wiring.

Rated at 20 amperes, the Blue Sea 7353 handles high-draw marine loads such as inverters, bow thrusters, and electric windlasses without requiring additional panel space. The toggle actuator provides positive manual control—critical for emergency shutdowns and routine system management. The "trip-free" design is a key safety feature: if an overcurrent condition occurs, the switch cannot be held in the closed position, ensuring the circuit opens and protects equipment from damage, even if the operator attempts to override the protection.

Boaters installing auxiliary power systems, upgrading electrical panels, or retrofitting higher-capacity loads benefit from this switch's reliability. The white toggle lever integrates cleanly into standard marine panels. Serious cruising sailors and offshore fishermen who depend on redundant systems and clean electrical architecture choose Blue Sea Systems components for their proven track record in saltwater and high-vibration environments. Compact dimensions and straightforward installation make the 7353 suitable for both new builds and retrofits.

Blue Sea Systems is the industry standard for marine electrical protection. The 7353 C-Series continues that reputation by delivering dual-function protection in the footprint of a simple toggle switch, reducing weight and complexity on vessels where every inch of panel real estate matters.
