Blue Sea 7543 C-Series Flat Rocker Circuit Breaker - Single Pole - 20A

The Blue Sea 7543 C-Series Flat Rocker Circuit Breaker is a single-pole 20-amp marine electrical protection device designed for reliable DC power distribution on recreational vessels. This circuit breaker is essential for preventing electrical failures that can occur when you're far from help, safeguarding engines, navigation systems, and onboard electronics.

Featuring a compact flat rocker design, it installs easily into tight panel spaces typical of center consoles, cabin cruisers, and offshore fishing rigs. The 7543 provides automatic overcurrent protection, making it ideal for branch circuits that power individual systems like bilge pumps, trim tabs, or fish finders. Its tactile and responsive switch mechanism allows for instant manual override in emergencies.

This circuit breaker is particularly beneficial for offshore anglers and cruising captains, as it integrates seamlessly into existing panels or new custom installations without requiring major rewiring. The 20-amp rating is compatible with standard marine-grade 10-gauge wire, ensuring safety margins for typical 12- or 24-volt DC systems.
