Blue Sea 7402 Single Pole Small Case 2" Flat Rocker Circuit Breaker - 10 Amp

The Blue Sea 7402 Single Pole Small Case 2" Flat Rocker Circuit Breaker in 10 Amp is a compact electrical protection device engineered for DC electrical systems in marine vessels, RVs, off-grid power installations, and vehicle-mounted equipment. This single-pole breaker combines reliable overload protection with a "trip free" design that prevents the switch from being forced into the ON position during a fault condition—a critical safety feature in systems where manual override could create dangerous situations.

The 10 Amp rating makes this breaker suitable for branch circuit protection in moderate-load applications, such as fresh water pumps, navigation systems, auxiliary lighting, or accessory power on tactical vehicles and expedition equipment. The 2-inch flat rocker actuator provides a positive, easy-to-operate switching mechanism with a color indicator that clearly shows the OFF position, allowing users to quickly verify circuit status even in low-light conditions. The small case design minimizes panel space while maintaining industrial reliability and meeting marine electrical standards.

Operators and system integrators rely on this breaker type for applications where redundant manual and automatic shutdown is essential. The trip-free architecture ensures that if fault current develops downstream—due to short circuits, arc faults, or equipment failure—the breaker will open regardless of whether someone is holding the handle in the ON position. This is standard practice in marine and remote-power installations where no external monitoring may be available. The 3 × 1 × 5 inch form factor fits standard DIN rail and panel-mount installations without requiring extensive rewiring or enclosure modification.

Blue Sea Systems is recognized in the marine, RV, and specialized electrical equipment market for producing UL-listed circuit protection products that function reliably in harsh salt-air, vibration, and temperature-extreme environments. The 7402 model carries the same quality standards and is a direct replacement or upgrade option for systems originally equipped with legacy breakers.
