Blue Sea 7429 Single Pole Small Case 2" Slot Reset Rocker Circuit Breaker - 20 Amp

The Blue Sea 7429 Single Pole Small Case 2" Slot Reset Rocker Circuit Breaker – 20 Amp is a compact, marine-grade electrical protection component designed for tactical vehicles, mobile command centers, and ruggedized equipment installations where space and reliability are non-negotiable. Built to withstand the demands of law enforcement, military, and emergency response applications, this breaker integrates seamlessly into power distribution systems where conventional panel-mount options are impractical. The 20-amp rating makes it ideal for protecting moderate-draw circuits in auxiliary power systems, inverters, and auxiliary lighting arrays commonly found in tactical support vehicles.

This single-pole breaker features a color-coded rocker actuator that clearly indicates the OFF position, providing visual confirmation of circuit status at a glance—critical during equipment checks or emergency shutdown procedures. The trip-free design ensures the breaker cannot be manually held in the ON position if an overcurrent condition develops, protecting downstream equipment and preventing operator override during fault conditions. The compact 2" slot mounting format and small case profile allow installation in tight spaces without requiring full-depth panel cavity, while the reset mechanism enables field-level circuit restoration without component replacement, minimizing downtime in remote operational environments.

Tactical operators and vehicle integrators benefit most from this breaker's marine-grade construction and proven reliability in high-vibration, temperature-extreme, and moisture-exposed platforms. Installation is straightforward in any 2" slot distribution panel, making it compatible with existing Blue Sea Systems mounting infrastructure and aftermarket tactical electrical systems. At 0.15 lbs, it adds minimal weight to vehicle builds while delivering the electrical protection integrity required for life-critical communications, medical equipment, and weapons systems that depend on consistent, uninterrupted power delivery in the field.
