Blue Sea 7454 UL-489 Circuit Breaker - 5A Flat Rocker

The Blue Sea 7454 UL-489 Circuit Breaker - 5A Flat Rocker is a precision electrical protection device engineered for military and maritime applications where federal compliance is non-negotiable. Designed to meet rigorous UL-489 specifications, this 5-ampere breaker serves Navy vessels, Army installations, Coast Guard platforms, and any vessel operating under CFR 46 regulations. In tactical and military environments, reliable circuit protection directly impacts mission readiness and crew safety—making proper breaker selection critical.

This circuit breaker features a flat rocker actuator design that delivers smooth, positive operation in demanding conditions where toggle switches may fail. The UL-489 rating ensures the breaker meets American and international safety standards for DC and AC electrical systems on vessels, protecting equipment and personnel from overload and short-circuit faults. At 5A capacity, it provides precise amperage control for sensitive avionics, communications systems, and auxiliary power circuits found aboard military vessels and tactical platforms. The compact 3 x 2 x 4 inch form factor and lightweight 0.25 lb construction enable integration into tight electrical panels without compromising panel real estate or system weight.

Naval engineers, ship electricians, and military logistics personnel rely on UL-489 certified breakers to ensure vessels remain in compliance during inspections and operational deployments. This breaker excels in marine environments where salt spray, vibration, and thermal cycling demand superior reliability. Installation integrates directly into DIN-rail or panel-mount systems using industry-standard fasteners, making retrofit and maintenance straightforward for trained technicians. Whether protecting radar systems, navigation equipment, or secondary power distribution on military vessels, the Blue Sea 7454 delivers the proven protection and regulatory compliance that defense and maritime operations demand.
