Blue Sea 7311 COTS Military Grade A-Series 10 Amp

The Blue Sea 7311 COTS Military Grade A-Series 10 Amp circuit breaker is a mission-critical electrical protection device engineered for demanding military, law enforcement, and tactical vehicle applications. Designed to COTS (Commercial Off-The-Shelf) military standards, this compact breaker provides dependable overcurrent protection in environments where electrical system failure is not an option. Whether protecting sensitive avionics, communications equipment, or power distribution in tactical platforms, the 7311 delivers the reliability demanded by professional operators who depend on their gear under extreme conditions.

The A-Series 10 Amp rating is optimized for low-to-moderate current draw circuits, making it ideal for protecting individual systems without nuisance tripping during normal operational loads. Blue Sea Systems' breaker employs a thermally-compensated, trip-free mechanism that isolates faults instantly while preventing manual override—a critical safety feature in military applications where unintended reclosure could damage equipment or compromise personnel safety. The compact form factor (3 x 2 x 3 inches) and minimal weight (0.1 lbs) enable seamless integration into space-constrained tactical platforms, fire control systems, and modular command centers without adding measurable logistical burden.

Field operators, maintenance technicians, and system integrators working with military-spec electrical distribution systems will recognize the 7311 as a drop-in replacement for standard A-Series slots in Blue Sea panel assemblies and compatible switchboards. The 10 Amp capacity suits protection of discrete avionics feeds, LED arrays, low-power RF modules, and sensor circuits typical in modern tactical vehicles and forward-deployed command posts. Installation requires only clip-mounting into compatible bus bars—no special tools or reconfiguration necessary, allowing rapid field repairs and modular system reconfiguration during high-tempo operations.
