Blue Sea 7316 COTS Military Grade A-Series 40 Amp

The Blue Sea 7316 COTS Military Grade A-Series 40 Amp circuit breaker is engineered for demanding electrical systems where military-specification reliability is non-negotiable. Designed to meet CFR 46 standards, this heavy-duty breaker serves law enforcement, military, emergency response, and marine platforms where mission-critical power distribution cannot fail. Its robust construction and precise amperage rating make it the go-to choice for vehicle electrical upgrades, command vehicle installations, and tactical equipment power management.

Built with a metal toggle actuator and dual-pole (2-pole) configuration, the 7316 delivers reliable circuit protection across both positive and return legs of a 40-amp circuit. The breaker handles maximum voltage ratings of 277V AC and 65V DC, giving operators flexibility across diverse power architectures—from vehicle electrical systems to portable generator arrays. The metal toggle design provides positive tactile feedback and durability under vibration and thermal cycling common in tactical vehicles and field operations, while the COTS (Commercial Off-The-Shelf) military-grade construction ensures parts commonality and field serviceability.

This breaker is ideal for professionals upgrading or maintaining power systems in armored personnel carriers, command posts, communications platforms, and certified marine vessels operating under federal maritime regulations. Installation requires standard DIN-rail or panel mounting in accordance with electrical code and vehicle-specific wiring diagrams. The 1-pound weight keeps vehicle electrical load minimal while delivering the surge protection and load-shedding capability that keeps critical systems online when seconds matter. Operators and technicians familiar with standard circuit protection will recognize the proven A-Series design and appreciate its straightforward integration into existing 40-amp circuits.
