Blue Sea 7312 COTS Military Grade A-Series 15 Amp

The Blue Sea 7312 COTS Military Grade A-Series 15 Amp circuit breaker is engineered for mission-critical electrical protection in demanding environments where military specifications under CFR 46 are required. This magnetic hydraulic trip-free breaker delivers reliable overload and short-circuit protection for 15-amp DC and AC circuits, making it the standard choice for marine vessels, tactical platforms, and systems where component failure is not an option.

The 7312's specifications reflect its military-grade design. Its magnetic hydraulic mechanism provides smooth trip response without nuisance breakers, while the trip-free actuator ensures the breaker cannot be held in the ON position during a fault condition—a critical safety feature in combat or remote operations. Operating reliably from -40°C to +85°C covers extreme deployment environments, and the 1500-amp AC and 7500-amp DC interrupt capacity handles catastrophic electrical faults without failure. The dual-pole, 277V AC and 65V DC rating supports both standard shipboard power systems and tactical DC platforms. Metal toggle actuator construction provides tactile feedback and durability under repeated cycling.

This breaker serves operators managing electrical systems on patrol craft, offshore platforms, command centers, and armored vehicles where electrical integrity directly impacts mission success. Maintenance crews and systems integrators rely on Blue Sea military-grade breakers to protect sensitive avionics, communications, propulsion, and weapon systems from the electrical faults that occur in high-vibration, high-stress operational environments. The compact 3 x 2 x 4-inch footprint and 0.35-pound weight integrate cleanly into control panels with space constraints.

Blue Sea Systems has established itself as the manufacturer of choice for military and maritime electrical protection, with products specified by naval architects, defense contractors, and coast guard vessels. The 7312's compliance with military electrical standards and proven performance record in saltwater and extreme-temperature service make it the proven solution for systems where conventional commercial breakers fall short.
