Blue Sea A-Series ELCI 30A 120v AC Double Pole Main Circuit Breaker

The Blue Sea A-Series ELCI 30A 120v AC Double Pole Main Circuit Breaker is a marine and mobile power system protection device designed for installations where reliable electrical safety is non-negotiable. Used extensively in tactical command centers, mobile operations platforms, emergency response vehicles, and off-grid deployments, this breaker protects both personnel and sensitive equipment from electrical faults. The ELCI (Equipment Leakage Circuit Interrupter) topology combines traditional overload and short-circuit protection with ground-fault detection, making it ideal for environments where wet conditions, equipment damage, or human contact with exposed conductors presents genuine risk.

The 30-amp 120-volt AC rating handles standard North American single-phase power distribution, while the double-pole configuration allows simultaneous disconnect of both conductors—a critical safety feature in military and law enforcement electrical architecture. The ELCI mechanism trips instantaneously on detection of leakage current to ground, eliminating the millisecond delays inherent in conventional ground-fault circuit interrupters and providing superior protection against arcing and personnel shock hazards. Front-panel mounting into a power distribution enclosure ensures accessibility for rapid manual reset during field operations, and the A-Series design integrates seamlessly with Blue Sea Systems modular panel systems used across military logistics and tactical command vehicle platforms.

Law enforcement mobile units, military field hospitals, tactical operations centers, and emergency management installations rely on this breaker to isolate power distribution sections without shutting down entire systems. Compatibility with standard DIN-rail and panel-mount enclosures allows retrofit into existing power architectures with minimal downtime. For operators managing complex electrical loads in austere or portable environments—where equipment redundancy and fast reset capability directly impact mission success—the Blue Sea A-Series ELCI 30A 120v AC Double Pole Main Circuit Breaker delivers proven reliability and compliance-grade personnel protection in a compact, field-serviceable package.
