Blue Sea 1190 ELCI Main 30A Double Pole + 1 Position

The Blue Sea 1190 ELCI Main 30A Double Pole + 1 Position is a marinized electrical protection device engineered for comprehensive shore power safety on vessels of all sizes. Built to ABYC E-11 standards, this residual current circuit breaker delivers both overcurrent and ground-fault leakage protection—critical safeguards that prevent electrical fires, equipment damage, and personnel hazard in the harsh marine environment. Tactical and emergency response vessels, naval support craft, and commercial marine operations depend on this category of protection to maintain system integrity during extended dockside operations.

The unit incorporates a dual-pole main breaker configuration with a 30-ampere trip rating and a 30-milliampere leakage detection threshold, ensuring rapid isolation of shore power circuits at the first sign of ground fault or overcurrent condition. The double-pole design safeguards both hot legs of the AC mains simultaneously, while the single-position branch outlet accommodates downstream distribution requirements. Housed in a compact footprint (7 x 6 x 9 inches, weighing 1.6 lbs), the assembly delivers professional-grade electrical isolation without excessive deck or cabinet space consumption—a critical consideration on space-constrained vessel platforms.

Operators of research vessels, patrol craft, and mobile command centers benefit most from this main-breaker configuration, as it serves as the primary protective backbone for all shore power delivery systems. Installation at the shore-power inlet ensures that any electrical anomaly—whether ground leakage from deteriorating cable insulation, transformer faults, or accidental contact with seawater—trips the main and isolates the entire vessel before damage propagates through onboard electrical systems. Compliance-focused operations and insurance underwriters consistently specify Blue Sea ELCI protection for vessels requiring certified marine electrical safety and regulatory approval.
