Blue Sea Systems 3091 C-Series ELCI Main Circuit Breaker

The Blue Sea Systems 3091 C-Series ELCI Main Circuit Breaker delivers critical shore power protection for marine electrical systems. Combining a high-quality circuit breaker with an Equipment Leakage Circuit Interrupter (ELCI), this device provides a critical layer of safety by detecting ground faults and leakage currents that can pose serious shock hazards aboard any vessel.

Designed to meet ABYC A-28 and UL 1053 standards, the C-Series ELCI monitors the entire AC electrical system and trips instantly when a leakage current of 30mA or more is detected — protecting passengers and crew from potentially lethal electric shock drowning (ESD). This unit is intended for installation as the main shore power disconnect at the electrical panel.

Key Features:

• Integrated ELCI (Equipment Leakage Circuit Interrupter) protection — 30mA trip threshold
• Complies with ABYC A-28 and UL 1053 safety standards
• C-Series modular design for clean, professional panel installations
• Functions as both main circuit breaker and ELCI protection in a single unit
• Two-pole design for single-phase 120V AC shore power systems
• TEST and RESET buttons for easy verification and manual reset
• Designed for use as a main shore power disconnect breaker
• Durable construction suited for the harsh marine environment

The Blue Sea Systems C-Series ELCI Main Circuit Breaker simplifies compliance with marina and Coast Guard requirements while keeping your vessel's AC electrical system safe. Its modular C-Series form factor integrates seamlessly with other Blue Sea Systems panel components for a professional, organized electrical installation.
