Blue Sea 3103 - C-Series ELCI Main Circuit Breaker, Double Pole 120V AC 50A

Blue Sea 3103 - C-Series ELCI Main Circuit Breaker, Double Pole 120V AC 50A

The Blue Sea 3103 - C-Series ELCI Main Circuit Breaker is an essential component for any boat's electrical system, providing overcurrent and leakage protection in accordance with ABYC E-11 for shore power protection. With a dual-pole design, this circuit breaker ensures that both positive and negative power lines are safeguarded against overloads, short circuits, and leakage to the ground. It is specifically designed for use in marine environments, meeting UL 1500 external ignition protection requirements to ensure safety in areas with gasoline engines or potential explosive environments.

This circuit breaker features a flat rocker actuator that resists accidental switching, and it trips instantly when it detects an overload, short circuit, or leakage. It is a magnetic hydraulic type, offering a trip-free mechanism that operates without any mechanical interference. The breaker can be installed in a power distribution panel, ensuring easy access and reliable protection. The device is rated for 50A amperage, 120V AC per pole, and has an interrupt capacity of 5000A, with an operating temperature range from -35°C to 66°C. With a long lifespan of up to 10,000 switching cycles, the Blue Sea 3103 is a durable and reliable choice for boat electrical systems.
