Blue Sea C-Series ELCI 50A 120v AC Double Pole Main Circuit Breaker

The Blue Sea C-Series ELCI 50A 120v AC Double Pole Main Circuit Breaker is designed for marine and tactical power distribution, specifically for shore-power-fed systems that require dual-pole protection. This breaker is ideal for use in vessels, expeditionary command posts, and mobile tactical operations centers, providing essential safety features for electrical systems.

This circuit breaker offers simultaneous over-current and ground-fault leakage detection across both conductors, which helps to eliminate single-point failure modes. It is built to meet ABYC E-11 standards and UL 1500 external ignition protection requirements. The C-Series architecture employs electromagnetic and thermal trip mechanisms that work together to ensure disconnection during overload or short-circuit conditions.

Tactical teams operating from shore power will find this breaker essential for maintaining equipment safety and reliability. The integrated ELCI monitors differential current flow, which is crucial for detecting insulation breakdown. With a weight of 0.85 lbs, it is designed to minimize installation penalties in weight-sensitive applications.
