Blue Sea 7289 C-Series Triple Pole Circuit Breaker - 80A

The Blue Sea 7289 C-Series Triple Pole Circuit Breaker – 80A is a marine-grade electrical protection device engineered to handle main AC circuit protection in 240-volt systems. Built to ABYC (American Boat and Yacht Council) standards, this triple-pole breaker provides 5,000-ampere interrupt capacity, making it the specification standard for larger marine and mobile power installations where reliable load switching and overcurrent protection are non-negotiable.

The three-pole configuration switches both hot lines and neutral simultaneously, essential for 240-volt AC main circuit applications where single-phase power management requires full circuit isolation. The white toggle mechanism is rated for 80 amperes at rated voltage, delivering the switching capacity needed for substantial shore power connections, generator-to-bus transitions, or high-load branch protection in vessels and off-grid power systems. The 5,000-ampere interrupt rating ensures the breaker can safely clear fault conditions without cascading failures, a critical safety margin in confined marine environments where electrical fires present severe risk.

This breaker serves operators managing complex electrical systems—marine electricians, liveaboard vessel owners, RV builders, and remote power installation professionals. The C-Series toggle design provides tactile, positive feedback during switching operations, allowing users to verify circuit status at a glance. Compact footprint (5 x 4 x 5 inches) fits standard breaker panels without requiring custom cutouts, simplifying retrofit and new installations. Blue Sea Systems' reputation for marine-duty electrical components ensures compatibility with industry-standard panel configurations and long-term reliability in salt-air and high-vibration environments.
