Blue Sea 7446 UL-489 Circuit Breaker - 100A Flat Rocker

The Blue Sea 7446 UL-489 Circuit Breaker - 100A Flat Rocker is a marine-grade electrical protection device engineered to meet stringent U.S. Navy, Army, and Coast Guard specifications. This 100-amp DC circuit breaker is designed for critical applications aboard naval vessels, commercial marine platforms, and other installations governed by Code of Federal Regulations Title 46 (CFR 46). When regulatory compliance and reliability in harsh marine environments are non-negotiable, this UL-489 certified breaker provides the dependable overcurrent protection your electrical system demands.

Built to exacting military and maritime standards, the 7446 features a flat rocker actuator design that enables fast, intuitive manual operation even in confined spaces or low-visibility conditions. The UL-489 certification ensures the breaker delivers precise trip characteristics at 100 amperes, protecting DC electrical systems from overload and short-circuit faults. This robust construction withstands the corrosive salt-air environment, thermal cycling, and vibration inherent to naval and offshore applications, making it a permanent fixture in mission-critical power distribution panels where replacement or failure is not an option.

Marine electricians, naval maintenance personnel, and vessel builders rely on the Blue Sea 7446 for retrofit and new-build installations that must satisfy government procurement standards. The compact 3 x 2 x 5-inch footprint integrates seamlessly into standard electrical panels aboard ships, submarines, and offshore platforms. Whether you're upgrading an existing distribution system or designing a new vessel-wide power architecture, this UL-489 circuit breaker ensures your DC circuits remain protected without compromise to safety, compliance, or operational integrity.
