Blue Sea 7466 UL-489 Circuit Breaker - 30A Raised Rocker

The Blue Sea 7466 UL-489 Circuit Breaker 30A Raised Rocker is a marine-grade electrical protection device engineered for vessels requiring strict adherence to UL-489 marine specifications. Designed for Navy, Army, and Coast Guard applications, this 2-pole magnetic hydraulic breaker provides reliable overcurrent protection in harsh maritime environments where federal regulations under CFR 46 mandate certified electrical systems.

At 30 amps AC with a 250V maximum voltage rating, this breaker delivers robust protection for critical vessel circuits. The magnetic-hydraulic trip mechanism ensures trip-free operation, meaning the breaker cannot be held in the ON position during a fault condition—a critical safety feature in marine applications where personnel safety depends on instantaneous fault isolation. The raised rocker actuator provides tactile feedback and clear ON/OFF indication in dimly lit engine rooms or below-deck spaces. Terminal stud torque specification of 35 in-lb ensures secure connections that resist vibration loosening during extended ocean transits.

This breaker is specified for vessel electrical system upgrades, replacements, and new construction where documented compliance with UL-489 is required during Coast Guard or Naval inspections. Operators maintaining government vessels, commercial fishing boats, or military support craft rely on Blue Sea circuit breakers to meet regulatory standards without compromise. The 30A rating suits medium-draw circuits serving navigation systems, communications equipment, or auxiliary machinery where dependable protection is non-negotiable.

Blue Sea Systems is the industry standard for marine electrical protection, and their UL-489 certified breakers are approved for federal vessel service where no substitution is permitted. This specific model delivers the precision and reliability required in applications where electrical failure risks crew safety or mission success.
