Blue Sea 3566 AC Toggle Source Selector (230V) - 2 Sources + 9 Positions

The Blue Sea 3566 AC Toggle Source Selector (230V) is a dual-source AC power distribution system purpose-built for applications requiring seamless switching between two independent AC power sources while maintaining absolute safety isolation. This marine-grade electrical component integrates two 16-ampere double-pole circuit breakers with six 8-ampere single-pole circuit breakers, delivering a maximum panel amperage rating of 50 amperes. The unit prevents simultaneous connection of both AC sources through a mechanical lockout slide, a critical safety feature that protects equipment and personnel in mission-critical power management scenarios.

The selector's specifications reflect hardened electrical design standards. The double-pole AC main circuit breakers provide simultaneous protection on both hot and neutral conductors, exceeding single-pole protection common in consumer-grade equipment. The integrated red reverse-polarity indicating LED signals dangerous wiring faults before they compromise connected systems. All hot, neutral, and safety ground connections employ fail-safe construction appropriate for 230-volt European AC mains. The white toggle switches provide positive tactile feedback during source transitions, critical in high-noise operating environments where visual confirmation alone may be insufficient.

This selector serves electrical systems in marine vessels, mobile command centers, and remote power distribution networks where redundant AC sources—such as shore power and onboard generators—must remain isolated yet switchable. The 9-position architecture accommodates multi-circuit branch distribution, allowing selective load management across independent breaker banks. The 50-ampere maximum panel rating suits mid-sized power systems while the modular breaker configuration enables customization of circuit protection schemes. Operators and technicians managing complex electrical architectures depend on the mechanical lockout and dual main breaker design to prevent catastrophic faults during source transitions.
