A Series Toggle Double Pole Circuit Breaker

The Blue Sea Systems A-Series Double Pole Toggle is a magnetic hydraulic circuit breaker for marine electrical panels, combining manual switching and circuit protection in one panel-mounted device. It is a double-pole toggle breaker, commonly used for AC main circuit protection where both poles need to be controlled together.

This A-Series range is available in black or white with amperage options from 10A to 50A. Verified electrical ratings include support for 120V AC, 240V AC, and 65V DC systems, with an interrupt capacity of 3000A at 120V AC, 3000A at 240V AC, and 7500A at 65V DC.

The trip-free mechanism means the breaker cannot be held ON during a fault condition. That matters in a boat panel because the breaker remains a protective device, not just a switch, when a short circuit or overload occurs.
