About this product

The Blue Sea Systems A-Series Flat Rocker Circuit Breaker is a double-pole magnetic hydraulic breaker for marine electrical panels, combining manual switching and circuit protection in one panel-mounted unit. This version family uses a flat rocker actuator, supports both AC and DC systems, and is rated up to 120V AC, 240V AC, and 32V DC.

The double-pole format is commonly used where two conductors need to be opened together, such as AC main circuit protection on a boat. Its trip-free mechanism means the breaker cannot be held in the ON position during a fault condition, which helps protect wiring and connected equipment when current rises beyond the selected rating.

The actuator shows the OFF position clearly, and international ON/OFF symbols allow the breaker to be mounted vertically or horizontally. It is built for panel installations using #6-32 stainless steel mounting screws and #10-32 stainless steel terminal screws, with an operating temperature range from minus 40°C to 85°C.

Key Features

• Double-pole A-Series breaker for circuits where two poles must switch and trip together.
• Magnetic hydraulic, trip-free circuit breaker type for switching and circuit protection in one device.
• Maximum voltage ratings of 120V AC, 240V AC, and 32V DC for use across common marine electrical systems.
• Interrupt capacity of 3000A at 240V AC, 1500A at 240V AC TUV, and 5000A at 32V DC.
• Flat rocker actuator sits flush in the ON position to help reduce accidental switching at the panel.
• Color actuator indicates the OFF position for quick status checks at the helm, nav station, or electrical panel.
• International ON/OFF symbols support either vertical or horizontal mounting.
• Meets ABYC standards and carries UL 1077 recognition, TUV certification, CE marking, and CSA certification.
• Rated for 10,000 switching cycles for repeated use as both a breaker and a switch.
