Blue Sea Systems A-Series Raised Rocker Circuit Breaker, Double Pole, 120/240V AC, 32V DC, Magnetic Hydraulic, Trip-Free

Overview

The Blue Sea Systems A-Series Raised Rocker Circuit Breaker is a double pole magnetic hydraulic circuit breaker that combines circuit protection and switching in one panel-mounted unit. It is built for AC and DC marine electrical panels, with ratings across this range from 15A to 50A and maximum voltage ratings of 120V AC, 240V AC, and 32V DC.

This raised rocker version is commonly used where a breaker also needs to act as a clear manual switch at the panel. The color actuator shows the OFF position, while international ON/OFF symbols make the breaker readable whether the panel is arranged vertically or horizontally.

The trip-free mechanism is important on boats because the breaker cannot be held ON during a fault current condition. That matters in shore power, inverter, generator, and other onboard circuits where proper overcurrent protection helps protect wiring and connected equipment.

Key features

• Double pole breaker for switching and protecting two conductors in AC or DC panel applications.
• Magnetic hydraulic trip-free design prevents the breaker from being forced ON during a fault current condition.
• Raised rocker actuator gives clear panel operation and is easy to identify at the electrical distribution panel.
• Color actuator indicates the OFF position for quick status checks at the helm, cabin panel, or service area.
• Supports 120V AC, 240V AC, and 32V DC systems within the correct amperage configuration.
• Interrupt capacity is rated at 3000A at 240V AC, 1500A at 240V AC under TUV rating, and 5000A at 32V DC.
• Operating temperature range of -40° C to 85° C suits enclosed marine panels, cabins, and machinery spaces.
• Stainless steel #6-32 mounting screws and #10-32 terminal screws support panel installation in the marine environment.
• UL 1077 recognized, CE marked, CSA certified, and TUV certified for broad panel compliance requirements.

Variants

This product family varies by amperage, with configurations covering 15A, 16A, 20A, 30A, 32A, 40A, and 50A. The correct amperage depends on the protected circuit, the expected load, and the ampacity of the installed wiring.

Across the listed configurations, the shared format is a double pole A-Series raised rocker breaker for AC/DC panel use. The amperage rating is the key difference to confirm before installation, especially when replacing an existing breaker in a Blue Sea Systems panel or matching protection to a new circuit.

Installation and setup

This breaker is intended for installation in a compatible marine electrical panel. Match the amperage to the circuit design, wire size, and expected load rather than choosing by equipment size alone. For motor, pump, compressor, and other inductive loads, start-up current should be considered when sizing the circuit protection.

Use the specified screw torques during installation: 6 in-lb for the mounting screws and 14 in-lb for the screw terminals. Correct torque helps maintain a secure connection in panels exposed to vibration and repeated service access.

Compatibility and use on board

This breaker is a practical match for boat owners, installers, and refit projects that need a resettable breaker with a built-in switching function. It fits applications where a circuit must be turned off from the panel and protected from overcurrent without adding a separate switch.

Common onboard use areas include AC main protection, distribution panels, inverter or charger panels, and DC circuits that require a double pole breaker within the voltage and amperage limits of the selected variant.
