About this product

The Blue Sea Systems A-Series Flat Rocker Circuit Breaker is a single-pole magnetic-hydraulic breaker for AC and DC marine electrical panels. It combines circuit protection and switching in one panel-mounted unit, making it useful for branch circuits where the breaker also needs to act as the on/off control.

This range covers multiple amperage ratings from 2.5A through 50A, with matching AC and DC ratings by variant. The breaker is rated for up to 240V AC and 32V DC, with interrupt capacity of 3000A at 125V AC, 1500A at 240V AC, and 5000A at 32V DC.

The flat rocker sits flush when it is in the ON position, which helps reduce accidental switching in tight helm, cabin, or electrical panel locations. A color indicator marks the OFF position, and the international ON/OFF symbols allow the breaker to be mounted vertically or horizontally without confusing the operator.

Key Features

  • Single-pole A-Series breaker for marine AC or DC branch circuits.
  • Magnetic-hydraulic, trip-free operation, so the rocker cannot be held ON during a fault current condition.
  • Flat rocker actuator sits flush in the ON position and shows a color indicator in the OFF position.
  • Rated up to 240V AC and 32V DC, with interrupt capacity of 3000A at 125V AC, 1500A at 240V AC, and 5000A at 32V DC.
  • Available amperage range runs from 2.5A to 50A for matching the protected load and branch-circuit wiring.
  • International ON/OFF symbols support vertical or horizontal panel mounting.
  • Uses #6-32 stainless steel mounting screws and #10-32 stainless steel terminal screws.
  • Operating temperature range is -40°C to 85°C, with 10,000 switching cycles at rated amperage and voltage.
