Blue Sea Systems 7404 20A Flat Rocker Circuit Breaker

Blue Sea Systems 7404 A-Series Single Pole Flat Rocker Circuit Breaker (20A)

The Blue Sea Systems 7404 is a marine-grade single pole 20 Amp magnetic-hydraulic circuit breaker featuring a flush-mount flat rocker actuator. Designed for low-profile integration into Blue Sea Systems World market AC/DC distribution panels and custom marine switchboards, the flat rocker profile sits completely flush with the panel face when in the "ON" position, preventing accidental tripping caused by snagged gear, lines, or accidental bumps.

When tripped or switched off, a contrasting color band becomes exposed on the actuator to provide immediate visual indication of circuit status. Incorporating a true "Trip Free" mechanism, the internal contact assembly cannot be forcibly held closed against an active overcurrent fault or short circuit condition. Its magnetic-hydraulic sensing coil ensures precise amperage trip thresholds across extreme marine operating temperatures without ambient heat de-rating. 

Key Features

• Flush Flat-Rocker Actuator: Actuator stays flush in the "ON" position to eliminate snag hazards and accidental switching on 24-hour circuits.

• High-Visibility Status Indicator: Uncovers a colored indicator band when switched or tripped to the "OFF" position.

• Safety "Trip-Free" Design: Internal contacts open under fault conditions regardless of whether the actuator lever is held in place.

• Temperature-Stable Magnetic-Hydraulic Sensing: Maintains calibrated 20A trip performance from -40°C to +85°C.

• Dual AC/DC Rating: Fully qualified for both low-voltage DC marine circuits and 120/240V AC shore/generator sub-panels.
