Blue Sea 80A AC C-Series Double-Pole Flat Rocker Circuit Breaker
Blue Sea 80A AC C-Series Double-Pole Flat Rocker Circuit Breaker
Trip-Free Overcurrent Protection & 5/16" (M8) Studs for Inverters

DESCRIPTION
Integrated High-Current Switching and Overcurrent Protection
The Blue Sea C-Series 80A AC Double-Pole Flat Rocker Circuit Breaker provides a streamlined, heavy-duty solution by combining manual ON/OFF switching and reliable overcurrent protection into a single panel-mounted device. Engineered for demanding electrical architectures, this unit eliminates the need to wire separate high-amperage switches and fuse blocks, simplifying your distribution board layout and reducing potential points of electrical failure. It is specifically suited for high-draw appliances and critical sub-circuits such as power inverters, marine bow thrusters, and anchor windlasses.
Ergonomic Flat Rocker Design for Enhanced Safety
In mobile and marine environments, accidental disconnection of critical circuits is a common hazard caused by bumps, snagged clothing, or shifting gear. The C-Series flat rocker actuator directly addresses this risk. When engaged in the ON position, the low-profile rocker sits flush with the surrounding frame, preventing inadvertent switching. When switched or tripped to the OFF position, a brightly coloured actuator surface becomes clearly visible, providing instant visual confirmation of the circuit status even in dimly lit cabins or equipment bays.
Fail-Safe Trip-Free Mechanism
Safety during an electrical fault is paramount when managing high-capacity power systems. This circuit breaker features an internal trip-free mechanism, which means the internal contacts cannot be manually held closed during an active overcurrent or short-circuit condition. Unlike inferior grade switches that may weld shut or allow operators to force power into a compromised line, this trip-free design ensures the circuit remains isolated until the fault is properly resolved, significantly reducing the risk of cable overheating and electrical fires.
Robust Construction and High-Amperage Connectivity
Designed to handle substantial electrical loads without excessive voltage drop or thermal buildup, the rear of the breaker features paralleled poles connected via a heavy-duty bus. The 5/16-inch (approx. M8) terminal studs accommodate large-gauge cable lugs, ensuring secure mechanical and electrical connections capable of withstanding continuous vibration. Additionally, integrated brass threaded mounting inserts allow for secure front-panel screw installation, offering superior durability compared to standard plastic clip-in breakers.
Key Features
- Dual Functionality: Combines manual ON/OFF circuit switching with automatic 80A overcurrent protection in one compact footprint.
- Flush ON Actuator: Low-profile flat rocker sits flush when active to prevent accidental switching in tight spaces.
- Visual Status Indicator: Colour-coded actuator clearly displays the OFF position for immediate troubleshooting and safety checks.
- Trip-Free Operation: Internal mechanism disconnects and cannot be held closed during an active fault condition.
- Heavy-Duty Terminals: Equipped with 5/16-inch (approx. 8mm / M8) rear terminal studs on the bus for paralleled poles and secure high-current lug terminations.
- Secure Panel Mounting: Features integrated brass threaded inserts for reliable front-panel installation and clearly printed amperage ratings for easy identification.
Ideal Applications
Whether you are building a custom marine switchboard, upgrading an off-grid caravan power system, or fitting out a commercial utility vehicle, the Blue Sea C-Series breaker delivers professional-grade circuit management. It is widely used for isolating and protecting high-demand circuits, including AC main feeds, large inverter systems, winches, and hydraulic pumps.
