DESCRIPTION
Integrated Switching and Overcurrent Protection for High-Demand Systems
Managing high-current electrical systems in marine, RV, and off-grid environments requires reliable circuit protection that does not compromise on usability. The Blue Sea C-Series 50A AC Double-Pole Flat Rocker Circuit Breaker consolidates manual on-off switching and automatic overcurrent protection into a single, compact panel-mount device. By combining these two critical functions, system builders and marine electricians can eliminate the need for separate switches and fuse holders, simplifying wiring layouts and saving valuable dashboard or distribution panel space.
Engineered specifically for demanding loads, this unit is ideally suited for protecting large power inverters, marine bow thrusters, and anchor windlasses. Standard breakers often struggle with the initial inrush currents or continuous loads associated with these heavy-duty appliances, leading to nuisance tripping or premature wear. The C-Series design provides dependable operation under sustained heavy loads while offering immediate, accessible isolation at the main control panel whenever maintenance or emergency shut-off is required.
Ergonomic Flat Rocker and Trip-Free Safety Mechanism
In mobile and marine applications, accidental switching caused by movement, rough seas, or bumped consoles is a genuine operational hazard. This C-Series model addresses that risk through a specialized flat rocker actuator. When the circuit is live in the ON position, the rocker sits completely flush with the surrounding bezel. This low-profile posture prevents inadvertent actuation while maintaining effortless manual control when you intentionally need to isolate the circuit. For rapid visual diagnostics in dimly lit cabins or battery bays, the actuator exposes a clear colour indicator whenever the breaker is switched or tripped to the OFF position.
To further reduce the risk of electrical fires and equipment damage, the internal architecture features a dedicated trip-free mechanism. In the event of a short circuit or severe overload, the breaker will trip internally even if the exterior rocker is physically held or jammed in the ON position. This ensures that a dangerous fault condition cannot be manually overridden by an operator before the underlying electrical issue is resolved.
Key Features and Construction Benefits
- Dual-Function Design: Combines heavy-duty manual on-off switching with precision overcurrent protection in one unified footprint.
- Flush-Mount Flat Rocker: Remains level in the ON position to prevent accidental switching in high-traffic or high-vibration areas, with visual colour indication for the OFF state.
- Trip-Free Internal Operation: Prevents the contacts from being held closed manually during an active fault condition, safeguarding wiring and connected electronics.
- Heavy-Duty Terminal Hardware: Paralleled poles feature a robust 5/16-inch (approx. M8 or 8mm) stainless steel stud on the bus to accommodate heavy-gauge ring terminals securely.
- Precision Panel Mounting: Equipped with integrated brass threaded mounting inserts for secure, vibration-resistant installation into custom control panels and switchboards.
- High-Load Application Ready: Specifically rated to handle the inductive and high-current demands of inverters, windlasses, and bow thrusters.
Engineered for Secure High-Current Terminations
Inferior circuit protection devices often suffer from undersized terminals that generate excess heat and voltage drop when paired with thick cabling. The Blue Sea C-Series mitigates this risk by utilizing paralleled poles connected to a substantial 5/16-inch (approx. M8) stainless steel stud on the bus. This generous stud size allows installers to attach heavy-duty cable lugs directly to the breaker with proper torque, ensuring low-resistance connections that withstand harsh marine corrosion and mechanical vibration over time. Combined with the integrated brass mounting inserts, this breaker offers a clean, professional fit into any custom AC distribution panel.
Upgrade Your Circuit Protection
