Blue Sea 15A C-Series Single-Pole Toggle Circuit Breaker
Blue Sea 15A C-Series Single-Pole Toggle Circuit Breaker
Magnetic Hydraulic Overcurrent Protection with White Toggle Switch

DESCRIPTION
Integrated Magnetic Hydraulic Overcurrent Protection and Switching
The Blue Sea C-Series 15A Single-Pole Toggle Circuit Breaker delivers dependable electrical protection and manual circuit control in a single, compact device. Engineered for demanding marine, RV, caravan, and off-grid industrial applications, this component eliminates the need for separate switches and fuse holders. By consolidating circuit switching and overcurrent protection, it simplifies switchboard wiring, reduces potential failure points, and saves valuable space behind your distribution panel.
Why Choose a Magnetic Hydraulic Circuit Breaker?
Standard thermal breakers rely on heat to trip, meaning their performance can fluctuate significantly in high-temperature environments like engine bays, enclosed battery boxes, or unventilated vehicle canopies. The Blue Sea C-Series utilises a magnetic hydraulic mechanism that responds purely to electrical current flow rather than ambient temperature. This ensures consistent, reliable trip profiles whether you are travelling through scorching Australian outback conditions or operating in cooler marine climates.
Additionally, the mechanism incorporates a trip-free design. This vital safety feature ensures that the internal contacts cannot be manually held closed during an active fault or short circuit. If an overcurrent event occurs, the breaker will trip and remain disconnected until the fault is resolved, significantly reducing the risk of wire insulation meltdowns, equipment damage, and electrical fires compared to basic fuse setups.
Key Features and Construction Benefits
- Dual-Function Design: Combines manual circuit switching and precise overcurrent protection into one integrated panel-mount unit.
- Magnetic Hydraulic Operation: Temperature-stable mechanism prevents nuisance tripping in hot enclosures while maintaining strict fault protection.
- Trip-Free Safety Mechanism: Internal contacts cannot be forced or held in the ON position while a dangerous overcurrent fault is present.
- Ergonomic White Toggle Switch: Provides clear visual status indication and positive tactile feedback for effortless manual control.
- Durable Phenolic Housing: Housed in a robust black thermoset plastic enclosure engineered to withstand harsh marine and mobile vibration.
- Secure Installation Hardware: Features threaded brass inserts for reliable panel mounting and heavy-duty rear screw terminals for solid cable termination.
Engineered for Harsh Marine and Off-Grid Environments
Electrical systems in boats, 4WDs, and off-grid solar installations are constantly subjected to vibration, moisture, and thermal cycling. The Blue Sea C-Series is constructed with a high-strength phenolic housing that resists heat and corrosion. The rear of the unit is equipped with heavy-duty screw terminals designed to clamp down securely on ring or fork terminals, minimising voltage drop and preventing loose connections that can cause localised heating over time.
At the front of the panel, the contrasting white toggle actuator makes it easy to identify tripped circuits at a glance, even in dimly lit cabins or utility canopies. The integrated threaded brass mounting inserts allow for straightforward, flush installation into custom dashboards, marine switchboards, or auxiliary power control panels.
Ideal Applications for 15A Circuit Protection
A 15A rating is well-suited for protecting medium-draw electrical branches and sensitive electronics. Common applications include:
- Marine navigation equipment, bilge pumps, and cabin lighting circuits
- Caravan and camper trailer 12V or 24V distribution panels, water pumps, and diesel heaters
- 4WD auxiliary battery canopies, work lights, and communication radios
- Off-grid solar control boards and industrial telemetry systems
