DESCRIPTION
Heavy-Duty 150A Circuit Protection and Switching for Marine and Off-Grid Systems
The Blue Sea 285-Series 150A Surface Mount Thermal Circuit Breaker delivers reliable overcurrent protection and manual switching in a single, compact unit. Engineered specifically for harsh marine, RV, and off-grid electrical environments, this heavy-duty breaker safeguards high-amperage wiring and critical appliances from damage caused by electrical shorts or sustained overloads. By combining switching and circuit protection into one device, it simplifies system layouts and eliminates the need for separate battery switches and fuse holders.
Certified Ignition Protection for Marine Safety
When installing electrical components in enclosed spaces or aboard petrol-powered vessels, safety compliance is critical. This 285-Series circuit breaker is fully ignition protected and meets rigorous SAE J1171 external ignition protection requirements. This certification ensures the device will not ignite surrounding flammable gases or vapours if a high-current fault occurs, making it safe for installation in boat bilges, engine compartments, and battery boxes alongside dual battery systems.
Superior Reliability Over Standard Breakers
Inferior circuit breakers often suffer from voltage drop, nuisance tripping, and terminal corrosion when exposed to moisture and vibration. Furthermore, low-grade breakers can sometimes be forced into the closed position during an active fault, creating a severe fire risk. The Blue Sea 285-Series eliminates these hazards with a precision-engineered "trip-free" mechanism. This design ensures the breaker cannot be held closed manually while a fault current persists, protecting your cabling and equipment until the underlying electrical issue is resolved.
- Dual-Function Design: Combines 150A thermal overcurrent protection with manual on/off switching via a recessed red push-to-trip button.
- High-Visibility Status Indicator: Features a bright yellow reset lever that clearly indicates when the circuit is open, allowing for rapid visual inspection in dark compartments.
- Trip-Free Safety Mechanism: Prevents the circuit from being held closed during an active overcurrent condition, mitigating fire and equipment damage risks.
- Marine-Grade Construction: Weather-resistant housing and heavy-duty stainless steel connection studs resist corrosion in coastal and high-humidity environments.
- Integrated Terminal Protection: Equipped with flexible rubber terminal caps to shield live connections from accidental shorting and debris.
- SAE J1171 Compliant: Certified ignition protected for safe installation aboard petrol-powered boats and enclosed battery compartments.
Built for Demanding Australian Conditions
From corrugated outback tracks to salt-laden marine environments, electrical connections are constantly subjected to vibration and moisture. The Blue Sea 285-Series features pre-drilled mounting holes for secure surface installation on flat panels or bulkheads. Its heavy-duty stainless steel terminal studs provide robust mechanical strength for large-gauge battery and inverter cables, while the integrated flexible rubber boots cover the exposed lugs to prevent accidental short circuits from shifting tools or equipment.
Ideal Applications
This 150A surface mount breaker is suited to a wide variety of high-current DC electrical systems, including:
- Main circuit protection for 12V and 24V house battery banks in caravans, camper trailers, and motorhomes
- Safe isolation and overcurrent protection for DC-DC chargers, power inverters, and windlasses
- Marine electrical systems, particularly in engine bays and bilge areas on petrol-powered boats
- 4WD dual battery setups, winch control circuits, and commercial vehicle auxiliary power systems
