Blue Sea Systems 30A DC Circuit Breaker 285 Series, Surface Mount Ignition-Protected, Water-Resistant

The Blue Sea Systems 285-Series 30A surface-mount circuit breaker is a combined switch and medium-duty protective device that trips visibly and cannot be forced on when a fault occurs.

This compact surface-mount breaker pairs a manual on/off control with tailored overcurrent protection for marine and mobile electrical circuits. Built for use where space is limited, it’s ignition-protected and water resistant so you can mount it in engine compartments and other demanding locations. The 285-Series replaces older 185 models and keeps terminals accessible for straightforward wiring and maintenance.

How does this breaker protect my windlass or electric winch?

It interrupts excessive current by tripping when load limits are exceeded, preventing wiring and device damage from sustained overloads. The mechanism is trip-free, meaning you cannot hold the handle in the ON position if a fault persists, reducing the risk of continued overheating.

• Designed for medium-duty loads like windlasses and winches.
• Visible trip lever indicates a fault at a glance.
• Trip-free action prevents manual override during faults.
• 30 amp rating matches common marine accessory loads.

Where can I install this surface-mount breaker on my boat or vehicle?

The breaker’s ignition-protected and water-resistant construction lets you install it in engine rooms and other wet or fuel-vapor-prone areas. Its surface-mount design and face-located terminal studs make it easy to mount on bulkheads or flat panels without special recessing.

• Suitable for gasoline engine compartments (ignition-protected).
• Surface-mount form for bulkhead or panel installation.
• Terminal studs on the face for easier wiring access.
• Water-resistant housing tolerates marine environments.

What convenience and safety features does the 285-Series offer?

The unit combines switching and protection in a single device, reducing panel clutter and simplifying circuit design. Protective terminal caps guard against accidental contact and help reduce the chance of cross-current shorts, while the visible lever makes troubleshooting faster.

• Acts as both a switch and a circuit protector.
• Connected terminal caps reduce accidental contact risks.
• Visible lever provides quick fault indication for troubleshooting.
• Drop-in replacement for the earlier 185-series breakers.

How durable and supported is this product?

Built to withstand marine conditions and frequent use, the breaker comes backed by a five-year warranty for added ownership confidence. Its rugged construction and thoughtful features help ensure long-term performance in mobile electrical systems.

• Rugged housing resists moisture and vibration in marine use.
• Five-year warranty from Blue Sea Systems for peace of mind.
• Terminal caps and studs designed for reliable electrical connection.
• Replacement compatibility with older 185-series units.

Who is this for: The 285-Series 30A surface-mount circuit breaker is ideal for boat owners, marine electricians, and vehicle upfitters who need a compact, visible, and ignition-protected switch with built-in overcurrent protection. It’s well suited to protect windlasses, electric winches, and similar medium-duty accessories where ease of installation, safety, and reliable trip behavior matter.
