Lewmar Circuit Breaker - 35 AMP
Lewmar Circuit Breaker - 35 AMP — Product description
Why This Lewmar 35 AMP Circuit Breaker Stands Out for Marine DC Systems
In the demanding world of boating, where moisture, vibrations, and heavy loads are everyday realities, protecting your electrical circuits isn't just smart—it's essential for safety and reliability. The Lewmar 35 AMP circuit breaker steps up as a robust, panel-mounted solution designed specifically for DC systems up to 48 volts. Unlike basic fuses that might leave you stranded, this trip-free breaker combines seamless switching with automatic protection, making it a go-to choice for powering windlasses and other high-draw marine gear.
What sets it apart? Its waterproof construction shrugs off spray and submersion, while the ignition-protected design minimizes fire risks in engine compartments. Boaters trust it because it resets effortlessly after a trip, without the hassle of replacing blown fuses mid-voyage.
Key Features That Deliver Real-World Performance
- Versatile Voltage Handling: Safely manages DC systems up to 48 volts, perfect for modern marine setups with inverters or powerful accessories.
- Intuitive Single-Lever Operation: A clear, straightforward toggle that's easy to use even with gloved hands or in rough seas.
- All-in-One Functionality: Merges on/off switching with overcurrent protection, streamlining your panel and reducing wiring clutter.
- True Trip-Free Mechanism: Won't stay forced "ON" during overloads, ensuring your system shuts down safely every time.
- Ignition Protection: Complies with strict standards to prevent sparks in fuel-rich environments, a must for gasoline-powered boats.
These aren't just specs on paper—they translate to peace of mind when you're anchoring in a blow or winching aboard heavy ground tackle.

Installation Tips for Seamless Integration
Getting this breaker up and running is straightforward, but a few pro tips ensure optimal performance. Panel-mount it securely using the provided holes, routing heavy-gauge wire directly to your windlass or motor terminals. Always match wire size to the 35A rating—think 8-10 AWG for runs under 10 feet. Test the trip function post-install by simulating an overload with a multimeter, and label your panel clearly for quick reference underway.
Pro boaters often pair it with Lewmar windlasses for matched protection, but it shines on thrusters, pumps, or any intermittent high-amp load. Remember, regular inspections catch corrosion early, extending its lifespan in salty environments.
Common Applications and Long-Term Benefits
Ideal for windlass circuits where sudden high inrush currents from stalled motors demand fast, reliable protection. It's also a solid pick for bow thrusters, livewell pumps, or lighting arrays on larger vessels. Over time, the trip-free design saves money—no more fuse shopping—and its durability means fewer replacements, even after years of hard use.
By preventing wire meltdown or battery drain from faults, it safeguards your investment in electronics and keeps you boating instead of troubleshooting.
Frequently Asked Questions
Is this circuit breaker suitable for AC systems?
No, it's designed exclusively for DC systems up to 48 volts, common in marine applications like boats and RVs.
What makes it 'trip-free' and why does that matter?
Trip-free means it automatically disconnects during faults and can't be held ON manually, preventing damage from sustained overloads—crucial for safety on the water.
Can I use this for my windlass?
Absolutely—it's optimized for windlass circuits, handling the high startup amps without nuisance tripping.
Is it waterproof for deck mounting?
Yes, its waterproof build protects against spray and splashes, though it's best panel-mounted in a protected enclosure.
How do I reset it after tripping?
Simply flip the lever fully OFF, wait a moment, then switch back ON. Investigate the cause first to avoid repeats.
Does it meet marine safety standards?
Yes, ignition protection and Type III classification align with ABYC and ISO marine requirements for reliable operation.
