Marine Circuit Breaker – Push-to-Reset

Our Marine Push-to-Reset Circuit Breaker is a reliable, resettable fuse alternative designed for 12V/24V DC marine electrical systems. When a circuit is overloaded, the breaker “trips” and pops out – simply push the button back in to quickly restore power. No more fumbling with replacing fuses; this marine circuit breaker offers quick, front-panel resets for easy and safe power recovery. It’s built for the harsh marine environment, featuring a waterproof boot and corrosion-resistant components to ensure longevity on the water.

Key Features

Waterproof Boot Included: Each breaker comes with a threaded rubber boot that seals the button, keeping out moisture, spray, and dust. This ensures durability in marine environments and protects the breaker mechanism from corrosion.

Easy Push-to-Reset Design: If the circuit trips, a small plunger will pop out under the boot. Resetting is as simple as pressing the button back in – no tools or fuse replacements needed. This makes recovering from an overload or short circuit fast and hassle-free.

Compact Form Factor: With a body measuring only about 1.16″ x 0.56″ (29.5mm x 14mm) and a low profile on the panel, this breaker fits into tight spots. Its small size lets you mount multiple breakers in a limited space – perfect for dense switch panels where room is at a premium.

Standard Quick-Connect Terminals: Equipped with 0.250″ (6.35mm) male quick-disconnect terminals, the breaker allows for simple plug-in wiring. These common terminal sizes mean you can use readily available marine wiring connectors for a secure and quick installation.

Up to 32V DC Rated: Designed for 12V and 24V systems (max 32V DC), it’s ideal for most boat electrical setups. It can also handle up to 125VAC for versatility (switching is typically handled elsewhere). This thermal circuit breaker trips reliably to protect your circuits from overloads and can be reset countless times without needing replacement.

Built for Marine Switch Panels

This push-button circuit breaker is widely used on marine switch panels for branch circuit protection. Typically, it’s mounted beside or below each toggle or rocker switch on your boat’s control panel, providing quick access to reset if a circuit trips. In fact, you’ll find these resettable breakers on all Baywatt pre-wired marine panels – including our popular IP-Series, RSP-Series, and SPB-Series switch panels – a testament to their reliability and marine-grade performance.

• Marine Switch Panel with LED Circuit Breakers
• Rocker Switch Panels (4–6 Gang)

Whether you’re upgrading an older fuse-based panel or DIY-ing your own marine switch panel, these breakers make it easy to add professional-grade circuit protection. Replace those fragile fuses with this robust breaker to save time and frustration on the water – a simple push is all it takes to get your equipment running again. Plus, by standardizing on breakers, you’ll never be stuck searching for the right replacement fuse during a trip.

Easy Installation

Installing the Marine Push-to-Reset Circuit Breaker is straightforward and requires minimal tools. A standard 3/8″ (9.5mm) drill bit is all you need to create a mounting hole in your panel. The breaker’s threaded neck and included knurled nut allow you to securely fasten it to panels up to 1/4″ thick. Slide on the waterproof boot for a flush, sealed finish. The compact depth (about 1.3″ behind the panel) ensures it fits in tight dashboards or console spaces. With its quick-connect terminals, you can hook up the wiring in seconds – simply crimp on 1/4″ female spade connectors to your wires and plug them onto the breaker’s blades. It’s a plug-and-play solution that both novice boat owners and seasoned electricians will appreciate.

Tip: While these breakers protect individual circuits, remember to also protect your boat’s main power feed. It’s good marine practice to install a properly sized main fuse or circuit breaker near the battery to guard against high-current faults in the primary feed.

Available Amp Ratings & Selection Guide

We offer this marine circuit breaker in five amperage ratings to suit various electrical loads: 5A, 7A, 10A, 15A, and 20A. Choosing the correct breaker amperage is important for both safety and performance.

5 Amp (5A): Best for low-draw circuits such as LED lighting, electronic navigational aids, VHF radios, or fish finders.

7 Amp (7A): Ideal for moderate loads like cabin light arrays, small fans, or accessory sockets powering gadgets.

10 Amp (10A): Suitable for bilge blowers, stereo systems, sonar units, or multiple lights on one circuit.

15 Amp (15A): Perfect for pumps, windshield wipers, freshwater systems, and similar medium motors.

20 Amp (20A): Used for heavy-duty loads such as high-capacity bilge pumps, trim tab pumps, or windlass solenoid controls.

Selection Tips: Choose a breaker rating slightly above the device’s normal operating current but below the maximum current your wiring can safely carry. Never exceed the wire’s rating. If replacing a fuse, simply match the fuse’s amp rating with the same breaker value.

By selecting the proper amperage, you’ll avoid nuisance tripping while still safeguarding your boat’s wiring and equipment. Our range of 5A/7A/10A/15A/20A breakers gives you the flexibility to protect everything onboard from delicate electronics to higher-demand motors.

Equip your marine electrical panel with these push-to-reset circuit breakers and experience the convenience and peace of mind they provide. With their marine-focused design, easy installation, and straightforward operation, these breakers are an upgrade over traditional fuses in every way – keeping your boat’s electrical system safe, efficient, and easy to manage. Enjoy boating with fewer disruptions, knowing that if an overload occurs, a simple push gets you back up and running in no time. Safe voyages and power on!
