More Details on Our Top Picks
Five Oceans 80 Amps Circuit Breaker with Manual Reset Button, 12V Waterproof IP67, Surface Mount
The Five Oceans 80 Amp circuit breaker excels in protecting higher-capacity windlasses thanks to its robust 80-amp rating. Its waterproof IP67 rating makes it suitable for harsh marine conditions, and the surface mounting design simplifies installation. Compared with the South Bend breaker, it offers a higher current threshold but is limited to 12V systems, which means it’s better suited for larger, 12V systems on bigger boats. The inclusion of a protective stud insulator adds reliability, but its focus on 12V systems means it isn’t ideal for multi-voltage setups.
Pros:- High 80 Amp protection for demanding windlasses
- Waterproof IP67 rating for marine durability
- Easy to install with surface mounting
- Includes protective stud insulator
Cons:- Limited to 12V systems only
- Not suitable for systems requiring higher voltages
- No overload protection beyond circuit breaking
Best for: Larger boats with high-capacity windlasses requiring robust 12V protection
Not ideal for: Smaller boats or systems with voltages above 12V
- Amperage:80 Amps
- Voltage:12 Volts
- Waterproof Rating:IP67
- Mounting Type:Surface Mount
- Manual Reset:Yes
- Certifications:None specified
Our verdict“This breaker is ideal for boat owners needing high current protection in a waterproof, marine-ready package, but only if running a 12V system.”
South Bend Components SBC-WK-CB-60A Replacement 60 Amp Marine-Grade Circuit Breaker
The South Bend 60 Amp breaker provides a solid choice for boaters needing compatibility across various voltage ranges, from 12V up to 48V. Its marine-grade waterproof construction ensures durability, and the manual reset switch allows quick system control. Unlike the Five Oceans breaker, it is rated for a slightly lower current, but its broader voltage range makes it adaptable to different systems, including trolling motors, solar setups, or windlasses of smaller to medium size. The surface mount design simplifies installation, but it requires proper wiring and may lack overload protection features beyond the circuit breaker itself.
Pros:- Marine-grade waterproof construction
- Manual reset with switch functionality
- Wide voltage compatibility (12V-48V)
- Easy to install with surface mount
Cons:- Limited to 60 Amp applications
- No built-in overload or fuse protection
- Requires correct wiring for safety
Best for: Boats with multiple voltage systems or smaller windlasses needing reliable protection
Not ideal for: High-current, 12V-only applications requiring more than 60A
- Current Rating:60 Amps
- Voltage Range:12V-48V DC
- Waterproof Rating:IP67
- Mount Type:Surface Mount
- Manual Reset:Yes
- Certifications:UL1077, CSA C22.2
Our verdict“This breaker suits boaters looking for a versatile, waterproof circuit breaker that can handle varying voltage setups, but it’s best for systems under 60A.”

Factors to Consider When Choosing Windlass Circuit Breaker Kit
When selecting a windlass circuit breaker kit, it’s vital to match the breaker’s specifications with your windlass’s power needs and your boat’s electrical system. Key factors include current capacity, waterproof rating, ease of installation, and compatibility with your system’s voltage. Proper protection ensures safety and longevity for your windlass and overall electrical setup.
Current Capacity and Voltage Compatibility
Choosing a breaker with the right amperage is critical. Too low, and it won’t protect your windlass from overloads; too high, and it might not trip in time to prevent damage. The Five Oceans model offers high capacity for large windlasses, but is restricted to 12V systems. The South Bend breaker’s broader voltage range makes it suitable for varied setups, yet it caps at 60A, which may be insufficient for very high-power windlasses. Always match your breaker’s specs to your windlass’s requirements to avoid under- or over-protection.
Waterproof and Durability Features
Marine environments demand waterproof and corrosion-resistant components. The IP67 rating on both options indicates protection against water immersion and dust, but consider additional features like protective covers or insulators for long-term durability. These factors help prevent failures due to moisture ingress, which is common in marine settings.
Ease of Installation and System Compatibility
Surface mount designs are generally straightforward to install, but verifying the size and wiring requirements is essential to ensure compatibility with your existing setup. The South Bend breaker’s wider voltage range provides more flexibility, especially if you plan to upgrade or modify your electrical system later. Proper wiring and grounding are vital for safety, so choose a product with clear instructions and reliable build quality.
Frequently Asked Questions
What is the main difference between these two circuit breakers?
The primary difference lies in their current ratings and voltage compatibility. The Five Oceans breaker is rated for 80 amps at 12V, making it better suited for larger, high-current windlasses, while the South Bend breaker offers 60 amps and a wider voltage range of 12V-48V, providing more versatility but with a lower maximum current threshold.
Can I use these breakers for systems above 12V?
The Five Oceans breaker is specifically designed for 12V systems, so it isn’t suitable for higher voltage setups. The South Bend breaker, however, can handle up to 48V, making it a better choice for boats with multiple voltage systems or future upgrades.
Are these breakers waterproof enough for marine use?
Yes, both options feature waterproof ratings (IP67), ensuring they resist water ingress in typical marine conditions. However, for prolonged exposure or extreme environments, additional protective measures, such as covers or sealed enclosures, are recommended to maximize longevity.
Do these breakers provide overload protection?
Both breakers serve as protection devices that trip when the current exceeds their rated capacity. They do not include fuses or additional overload protections, so proper wiring and system design are essential to prevent damage or safety hazards.
How difficult is it to install these circuit breakers?
Installation is generally straightforward due to their surface mount design and standard wiring terminals. Ensuring correct wiring, grounding, and matching the amperage to your windlass’s needs is crucial for safety and reliable operation. Consulting the product instructions and possibly a professional is advisable for optimal results.
Conclusion
For boat owners with large windlasses or systems operating exclusively at 12V, the Five Oceans 80 Amp Circuit Breaker offers the high-current protection needed for demanding applications. Conversely, those with smaller systems, multiple voltages, or seeking a more adaptable solution should consider the South Bend 60 Amp Marine-Grade Breaker. Both products deliver waterproof reliability, but your specific system size and voltage compatibility will guide the best choice.
