Common Concerns Answered
Will this 35 AMP breaker be sufficient for my large windlass motor?
The 35 AMP rating is suitable for many common windlass applications, but for extremely high-draw motors, you may need to consult your windlass manufacturer's specifications or consider a higher amperage breaker. This model is specifically designed for demanding marine use, offering critical safety features.
Is the price justified for this circuit breaker?
While seemingly higher than basic non-marine breakers, the price reflects the specialized marine-grade construction, including ignition protection, waterproof sealing, and a trip-free mechanism, which are critical for safety and longevity in harsh maritime environments.
Is availability sometimes an issue for this product?
Due to its specialized nature and high demand in marine applications, availability can occasionally fluctuate. We recommend purchasing when in stock to ensure you have this essential component for your vessel.
Frequently Asked Questions
What is the maximum voltage this Lewmar circuit breaker can handle?
This Lewmar circuit breaker is designed to handle DC systems up to a maximum voltage of 48V DC.
Is this circuit breaker suitable for windlass applications?
Yes, this circuit breaker is specifically designed for demanding marine environments and is an excellent choice for protecting high-draw applications such as windlass circuits.
What does 'trip-free' design mean for this breaker?
