Common Concerns Answered
Is the 35 AMP rating sufficient for all windlass motors?
While this 35 AMP breaker is suitable for many windlass applications, extremely high-draw windlass motors may require a higher amperage rating. Always verify your windlass's continuous and peak current draw against the breaker's specifications.
Can I find this breaker readily available?
Due to its specialized marine-grade features and reliability, this Lewmar circuit breaker can occasionally experience supply chain fluctuations. It's advisable to secure units when available for critical system installations.
Why is this marine breaker more expensive than a standard automotive breaker?
The higher cost reflects the critical marine-grade features such as its 'trip-free' design, IP67 waterproof rating, and ignition protection, which are essential for safety and longevity in a saltwater environment, unlike basic non-marine breakers.
Frequently Asked Questions
What is the maximum voltage this Lewmar circuit breaker can handle?
This Lewmar circuit breaker is rated for a maximum voltage of 48V DC.
Is this circuit breaker suitable for windlass applications?
Yes, this circuit breaker is specifically designed with a trip-free safety feature and is well-suited for demanding marine applications like windlass circuits.
What does 'trip-free' design mean for this breaker?
A 'trip-free' design means that the breaker cannot be manually held in the ON position if a fault condition exists that would cause it to trip, ensuring continuous protection.
Can this breaker be used in ignition-sensitive areas?
Yes, this circuit breaker is ignition protected, making it safe for installation in areas where flammable vapors may be present, such as near gasoline engines.
What type of circuit breaker class is this?
This Lewmar circuit breaker is classified as Type IIIC, featuring a thermally responsive bi-metal blade mechanism for overload protection.
