Common Concerns Answered
Are there any concerns about the reset mechanism?
While the push-button reset is effective and meets marine standards, some users accustomed to lever-style breakers might find it slightly less intuitive for rapid, immediate resets. However, its 'trip free' design ensures it cannot be manually overridden if a fault condition persists.
What about the California Prop 65 warning?
The California Proposition 65 warning is a standard disclosure for many products, including marine electrical components, and is related to potential exposure to certain chemicals. It does not inherently indicate a defect or unique hazard beyond what is common for similar products in the market.
Is the price a potential objection?
While priced at $64.99, the Blue Sea 2139 offers significant value through its marine-grade construction, ignition protection, and 'trip free' design, justifying the investment for critical electrical safety. Ensure this 20A rating aligns with your specific application's requirements.
