Common Concerns Answered
Is the price higher than generic circuit breakers?
While the Blue Sea 7189 may present a higher initial cost than non-marine grade alternatives, its premium construction, specific marine certifications (UL Recognized, ABYC), and proven reliability in harsh marine environments justify the investment for long-term electrical system integrity.
What is the California Proposition 65 warning about?
The California Proposition 65 warning is a standard disclosure required for products sold in California that may contain certain chemicals. Blue Sea Systems complies with these regulations, and it does not indicate a product defect or an increased risk beyond standard electrical components.
Why choose a 'Trip Free' circuit breaker?
A 'Trip Free' mechanism ensures that once a fault occurs and the breaker trips, it cannot be manually reset until the fault condition is cleared, preventing potential damage or hazards from attempting to force the circuit closed.
Frequently Asked Questions
What is the amperage rating of the Blue Sea 7189 circuit breaker?
The Blue Sea 7189 circuit breaker has a continuous amperage rating of 150 Amps.
Is the Blue Sea 7189 a direct replacement for the 185-series circuit breakers?
Yes, the Blue Sea 7189 is designed as a direct drop-in replacement for existing 185-series circuit breakers, simplifying upgrades and replacements.
What does 'Trip Free' mean for this circuit breaker?
'Trip Free' indicates that the circuit breaker's mechanism is designed to prevent it from being held in the closed position after a fault has occurred, ensuring it will trip and open the circuit regardless of manual attempts to reset it.
How can I tell if the Blue Sea 7189 circuit breaker has tripped?
The Blue Sea 7189 features a visible reset lever that clearly indicates an open condition when the breaker has tripped.
What is the voltage rating for the Blue Sea 7189 circuit breaker?
While the specific voltage rating is not explicitly detailed in the provided specifications, Blue Sea Systems circuit breakers are typically designed for standard marine DC voltage systems (e.g., 12V or 24V) and often AC applications as well, up to common marine system voltages. Refer to the product manual for precise AC/DC voltage limits.
