Common Concerns Answered
Is the price justified compared to standard fuses?
While the initial purchase price may be higher than disposable fuses, the resettable nature and enhanced durability of the Blue Sea 7068 circuit breaker offer long-term cost savings and superior protection, aligning with ABYC standards.
What happens if I choose the wrong amperage?
Selecting the correct amperage is critical for effective circuit protection. An amperage rating too low will cause nuisance tripping, while a rating too high will fail to protect the circuit from dangerous overloads.
How does this offer better protection than a fuse?
Unlike fuses which are destroyed by an overload and require replacement, this circuit breaker can be manually reset after tripping, providing immediate restoration of power once the fault is cleared and offering a more robust and repeatable protective function.
Frequently Asked Questions
What is the difference between a circuit breaker and a fuse?
A fuse is a sacrificial device that contains a wire designed to melt and break the circuit when excessive current flows through it. A circuit breaker, like the Blue Sea 7068, is a resettable switch that automatically interrupts the circuit under fault conditions and can be manually reset to restore power after the fault is cleared.
Can this circuit breaker be used as a replacement for an ATO or ATC fuse?
Yes, the Blue Sea 7068 is specifically designed as a low-profile, drop-in replacement for standard ATO and ATC blade style fuses, maintaining compatibility with existing fuse blocks.
What is the maximum voltage this circuit breaker can handle?
This circuit breaker is rated for a maximum voltage of 28V DC, making it suitable for standard direct current marine electrical systems.
How do I reset this circuit breaker?
To reset the Blue Sea 7068, simply push the button on the face of the breaker. If the circuit is still experiencing an overcurrent condition, it will trip again.
What is the interrupt capacity of this circuit breaker?
The Blue Sea 7068 has an interrupt capacity of 2000 Amps at 28 Volts DC, meaning it can safely interrupt a fault current of this magnitude without sustaining damage.
