Blue Sea Systems offers a range of C-Series circuit breakers in various amperage ratings. Availability of specific ratings may vary, so consult the full product line to find the precise breaker that matches your vessel's electrical load requirements and consult with a qualified marine electrician.
Are there any compliance issues I should be aware of?
This circuit breaker meets ABYC requirements for 120/240 Volt 50 Ampere main protection, ensuring compliance with recognized marine electrical standards. Proper installation by a qualified professional is crucial for maintaining these safety certifications.
Frequently Asked Questions
What is the ampere interrupt capacity of the Blue Sea 7289 circuit breaker?
The Blue Sea 7289 C-Series Triple Pole Circuit Breaker has an ampere interrupt capacity of 5,000 Amperes.
Can this triple pole breaker be used for a 120-volt AC main circuit?
While designed for 240V AC main circuits, a triple pole breaker can be configured to switch two separate 120V circuits or a 120/240V split-phase system, but its primary application and safety certifications are for 240V main protection. Consult your marine electrician for specific application advice.
What does 'Trip Free' design mean for this circuit breaker?
A 'Trip Free' design means the circuit breaker cannot be held in the ON position by the user if a fault condition (overcurrent or short circuit) is present, ensuring that the circuit is interrupted for safety.
Is this circuit breaker suitable for 240-volt AC main circuits?
Yes, the Blue Sea 7289 is specifically designed and rated for 240-volt AC main circuit protection in marine applications.
What is the purpose of the triple pole configuration in this breaker?
The triple pole configuration is used to simultaneously switch all three conductors (hot-to-hot and neutral if applicable in a specific system configuration, though this breaker is primarily for two hot conductors in a 240V circuit) in a 240-volt AC system, ensuring complete isolation and protection.
