Common Concerns Answered
Are these breakers hard to find in specific amperages?
While sourcing specific amperage ratings can occasionally be challenging, the Blue Sea 7258 offers a widely used 100A rating critical for main AC protection. Maintaining a relationship with a trusted marine supplier like BoatSupplyStore.com ensures access to essential components.
Is the price higher than non-marine breakers?
The Blue Sea 7258 is a premium marine-grade component designed for the demanding conditions of a vessel, which accounts for its price point. The investment is justified by its superior quality, enhanced safety features, and stringent ABYC certifications, offering long-term reliability and protection unmatched by standard breakers.
What makes marine-grade breakers more expensive?
Marine-grade components, like the Blue Sea 7258, are engineered with superior materials and undergo rigorous testing to ensure performance and safety in corrosive environments and under vibration. This includes certifications such as ABYC, which guarantee a higher level of reliability and fault tolerance essential for onboard electrical systems.
Frequently Asked Questions
What is the ampere interrupt capacity of the Blue Sea 7258 circuit breaker?
The Blue Sea 7258 circuit breaker has an Ampere Interrupt Capacity (AIC) of 5,000 Amperes.
Can this double pole breaker be used for 120V AC main protection?
Yes, the Blue Sea 7258 is designed for double pole 120V AC main protection, handling the switching of both the hot and neutral conductors.
