Description
Blue Sea 7290 100A Triple Pole Breaker | Boat Supply Store
Secure your vessel's 240-volt AC power distribution with the Blue Sea 7290 C-Series Triple Pole Circuit Breaker, engineered for critical main protection. This unit offers a robust 5,000 Ampere interrupt capacity, safeguarding against severe fault currents common on larger yachts or vessels with high-draw AC systems. Its triple-pole configuration ensures simultaneous tripping of all 240V AC lines and the neutral conductor, preventing dangerous imbalances, while the 'Trip Free' mechanism guarantees operation during fault conditions, crucial for compliance with ABYC standards.
Key Features

Common Concerns Answered
How common are stockouts for specific Blue Sea circuit breaker amperages?
Due to Blue Sea Systems' strong reputation for quality and reliability in marine electrical components, certain amperage ratings like the 100A can experience high demand, occasionally leading to temporary stock limitations. It is advisable to plan purchases in advance.
Is the 'Trip Free' mechanism on this breaker difficult to engage?
The 'Trip Free' design is a critical safety feature engineered to prevent manual engagement during fault conditions. While some users may initially find it slightly stiffer than a standard breaker, this is intentional for absolute safety and reliability when protecting your electrical system.
Will this breaker fit my existing panel if it uses a different brand?
The Blue Sea 7290 is designed to fit standard marine panel cutouts for C-Series breakers. However, always verify dimensions and mounting specifications against your existing panel's requirements to ensure precise compatibility.
Frequently Asked Questions
What is the ampere interrupt capacity of the Blue Sea 7290 circuit breaker?
The Blue Sea 7290 C-Series Triple Pole Circuit Breaker has an ampere interrupt capacity of 5,000A, which is the maximum fault current it can safely interrupt.
Can this triple-pole breaker be used as a 120-volt AC main circuit breaker?
While rated for 120/240V AC, this triple-pole breaker is primarily designed for 240V AC main protection where all hot lines and the neutral need to be switched simultaneously for safety. For 120V AC main protection, a single or double-pole breaker is typically used, depending on the system configuration.
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 when an overcurrent or short-circuit condition is detected. It will trip regardless of manual force, ensuring protection against dangerous electrical faults.
What is the purpose of a triple-pole circuit breaker in a 240-volt AC system?
A triple-pole circuit breaker is used in 240-volt AC systems to simultaneously disconnect all three conductors (typically two 'hot' lines and the neutral) from the power source. This ensures complete isolation and prevents phase imbalances, which is critical for many marine appliances and safety standards.
What chemicals is this product known to expose users to, according to California Proposition 65?
