The Blue Sea Systems 7427 A-Series circuit breaker provides reliable 10-amp overcurrent protection for DC electrical systems in marine, RV, and automotive applications. This single pole, magnetic hydraulic circuit breaker features a compact small case design that fits standard 2-inch panel slots, making it ideal for retrofits and new installations.

Key Features:

• 10-amp rating with trip-free magnetic hydraulic mechanism
• Flat rocker actuator with color indicator showing OFF position
• Trip-free design prevents breaker from being held ON during fault conditions
• Single pole configuration for individual circuit protection
• Restricted-off function for enhanced safety control
• Rated for 250 Volts AC / 80 Volts DC maximum
• 10,000 switch cycles at rated amperage and voltage
• Compact 2-inch slot mounting footprint

The A-Series breakers from Blue Sea Systems combine professional-grade circuit protection with intuitive visual status indication. The magnetic hydraulic trip mechanism provides precise overcurrent protection without thermal drift, ensuring consistent performance across varying ambient temperatures. The trip-free design is a critical safety feature that automatically trips the breaker during overload conditions, even if the actuator is manually held in the ON position.
