Blue Sea Systems AA1-Series Circuit Breaker Toggle Switch

The Blue Sea Systems AA1-Series (A-Series) toggle circuit breaker combines a manual on/off switch and circuit protection in one device. It is a single-pole, magnetic-hydraulic breaker built for marine and other 12V DC electrical panels. It is the standard breaker used in Blue Sea Systems' electrical panels, so you can use it to add, replace, or upgrade a protected circuit.

Key Features:

• Meets American Boat and Yacht Council (ABYC) standards
• Combines switching and circuit protection into a single device
• Trip-free design: the breaker cannot be held ON during a fault current condition
• Magnetic-hydraulic circuit breaker type

Switch the circuit on and off with the toggle, and the breaker trips automatically to protect your wiring and equipment from overloads. Amperage rating, color, and other details vary by part number.
