The Blue Sea Systems A-Series White Toggle Circuit Breakers are the marine industry standard for dependable circuit protection and switching. Designed to meet ABYC standards, these breakers combine switching and circuit protection into a single compact device — ideal for use in Blue Sea Systems electrical panels and other onboard applications.
Each breaker features a magnetic-hydraulic, trip-free design, meaning the toggle cannot be held “ON” during a fault condition. Built with corrosion-resistant stainless steel hardware and a white toggle actuator, these breakers are purpose-built for harsh marine environments and extended service life.
Available in a range of amperages from 5A to 50A, the A-Series offers consistent performance for both AC (240V) and DC (32V) systems.
