The Blue Sea Systems m-Series Dual Circuit Plus 8689 is a comprehensive electrical management solution designed specifically for twin engine configurations and complex power systems. This system features a 100A C-Series Flat Rocker Circuit Breaker and three 15A Push Button Thermal Circuit Breakers, providing reliable 24-hour circuit protection in demanding environments. Its advanced design safeguards electronics from voltage sags and spikes caused by engine cranking, ensuring consistent performance and longevity of your electrical components. The system allows for an emergency cross connect between isolated battery banks, facilitating quick power redistribution during critical situations, while also isolating the engine circuit from the house circuit to prevent unintended power flow. Simplified battery switch operation combined with the ability for independent battery discharge makes managing multiple power sources straightforward and efficient. An integrated Automatic Charging Relay automates the charging process for both batteries, maintaining optimal charge levels and reducing maintenance needs. Included labels enhance system clarity, with 4218 square format labels and 4140 round labels for 24-hour monitoring. This product is engineered to enhance safety, reliability, and operational convenience, making it an essential component for marine, RV, and other vehicle electrical systems where dual battery management is critical. Please note the product contains chemicals known to the State of California to cause reproductive harm, and additional information is available at P65Warnings.ca.gov. For detailed installation instructions, consult the owner’s manual available online.
