Description

Experience superior power management and enhanced safety for your marine or automotive electrical systems with the BLUE SEA SYSTEMS M Series Dual Circuit Plus. As a leader in the Electronics and Chargers category, this robust switch is engineered to provide complete and simplified control over dual battery banks, ensuring reliability when you need it most. It is the ideal solution for boaters, RV owners, and anyone operating with a critical dual battery setup, offering both isolation and emergency combining capabilities in one compact unit.
The primary function of the M Series Dual Circuit Plus is to manage two separate battery circuits, such as an engine starting battery and a house battery, from a single, easy-to-use switch. This design protects your starting battery from being depleted by auxiliary loads, so you always have the power to start your engine. For ultimate flexibility and safety, this switch simultaneously switches two isolated battery banks or combines battery banks to all loads. This functionality is enhanced by its innovative Make before break contact design, which allows switching between battery banks without power interruption. This critical feature ensures that your sensitive electronics, like GPS, fishfinders, and stereos, are safeguarded from voltage spikes or data loss that can occur when power is cut and restored.
Engineered for the demanding conditions of marine and off-grid environments, the M Series Dual Circuit Plus boasts a rugged build and intuitive operation. Its ignition-protected design makes it safe for installation in the engine compartments of gasoline-powered vessels. The bright, easy-to-read labels and tactile feel of the switch provide confident operation, even in challenging conditions. By consolidating the control of your house and starting circuits into a single point, you simplify your dashboard and streamline your power management procedures, giving you more time to enjoy your time on the water or the road. Gain peace of mind knowing you have a reliable method to combine your battery banks for an emergency start, a feature that can be invaluable if your primary starting battery becomes drained.
