Blue Sea Systems 6011 m-Series Dual Circuit Plus Battery Switch, Red

The Blue Sea Systems 6011 m-Series Dual Circuit Plus Battery Switch is a compact marine battery switch built to manage two separate battery banks from a single control point. Unlike a basic single-circuit switch, the Dual Circuit Plus design switches both battery banks simultaneously while keeping the two banks electrically isolated from each other, so each bank stays dedicated to its own circuit during normal operation. In an emergency, such as a low or dead start battery, the switch can combine the two banks to provide extra cranking power or to run essential equipment. The make-before-break contact design changes between positions without interrupting power flow, which helps protect sensitive electronics from voltage spikes during switching.

Installation is flexible, with three mounting options: surface mount, flush mount, or rear-of-panel mount, allowing it to fit a variety of helm and engine room layouts. Ignition protection is built in, making the switch suitable for installation in the engine room of gasoline-powered boats. The switch face has a tactile surface and a removable knob, which helps with operation in low light and lets you lock out the switch to prevent unintended power flow while servicing the electrical system. Terminal studs are tin-plated copper, formed as a single piece with enough length to accept multiple cable connections and provide a secure fastening point. The housing carries an IP66 rating, meaning it is protected against powerful water jets, an important consideration for equipment mounted in an open engine room or exposed helm station.

Frequently Asked Questions

What does the Dual Circuit Plus design do differently from a standard battery switch? The Blue Sea Systems 6011 switches two battery banks simultaneously while keeping the two banks electrically isolated from each other, rather than simply connecting one battery to one load group. It also includes a combine feature to draw power from both banks together when needed, such as for engine starting or running essential equipment off a low battery.

Can I combine both battery banks if one battery is low? Yes. The 6011 battery switch lets you combine two battery banks in the event of a low start battery, providing extra power for starting the engine or running critical equipment before returning to isolated operation.

Is this switch safe to install in a gasoline engine compartment? Yes, the Blue Sea Systems 6011 includes ignition protection, so it is suitable for installation in the engine room of gasoline-powered boats.

How is the 6011 switch rated for water and moisture exposure? It carries an IP66 rating, meaning the housing is protected against powerful water jets, which is useful for switches mounted in open engine rooms or exposed helm areas.

What mounting options are available for this switch? The 6011 Dual Circuit Plus switch can be installed three ways: surface mounted, flush mounted, or mounted at the rear of a panel, giving flexibility for different helm and engine room layouts.

What is the current and voltage rating of the Blue Sea Systems 6011? The 6011 is rated for 300 Amps at 32 Volts, with a maximum wattage rating of 9600 watts, and operates in an ON-OFF, 3-position configuration.

What are the terminal studs made of? The switch uses tin-plated copper terminal studs built as a single piece, with sufficient length to connect multiple cables while maintaining a secure fastening point.

Does the switch have a contact design that avoids power interruption? Yes, the 6011 uses a make-before-break contact design, which switches between battery banks without interrupting power flow, helping protect connected electronics during switching.

What are the physical dimensions and weight of this battery switch? The Blue Sea Systems 6011 measures 7 x 4 x 3 inches and weighs 0.8 pounds.

Can the knob be removed to prevent someone from switching the battery banks? Yes, the 6011 has a removable knob, which can be taken off to help prevent unintended power flow while servicing the electrical system, along with a tactile switch face for use in low light.

What color does this switch come in? The Blue Sea Systems 6011 m-Series Dual Circuit Plus Battery Switch is finished in red.

Is the 6011 switch part of a larger charging system? The 6011 Dual Circuit Plus switch is designed to work alongside an automatic charging relay, which automatically combines battery banks for charging and isolates them again during discharge, giving a complete two-battery-bank management setup.
