Simplify Marine Power Management with the e-Series Dual Circuit Plus

Managing multiple battery banks on a vessel often involves complex wiring or the risk of draining your starting battery through house loads. The Blue Sea e-Series Dual Circuit Plus Battery Switch offers a sophisticated solution by simultaneously switching two isolated battery banks with a single ON/OFF knob. This intuitive design ensures that your engine starting battery remains isolated from your house battery circuit, preserving critical cranking power while protecting sensitive electronics from voltage spikes during engine starting.

Simultaneous Switching and Isolation

Unlike traditional selector switches that force you to choose between batteries, the Dual Circuit Plus acts as two switches in one. When turned to the ON position, it connects the start battery to the engine and the house battery to the distribution panel simultaneously, yet keeps the circuits electrically separate. This isolation is crucial for modern boating; it allows you to run refrigerators, lighting, and audio systems from the house bank without the risk of depleting the battery required to start the engine. It effectively solves the common problem of accidental starting battery discharge while at anchor.

Emergency Parallel Functionality

Safety and redundancy are paramount in marine environments. In the event of a flat starting battery, this switch features a "Combine Batteries" position. By rotating the knob to this setting, you can parallel both battery banks, utilising the capacity of the house bank to provide the necessary amperage to start the engine. This built-in emergency cross-over eliminates the need for jumper cables or separate emergency parallel solenoids, providing immediate peace of mind when you are far from shore.

Engineered for Harsh Marine Environments

Built to withstand the rigours of the ocean, the e-Series switch features tinned copper studs for maximum conductivity and corrosion resistance. The 3/8"-16 (Approx. M10) terminal studs are designed to accept heavy-duty ring terminals, accommodating cables up to 4/0 AWG (Approx. 120mm²). The switch is rated for a continuous current of 350A per circuit, making it suitable for most small to medium-sized outboards and inboard engines.

Additionally, the unit is ignition protected, making it safe for installation in the engine rooms of petrol-powered boats. This safety rating ensures the switch will not ignite flammable fumes, a critical requirement for compliance and safety on board.

Make-Before-Break Design

The internal mechanism utilises a make-before-break contact design. This allows you to switch between the "ON" and "COMBINE" positions without momentarily cutting power, ensuring that GPS units, radios, and other sensitive electronics do not reboot or lose signal during critical switching operations.

Key Features

  • Dual Circuit Plus Design: Switches two battery banks simultaneously while maintaining isolation
  • Emergency Combine: Parallels banks to start the engine if the starting battery is low
  • High Current Rating: Handles 350A continuous current per circuit suitable for substantial loads
  • Ignition Protected: Safe for installation aboard petrol-powered vessels
  • Corrosion Resistant: Tinned copper 3/8"-16 (Approx. M10) studs ensure long-lasting electrical connections
  • Make-Before-Break Contact: Allows switching without interrupting power to electronics
  • Versatile Mounting: Case design supports surface or rear panel installation

Amazing!
Color: Mermaid
I bought this for my musical Seussical and for everyday use. I was very impressed by the quality it was so easy to put on and it washed right off. This is the perfect glitter! I tested it on my arm face and hair it and my 2 only problems are that the color is not what it looks in the picture I got the mermaid color thinking it would have more pink but it does not have much pink in it when you put it on it appears more blue and green. The other thing is for those who got this for their hair be ware the glitter will fall off I didn’t get to give it a great chance on my hair but I think it’s not terrible you just need to give it more time to dry than I did or whenever you move you’re head glitter will come off. Overall I think this is an amazing product and I am definitely considering trying other colors.

Pretty and easy to use/wash off
Color: Sparkling Pink
Pretttyyy! It washes off easily when you want it to, so there’s no worries with it feeling “permanent.” It does rub off too but with excessive rubbing. It’s a pretty color that’s holographic-like. We love it for sparkly cheeks!

Great Body Glitter
Color: Sparkling Pink
The main colors of this holo glitter are purple, blue, and silver. It worked perfectly for my outfit, and I honestly had no complaints. When it comes to glitter, there’s nothing you can do to prevent it from getting everywhere, so I don’t hold that against the product at all. It sheds like normal but this literally stayed on after I wore it all day/night at a concert while sweating in 90-100°F heat the whole time; it lasts great. It also washed off super easy with some warm water and soap, which was such a relief. The gel/liquid itself is incredibly easy to apply, as it is pretty thin and dries quickly (maybe 3-5 minutes for total dryness I think?). You have to shake the bottle a bit to get the glitter spread out, but it rolls on easily. It sparkles great as well.

Cheap body glitter if that is what you are looking for
Color: Laser Green
The container broke so be careful!!! Also, the glitter doesn’t really roll on that well and kept getting clumped into the sides of the roller. If you are looking for cheap body glitter this is it!! Otherwise, it lasts all day and washes off easily
