Simplify Your Dual Battery Management with the e-Series Dual Circuit Switch

Managing multiple battery banks in marine and automotive applications often involves complex wiring and multiple isolators. The Blue Sea Systems e-Series Dual Circuit Battery Switch solves this problem by allowing you to switch two isolated battery banks simultaneously with a single turn of the knob. This innovative design replaces the need for two separate switches, streamlining your dashboard or engine room layout while maintaining critical circuit separation.

Simultaneous Switching for Isolated Banks

Designed for dual-battery systems—typically a starting battery and a house battery—this switch ensures that both circuits are energized or disconnected at the same time. Crucially, it maintains isolation between the two banks. This means your sensitive electronics on the house circuit remain powered without risking the starting battery's charge, and engine starting spikes are kept away from your accessories. It offers a straightforward ON/OFF mechanism that simplifies operation for boat owners and vehicle operators.

Ignition Protected and Marine-Grade Durability

Safety is paramount in enclosed engine spaces and fuel lockers. This unit is ignition protected, making it safe for installation aboard gasoline-powered boats or vehicles where fuel vapours may be present. The case design allows for versatile mounting options, including surface or rear panel mounting, ensuring a clean installation regardless of your setup constraints.

High-Current Handling and robust Connections

Built to handle significant electrical loads, this switch features a continuous rating of 350A and a cranking rating of 700A per circuit (30 seconds). It is engineered with tinned copper studs for maximum conductivity and corrosion resistance, essential for harsh saltwater environments.

The terminals are designed to accept large cables required for high-current applications:

  • Terminal Stud Size: 3/8"-16 (Approx. M10)
  • Cable Compatibility: Accepts heavy-duty lugs for cable sizes up to 4/0 AWG (Approx. 120mm²)
  • Clearance: Generous 1.10" (27.94 mm) clearance for cable routing

*Note: Typical de-rating factors apply based on ambient temperature and cable sizing.

Versatile Voltage Compatibility

While often searched for as a 12V dual battery switch, this unit boasts a maximum voltage rating of 32V DC. This makes it perfectly suitable for both 12V and 24V systems commonly found in larger vessels, trucks, and off-grid 4WD setups. Whether you are refitting a yacht or upgrading a touring vehicle, this switch provides the reliability Blue Sea Systems is known for.

Key Features

  • Simultaneous Control: Switches two isolated battery banks with one simple knob.
  • High Amperage Rating: 350A continuous rating suitable for heavy loads.
  • Safety Certified: Ignition protected for safe use around fuel sources.
  • Flexible Mounting: Case design supports surface or rear panel installation.
  • Corrosion Resistant: Tinned copper studs ensure long-term electrical integrity.

Upgrade Your Power System Reliability

Ensure your battery system is safe, organized, and easy to operate. Install the Blue Sea e-Series Dual Circuit Switch today for a cleaner, more efficient power distribution setup.

Sleek, upscale and supremely comfortable
Size: 9, Color: Cognac
I did not know that Marc Joseph makes hands free slip ins. I own four pair of Skechers, and I thought they were the only game in town. I decided that I wanted a pair of business casual pair of wingtips. I already own two pair of Skechers Mark Nason wingtips in blue and black nubuck, so I bought a pair of their cognac colored. Perfectly fine shoes, but when they arrived, I didn't like the color, so the search was on! I found these cognac-colored Mark Joseph's and hands down, they fit the bill for what I was looking for! I actually bought two more pair of Skechers in the brown family in the same oxford, elastic lace style: One pair of another style of their Mark Nason line and one pair of their Garza line. So now I am comparing three pair of Skechers to the Marc Joseph's. Obsessive, I know :). Luckily, I have a Skechers store near me for easy returns. The look I was going for is a sleek, business casual that I could dress up or down. Three things that I love about the Marc Joseph's are the beautiful cognac finish: the white yet lower profile soles and the more formal, narrower toe style. The MJ's nailed it with the color. They have a slightly darker, more lustrous and glossier look than the others. The color alone looks classier and pairs well with black pants which I wear for work almost every day. The white soles are exactly what I was looking for. The visible rise is probably about a third of the thickness of the others and are a much more subtle, classier look. They offset the cognac color nicely but are not that in your face, sneaker looking, thick white sole. When I was comparing them to the others right out of the box, I thought they would be too narrow and tight because they looked sleeker and narrower than the others. But they fit perfectly and were very comfortable right out of the box. Upon closer inspection and comparison, I realized the narrower, sleeker look is because the eyelets for the elastic shoelaces are closer together that give the illusion that the shoe is narrower. They compensate for what might create a tighter fit across the top of your foot with two stretchy "gores" they are called on either side of the upper part. The "slits" are nicely finished, and you can't see the stretchy part and add a nice design touch to the shoe. But between them and the elastic shoelaces, they must stretch just enough to make them extremely comfortable across the top. So, if you have a high instep/arch, they should accommodate it nicely. Last but not least, they are very comfortable shoes. I wear a size 8 1/2 to 9 and my foot is slightly on the wide side. I bought the size 9's and they fit perfectly. If you are between sizes or have wider feet, you may want to size up a half size. Because the Skechers have much thicker soles, they might be slightly more cushioned, but the MJ's are cushioned more than enough for my purposes and very comfortable. Plus, they actually just feel better on my feet. I can't speak to how durable they will be as I just got them, but so far, so good. So, there you have it. I rely on other people's reviews a lot when buying online, and especially for shoes. I know it's always a crap shoot, particularly when buying shoes online, so I hope this review helps. Everybody's feet are different, but I highly recommend these.
