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

Super fun for the dog, but doesn’t last.
Size: Small, Style: Bone, Product Packaging: Standard Packaging, Size: Small, Style: Bone, Product Packaging: Standard Packaging
I just ordered the 3 rd one. The bad thing is that my dog destroyed it in 3 hours. Luckily she spits out all the small pieces of plastic. The good thing is, that she gets so much joy out of it, it makes her so happy and tired that I am a fan! Well worth 9$! She is 25lb and I didn’t think she was an aggressive chewer before this toy. If your dog tends to eat all the plastic pieces , don’t get it.

See updated review; destroyed within 15 minutes
Size: Medium, Style: Bow Tie, Product Packaging: Standard Packaging
I'm bummed. My pup destroyed this within fifteen minutes. I thought because it was made by Kong, it would hold up a little better. I also have their black rubber toys and those are great! Update: I didn't expect to be contacted by the seller but they reached out after seeing my review and offered a full refund which I received quickly. Truly outstanding customer service!!!

Durable Chew Toy with a Fun Design
Size: Medium, Style: Bow Tie, Product Packaging: Standard Packaging
The KONG CoreStrength Bow Tie Bone is a playful and sturdy chew toy made to keep dogs busy. Its unique bow tie bone shape makes it easy for dogs to grab and carry, while the reinforced core is built to handle strong chewing. The textured surface not only adds interest but also helps clean teeth and gums during play. It’s tough enough for moderate to heavy chewers and works well for fetch, solo chewing, or tug games. While no toy is completely indestructible, this one holds up longer than many softer toys and gives dogs plenty of chewing satisfaction. Some very aggressive chewers may eventually wear it down, but most dogs will get a lot of use out of it. Pros: The reinforced core makes it more durable than average toys, the textured design supports dental health, and the shape adds variety and fun. Cons: Very heavy chewers may still break it down over time, the toy is fairly heavy for small breeds, and it isn’t designed to bounce or fly like other KONG toys. A strong and engaging chew toy that combines durability with a fun shape. It’s a smart choice for dogs who love to chew and play while also supporting healthier teeth and gums.

Best chew toy for GSD’s
Size: Medium, Style: Bone, Product Packaging: Standard Packaging, Size: Medium, Style: Bone, Product Packaging: Standard Packaging
One of my dogs has chewed through most chew toys for aggressive chewers with ease. This toy not only is still in one piece but still her favorite toy. We’ve gotten her many Kong toys and this one has definitely lasted the longest. She’s been chomping on it for about 2 years now and looks mostly whole.
