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

Keeps the wee wee pads securely snapped in so puppy won't run away and play with them
Size: Small
My maltese puppy would run away and play with the wee wee pads if they weren't secreted inside a holder like this that straps them down. He uses the wee wee pads in this holder very well. I would give this five stars, but my puppy likes another kind of wee wee pad holder that has a plastic grate over it just a tiny bit more. I bought two different kinds of wee wee pad holders to keep at different locations to see what he liked to use. He uses both, but prefers the grated one just a little more. Even so, this is a quality wee wee pad holder and the pads snap in so easily and securely. Great purchase.

PAWISE Pee Pad Holder * Big size *
Size: Small
You GUYS.....they shipped this damn thing in a 65inch TV box Do the measurements and then think about how big a that damn tv box is....literally it arrived and my husband & kids thought 1000% I bought a new TV. So far the product I am happy with / its a bigger square for those dancing pups. I am using this on a Chorkie puppy. The big pads fit and it latches them. Now the pup has realized he can pop the latches but he cant get the pad cause the lid is ontop . Im sure this is a puppy thing and will pass he got redirected and hasnt messed with it since. day 2 of use. *** THANKS JEFF & employees for the huge ass waste of cardboard LOL **

Perfect for puppy!
Size: Small
I got this because I bought another (cheaper) alternative and the pads were shredded within the hour. This holder has the corners of the pad covered and that was the saving grace. Worth the extra money because you aren’t wasting money on puppy pads that are shredded before they are even used. If your puppy is still set on shredding, make sure to add lots of toys on a rotation (never the same toys everyday) and it helps a lot. Once I did that and changed the holder, no shredded puppy pads!

Misleading size stated in adv.
Size: Small, Size: Small
Absolutely ridiculous! Says 23.5” by 23.5 “. It just barely measures a little more than 19 inches. You have to fold up the 24” by 24” per pad to fit it. I don’t know if my 5 pound chihuahua will be able to use it. A complete waste of money!! First photo shows it in frame - 2nd photo show what is a 24 by 24 pad.
