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.

They were cute and stayed on for days!
Color: Set B:3 gold+3 silver
These face sparkle tattoos are great! If you apply them right, they can last several days. My first try, I got the entire tattoo wet all at once. It slid around and it ended up crooked. And because I couldn’t apply pressure to the entire area, some of the spots came off fairly easy. My second attempt was much better. I started on my nose area and then did one cheek at a time, holding it firmly in place the entire time. It was straight and everything stayed on until days later whenI used makeup remover to take it off. I really love these. I wore them for the holidays and felt fun and festive. I WILL buy them again!

Worth it!
Color: Set D:6 holographic multicolor
Great product. Great price. Used for myself and a friend for her first 5k race. I also let me 3yr old daughter wear some for her 1 mile fun run. They lasted throughout the day/race. My recommendation if you buy. Cut the single piece into 3 separate. Nose, one for each side and apply in 3 separate sections. It takes a touch longer BUT it is easier to apply. Especially if your face is smaller and it’s easier to handle.

Rave Freckles!
Color: Set D:6 holographic multicolor
I got these for a Rave. They were very cute once I figured out the best way to put them on. I had to go through 2 before I figured it out. They stayed on well (as well as any temp tattoo can). If you have trouble getting them off, just get some facial oil cleanser! They were cute and I got lots of compliments.

Easy application
Color: Set D:6 holographic multicolor
Lasts all day. Is a bit sticky to the touch once applied (which actually helps keep my glasses from slipping). Fairly easy to remove with some oil and a cloth, didn't try removal wipes that come with them.
