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.

Effective Cabin Air Filter – Fresh and Clean Air for My Car
I recently replaced my car’s cabin air filter with the AC85111 activated carbon filter, and I’ve noticed a clear improvement in air quality inside the vehicle. It helps keep the cabin air fresh, especially during daily commutes and long drives. The activated carbon layer does a good job of reducing dust, odors, and outside pollution, making the driving experience more comfortable. I also noticed less smell from traffic fumes and general road dust entering the car. The fit was perfect for my Honda Pilot, and installation was simple without needing any special tools. It is compatible with several Honda and Acura models, which makes it a reliable replacement option. The material feels well-made and sturdy enough for regular use, ensuring consistent airflow while filtering out impurities effectively. Considering its performance and durability, it also offers good value for money. Overall, this is a practical, easy-to-install, and reliable cabin air filter that helps maintain cleaner and fresher air inside the car.

Good fit for our Honda Accord, quality filter
This was the perfect fit for my daughter's Honda Accord. It's a solid, budget‑friendly upgrade that fits perfectly. It only took a few minutes to install. The pleated material feels sturdy, and the activated carbon layer helps cut down on odors and everyday cabin dust.

No more funky smell!
Have had a funky smell for a while in my car. Air fresheners just couldn't quite cover it up. I pulled the old filter out which was reallll caked up with stuff and got the new one in. Not only is the funky smell finally gone, but the HVAC is a lot quieter when on full blast, and it blows the air harder. It fit great, installation was easy, and having the smell gone makes it worth absolutely every penny.
