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.

Amazing Quality & Price
Color: Black Band and Blue Face, Color: Black Band and Blue Face
Exactly as described. It looks absolutely stunning in person. It's very lightweight. Adjustable metal band with tool for ejecting the pins and band pieces. Movement around my wrist feels great and not pinching my arm hairs. Extremely easy to use and set up. Fits perfectly after making some minor adjustments on the band. Battery life promise of 10 years.

Not bad for a watch under 50 bucks
Color: G2856-all silver, Color: G2856-all silver
Im not sure what material this watch is made of but the band doesn’t sound weird, it doesn’t feel like a very solid watch but it really looks fancy and nice i really like it a lot,plus lets be realistic you can have high expectations for 40 bucks, is the first one I bought from this brand, I would like to buy yhe automatic one that is around 150 but i want to try the cheapest one first and see if i like it or not, so far im happy i will update in some time to see how’s holding up
