DESCRIPTION
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
