Blue Sea Systems E-Series On/Off Battery Switch

BLUE SEA SYSTEMS E-Series On/Off Battery Switch | Heavy-Duty Marine Power Control

Take command of your vessel´s electrical system with the BLUE SEA SYSTEMS E-Series On/Off Battery Switch, the industry standard for robust and reliable power management in marine and heavy-duty vehicle applications. Engineered for safety, durability, and performance, this switch provides a simple yet critical function: the ability to completely shut down DC power from the battery bank. This prevents parasitic battery drain during storage, provides a quick method for emergency shutdown, and simplifies servicing your electrical system. Ideal for boaters and vehicle outfitters who demand uncompromising quality, the E-Series switch is built to withstand the harshest marine environments.

The E-Series On/Off Battery Switch is designed to protect both your vessel and your valuable onboard equipment. Its high amperage ratings ensure it can handle the significant loads associated with engine starting and powering heavy-duty accessories, while its superior construction guarantees a long service life with minimal voltage drop.

Key Benefits:

* Enhanced Safety: Ignition protected and certified for use on gasoline-powered boats, this switch prevents the risk of explosion from fuel vapors. The included Alternator Field Disconnect (AFD) feature safeguards your alternator´s sensitive diodes from damage if the switch is accidentally turned off while the engine is running, saving you from costly repairs.
* Exceptional Durability: Built for the marine world, the switch features a case design rated to IP66, protecting it against powerful water jets from any direction. The tin-plated copper studs offer maximum electrical conductivity and superior corrosion resistance, ensuring a solid, reliable connection for years to come.
* High-Performance Power Handling: With a continuous rating of 350A and a cranking rating of up to 1000A, the E-Series is capable of managing demanding electrical loads, from engine starters to high-power inverters and windlasses, without overheating or failing.
* Flexible Installation: The versatile case design allows for surface, rear panel, or front panel mounting options. A removable isolating cover with snap-on sections protects the rear contacts and allows unobstructed wire access from any direction, simplifying the installation process.
