5511e - e-Series Dual Circuit Plus™ Battery Switch

An industry standard compact battery switch just got better

Blue Sea Systems e-Series Dual Circuit Plus switches isolate your Start and House battery circuits, preventing accidental discharge of the starting bank and protecting your electronics from engine starting sags and spikes.

Ideal when combined with an Automatic Charging Relay, which will automate charging while the Dual Circuit Plus will simplify the switching. In an emergency, this switch allows you to combine two battery banks in the ON position. The combine feature allows you to cross-connect your battery banks to start the engine or make a radio call.

Capable of 350 Amperes continuous rating per circuit, these switches have a total current-carrying capacity of 1000 Amperes. And, because they are UL Listed, you can be confident that they safely handle these high amperages. Ignition-protected, safe for use aboard gas-powered boats, and meets  ABYC battery switch standards. Long 7/8" studs accept up to 4/0 cables.

Because these studs are cast into the body of the switch, they will accept the high torque loads required to create a secure connection that minimizes resistance. Case design allows surface or rear panel mounting and fits all Perko and Guest low amperage battery switch hole patterns. Tactile textures on the face for knob position awareness by feel only.
