Blue Sea Systems 3000 Single Circuit ON-OFF Battery Switch, 600 Amp, Grey

The Blue Sea Systems 3000 is an HD-Series Single Circuit ON-OFF battery switch that connects a single battery to a single load group. It is built for marine electrical systems that need reliable, heavy-duty disconnect control at the helm or in the engine compartment. The switch carries a 600 Amp continuous current rating at up to 32 Volts DC and accepts two 4/0 AWG (95 mm2) battery cables using 1/2 inch terminal studs, making it suitable for high-current DC circuits found on larger boats.

Construction is a Grey plastic housing with copper contacts, mounted via a panel-mount rotary actuator with 2 positions (ON and OFF). The switch carries an IP66 waterproof rating and meets ISO 8846 marine switch standards, and it is ignition protected, meaning it is safe to install aboard gasoline powered boats without creating a spark ignition hazard around fuel vapors. It also meets ABYC (American Boat and Yacht Council) requirements for marine electrical installations.

This is the standard Single Circuit ON-OFF version without Alternator Field Disconnect (AFD). Blue Sea Systems also offers this same switch configuration with AFD as a separate model, which protects the alternator's diodes if the switch is turned to the OFF position while the engine is still running.
