Blue Sea 300A Red Mini m-Series 3 Position (OFF/1/2) Battery Selector Switch
Blue Sea 300A Red Mini m-Series 3 Position (OFF/1/2) Battery Selector Switch
Compact red Off, 1 or 2 battery selection for high-current DC battery management in marine and mobile systems.

DESCRIPTION
Blue Sea m-Series 3 Position Battery Selector Switch
The Blue Sea m-Series 3 Position Battery Selector Switch is a compact, high-current DC battery switch designed for selecting between two isolated battery inputs and an off position. With its red knob, clear Off, 1 and 2 operation, and 300A continuous current rating, it is well suited to marine, RV, 4WD canopy, service vehicle and compact auxiliary battery installations where a robust manual selector is preferred.
This model is the Blue Sea 6008, a red selector switch from the m-Series manual battery switch range. It provides three switch positions, two battery inputs and no battery combine function, making it suitable where the requirement is to choose battery bank 1 or battery bank 2 to supply loads rather than paralleling both banks.
Built for High-Current DC Battery Switching
The 6008 is rated for a maximum voltage of 32V DC and has a 300A continuous rating, 500A intermittent rating for 5 minutes, and 900A starting rating for 30 seconds. That current capacity makes it a practical choice for many low-voltage DC systems using suitably sized cabling and correctly rated circuit protection.
Blue Sea specifies tin-plated copper terminal studs for conductivity and corrosion resistance. The 3/8 in - 16 studs suit M10 ring terminals, and the one-piece terminal stud design is intended to remain secure over time. Cable size to meet the stated ratings is 4/0 AWG, with terminal stud torque specified at 120 in-lb, or 13.56 Nm.
- Three-position selector: Off, battery input 1 or battery input 2 operation for straightforward manual battery selection.
- 300A continuous rating: Supports demanding DC battery switching applications when installed with cable sized to the rating.
- 32V DC maximum: Suitable for common 12V and 24V DC battery systems within the manufacturer’s voltage limit.
- Ignition protected: Manufacturer states it is safe for installation aboard gasoline powered boats.
- Flexible mounting: Case design allows surface or rear panel mounting.
Compact m-Series Design
The m-Series format is designed to provide a compact switch footprint without stepping down to a light-duty battery isolator. Blue Sea states the case design allows surface or rear panel mounting, helping installers place the selector switch in battery compartments, electrical lockers, switch panels or other controlled mounting locations where access and cable routing are considered during system design.
The isolating rear cover design helps protect rear contacts and allows wire access from different directions. This is useful in tight installations where large battery cables need to be routed cleanly without excessive bend stress. Mounting holes accept #10 screws, and the manufacturer lists cable clearance for 4/0 AWG cables as 1.12 in, or 28.45 mm.
For Marine and Mobile Battery Management
This switch is intended for manual battery management rather than automatic charging or voltage sensing. It suits applications where the operator needs a simple, physical battery selector for DC loads. In marine installations, it can form part of a properly designed battery switching system using the latest applicable standards, appropriately rated cabling, terminals, fusing and installation practices.
Manufacturer instructions state that positive battery power should be disconnected before installation, appliances should be turned off before turning the battery switch to OFF, and the switch should not be turned to OFF while the engine is running. Correct installation is important for high-current DC systems, especially where alternators, starter motors, charge sources and battery banks are involved.
Choose the Blue Sea 6008 for a compact, clearly labelled red battery selector switch that provides dependable manual Off, 1 or 2 control for well-planned DC battery systems.
