Product Description

11003 HD-Series Heavy Duty 3 Position Selector Battery Switch with AFD


Switches isolated battery banks to all loads.

  • Includes AFD (Alternator Field Disconnect)
  • Ignition protected—safe for installation aboard gasoline powered boats
  • Case design allows surface or rear panel mounting
  • Accepts two 4/0 AWG (95mm²) battery cables

Blue Sea HD series boasts our highest continuous current rating (500A), and massive 1600A 30s cranking rating.  Larger than our M-Series, these specialized battery switches are used where huge current draws are possible.

The 11003 is an OFF-1-2 switch.  It does NOT have a BOTH function.  This is basically a true A-B switch, where one load can be switched OFF, or from two different sources (but not both sources).
