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).
