3-way Guest Battery Switch

[rgleason]

Our 34 year old 3-way Guest Battery Switch froze in the Batt 1 position after long operation of the Yanmar 3YM30 Diesel engine. I was able to free it turning it the other way, but the contactors were no longer working right and the panel was powered at unexpected positions. I decided to disconnect the power at the batteries leaving the bilge pumps powered, and get a new 3-way.


Is the Marinco Guest 2110A with Alternator Field Disconnect the appropriate replacement? With 345a momentary and 230a continuous rating?


Actually I think the 2100 with Alternator Field Disconnect is the one, with the same ratings.

My understanding is the Blue Sea versions are more robust.

Yes, that is correct, John. They have considerably higher ratings. I ended up getting the Guest in hopes that the installation will be easier. Thanks for your response.

A 345a momentary and 230a continuous rating will be fine for your application.

Thank you Wotname.
