Battery Cut Off Switch

HI,
I have been searching the forum re: battery cutoff switches and found lots of info. But what I am really looking for is: Does anyone know what the maximum current draw is from the battery?

I want to make sure the switch I install is capable of handling the draw for my 3610 BH
Thanks

Even the cheapo switchs are rated @ 200 amps, I can't see your unit drawing over 50. If you have an inverter thats a differiant story. I have a 250 amp cutoff switch and run a 1500W inverter that can draw 40 amps.
