In my quest for fuses & disconnects, for my RV system I came upon this breaker:
http://cgi.ebay.com/CIRCUIT-BREAKER-300-AMP-12V-SELF-TEST-new-PS82-300A_W0QQitemZ140242285164QQihZ004QQcategoryZ32809QQtcZphotoQQcmdZViewItemQQ_trksidZp1713.m153.l1262

I was looking for a 300 amp fuse between my inverter and battery bank. Is there some reason that this breaker would not work. I think its primary function is for car audio, but it is rated for 300 amps & 12v.

    The self-reset might worry me.

    Good point, I'll send them an e-mail and ask the question. I assumed it was a self test, (the button to trip the breaker) and a manual reset (the lever to reset the breaker).
