Alternator Breaker

[TroyMaynor@aol.com]

Hi Again,
I have notice some have used an a.c. breaker on the panel instead of the 30 
amp slow blow fuse inder the cowl. I have a 35 amp a.c. breaker that I bought 
at the swap meet at Sun n Fun a few years ago. The following information is 
printed on the side. 35A a.c.
S-1360-35
MP-1600Y-35
Mechanical Products

Is this an aircraft breaker or for industrial or either? Does anyone have any 
idea if this is ok to use for the alternator? 
Thanks,
Troy
