Default Main Disconnect

Hello all. I was at a home today and could not see a main disconnect...... However I did notice this one 60 Amp breaker that loops back and is soldered to the bus bar. Does this act as a main disconnect?

Google "Split bus panel". The top six breakers make up the service disconnect.

Split buss panel.
When all the 220 v breakers at the top of the panel are off, the panel is 'dead'.
The bottom 220v breaker on the left bank shuts off the lower section of 110v breakers.

Thanks! I have seen split bus panels before but they were a little more obvious where the split was. I appreciate you taking a look.

You mean 240v and 120v, right?
