Siemens makes a power relay model #3TG1001-0BB4 that has a toggle switch on the front...looks like 1 or 0... I am assuming power on and off...would that be correct? Why would it have an on or off...could this switch mean
something else?

The link to view the relay on page 30 of 32 of the link.:

It looks like a flag to visually indicate when the relay has pulled in.

Could be a manual on off for troubleshooting. Use care if induction load connected. May flash on you if turned to on and load is bad or shorted.
I could not find the exact relay with your part #. I don't read German.

I downloaded the detailed sheet and still can't tell. I believe it's an integrated overload protection breaker.

It is listed (in english) on page 30 of the pdf document provided by the link from "cinner".

No overload protection, just simply a relay/contactor with a visual indicator to indicate whether it is "picked up" or not.
The small tab can be used to manually "pick up" the contactor but is not intended for this purpose.
