CR730-A-24 identification
It appears to be a relay used in PIR lamps.



source - P29

The diagram appears to be an application where a set of three lights can be switched on by any of three switches or relays. I would guess that PR1 and PR2 are two PIR detector units at separate locations and that wylacznik is a manual switch.  I don't think you can deduce anything about the CR730-A-24 relay from that diagram.
