As @KingDarBoja said there are lots available: some suggestions:
type relay in to the fritzing parts search box and press enter (the search box is the magnifying glass in the parts bin). A number of different relays in core parts come up.
Search here in the forums. A number of different types or relays have been posted in parts submit that have not made it in to core parts yet.
if you need a specific model of relay try a google search with the search term “fritzing part relay_model” (where relay model is replaced by the part number of the relay you want).
