How hot should this relay get?......

I'm attempting to diagnose some electrical problems on the car, and
noticed that the electric window relay gets very hot after the
car has been running a while. (1/2 hour) It is too hot to touch.

Is this normal?

This relay is located right behind the instrument cluster.

Has anyone else noticed this relay gets too hot to touch
