Hi Miami Guy,
Without much looking about, I figure you have a Sprecher + Schuh CT7-45-45 Thermal Overload Relay or the like. It is there to protect the electric motor on your compressor if it does not start rotating when powered on. The problem with the type of AC motor on your compressor is that the current to run/start the motor is close to what is called the locked rotor current. A simple fuse will not protect the motor. That is where the overload relay comes in. It only allows the high current for a period of time before it opens the circuit (thus protecting the motor from burn-out). Very, very nice job was done on setting up that compressor. A professional rig for sure. Remember to use the correct synthetic oil in that puppy. Bauer OIL-0024 is the right stuff IIRC.
If you take care of that unit the biggest problem you will have is not getting to use it enough
Enjoy,
Nugria
