My motor starter looks like one of the legs fried? One wire melted (first picture) and the terminal in the contactor melted (second and third picture) and it also blew my three phase breaker. My question is: What do you think the problem is? Is it just the motor starter? Pump motor? Who knows what the problem is? I guess I will know after I check the voltages and replace the contactor like Greg suggested.

More than likely the screw worked loose, or it wasn’t tightened securely to begin with. The damage was caused by heat at a weak connection.
