Was this a problem? What would you like to do? Did you contact the manufacturer?
How do you know there was overvolt? Is the contactor designed to trip on overvoltage?

Yes it should trip after 2 to 4 second for 130 v , normal volt is 115v.
To avoid damage of load equipment while connected in overvoltage,
Overvoltage led alrady illuminated.

You know how much voltage the contactor is getting? How?

Also, minor point here, you have given us no information on the contactor, not even a model number so I have to ask, do you think that we are clairvoyant?

Help us out a little. What is the model number of the contactor and what is the device that is being controlled by the contactor?

Hey Don, Google says this is a portable gas generator...
If it ain't broke, don't fix it...

How could you know? The OP gave us little to go on...

I did a "quick" study of this generator. The specs say it will disconnect after a 125% overload... @ 120v, that's an overload of 30v... so it should disconnect at 150v, not 120v (115v would be 143.75v)
Check the specs again.

Its only 115V and it should trip at 130v according to manufacturer manual ,
Output contactor is 115 vdc.
