Hello, can you send me a few photo's of the old contactor taken from different angles? Use the paper clip icon at the right end of the tool bar above or the attach files link to the left of your send button.

We can go from there

Go to Grainger industrial supply or Johnstone Supply and ask for the following:

"General electric 24volt coil, 230 volt, two pole, 40 amp contactor." when they bring it to inspect it, it should be identical to what you have.

Or you can order it online at

Its time to locate the 'Finish and Rate your expert' link, follow the prompts, it is how the company pays me for my time. In exchange I will hold the question open for any follow up you might need, Thanks!
