Hi all,
A new guy here.

I was building myself an air compressor, and after a trip to the local scrappy, I found myself a Embraco/Aspera NJ2192GK compressor in reasonable condition. However, as always - no electrics to go with it.

By reading the manufacturer's manual I see that a relay needed is 3ARR3B3AA3. But I am having horrible luck trying to find one, especially in the UK.
Is anyone aware of any equivalent or substitute? As you can probably see, I am not an expert in this field.

Using search I only found one thread for this particular compressor on an unrelated topic...

Your advice is sooooooo much appreciated!
