Hi there,

I am looking a manual/help on how to set the P&B Gold relay ( For three phase indution motors), 20 Minute Type MN4A. I am aware that the relay is completely ancient; however we are still using it in our operation.

Thanks in advance.

There is a link to a P&B Golds manual ( didn't work for me) so you likely have to contact them. The info is on their website.
