Hi, Dave.

Where relay contacts arc like that (you didn't specify on make or on break) , the usual recommendation is for RC snubber networks. However, the design of those things is more art than science, or so it has always seemed to me.

I suggest you contact the relay manufacturer, explain the situation and see of they have any particular recommendations. If they don't, then from a purely shoot-from-the-hip standpoint, try starting with 100 ohms 2W in series with 0.1 F at 600V minimum connected across the offending contacts.

Good luck.
