I have an “arc suppressor” that I need replaced. I am having no luck in finding this exact one, so I would like to know what the equivalent to this would be so I can order one. 
Thanks.
Hello @JRacek,
Thank you for your post.
I was not able to find anything in our system for that part, but using the NSKG-115 I was able to find a few places online that mention having them.
Would you mind sharing what you found, please?
Hi JRacek ,
I found a datasheet for the product here on page 19.
The most similar products that we carry are the following:
Note that all of these are slightly larger, physically, and although they are all rated for at least 600Vdc, which is higher than the Nissei part, their AC ratings are between 250Vac and 275Vac versus 350Vac for the Nissei part, so one would have to decide if any are compatible with your system.
Thanks for the info David.
I may have to try something.
David, I have two of these in use. So if I order a “different” one then what I have, do you think I would need them to be the same in order to work properly. Sorry my knowledge on these is very limited.
Hi JRacek,
Well, I’m afraid I really can’t say with any certainty whether any of these are actually suitable, as I know very little about your circuitry, how it operates, or the voltages involved, so this is just guess-work on my part here.
It looks like the two arc suppressors are for separate solenoids, so it wouldn’t seem to be necessary to have them match perfectly. If they were operating in parallel on the same circuit, then matching would probably be more important.
I don’t of this is any help at all.
But i found this?

Thank you for the find. 
mmoreno3086, turns out that it didn’t really help. Radwell lists it, but doesn’t have it.
Thanks David. We were lucky enough to find a lot of 5 on Ebay.

Good to hear you found a solution.
Best of luck!
