Could someone please advise on how I interprate the codes on this Varistor below.. I'm almost there, I can find the S14 / K140 on RS Components, But im unsure about the last 4 digits. RS Website PN:2508485459 The part I have is numbered 0023 Im unsure what this stands for. I have heard that it may be the manufacturing date, in which case the one I have found will be the correct item. I just want to be sure it isnt another rating variable of some kind.
The Varistor is from a 110v Honeywell DKO 972 Flame Control unit from an EOGB X500 oil Burner.
Could someone just give me the nod as to if I have found the correct part and that I only need the S14 K140 part of the code. Thanks in advance. Roy
