Slow blow fuse4/2/2023 But when sold as individuals, the "H" and "M" are dropped. Need complete part number to get to current ones such as 312008.HXP for fast glass, 8 amp, RoHS compliant (XP suffix), box of 100 (H in suffix). I'm sure that just putting a regular fuse in that spot is fine, just wondering why it is specifically different.ģ12008's are still made - I buy boxes of 312 series fuses pretty much every month. It always has a specific 8A 32V NB fuse called for in that spot. On the Williams Fuse chart is calls for all FB and SB fuses except for one spot. I'm just wondering why every machine I have seen, comes with those flat blade fuses in that slot and not anywhere else on the board. The Busmann AGC-8 looks to be just a standard FB fuse you can get anywhere. The 312008 is obsolete and NLA and was just a FB fuse without the flat blade inside. I would say that to do so would create more confusion with people asking questions rather than simply laying down the law in the manual. So then you might ask why didn't Williams update the docs to allow for a range of choices? Good question. If someone knows the history and timeline of glass cartridge fuses please chime in! I would guess to eliminate confusion they specified 8A, 32V NB fuses starting with JD because that's what ops had stocks of on hand and perhaps at the time you started seeing higher voltage rated fuses in the FB variety. I would say this is one of the defining features of a fast acting fuse.Īnd since not all fuse values came in all types and sizes, Williams fuse selection reflected that. It also distinguishes between "fast acting" and a "glass tube" fuse in the 1/4" x 1 1/4" size where the fast acting will open at 200% load in 5 seconds or less. If you look at this old Bussmann catalog that John Robertson posted - you will notice that not all fuse values come in all types. Then when Williams switched to WPC-95 they went to all 5x20mm time delay (slow blow) fuses with everything being rated at 250V. This only continued until the last DCS game, Popeye. Specifically on the DMD controller and F115 they went from SB to FB fuses while keeping the fuse ratings the same. They also changed fuse types in other places with this game. It isn't until you get specifically to JD (DCS, Aug 1993) where Williams specified "8A 32V NB" at F114. This is the same for TAF (WPC Fliptronics 1.) TZ (Fliptronics 2) is also the same except the line filter where it only says "8A" for domestic and "5A SB" for foreign. Party Zone (WPC DM) did the same but interestingly specified an 8A NB for domestic game line filter and 4A SB for a foreign game. If you look at the manuals for the fuse charts in WPC games, Funhouse (WPC A/N) specified "8A NB" at F114, and SB everywhere else.
