I have a Delta Q3, model #40-650, and I am in need of a new fuse. The fuse markings show it to be a 4 amp, but I would like to know if it's a fast-blow or a slow-blow. Factory was no help with specs, and when I plug in the fuse part number (1347417) into Google, it just gives suppliers, but no specs. TIA.

There was an old post on this forum about the Q3 and a club who has several. Maybe they can help you.

I found this information on fuses in general.
Blowing type. Fast-blow fuses will blow as soon as the current reaches the fuse's amperage rating, while slow-blow fuses are designed to tolerate a large number of startup surges and modest short-term overloads without blowing.
Fast-blow fuses usually have a thin wire while slow-blow fuses usually have a thicker, coiled wire.
You should never substitute a slow-blow fuse for a fast-blow fuse or vice versa.

From this information, fuse may have letter T or F on it. F-fast blow. T-slow. The picture of the fuse you need looks to be a slow blow.
Slow blow may also have a thin wire with what looks like a clump of solder on the wire.Larry Davis

Twenty years in electronics retail and here is a quick dirty way to tell the difference:
a fast blow will only have the wire element. Slow blow almost always has some extra structure that will be left behind after the fuse blows.
Secondly, there is a series of three letter engraved on one of the end caps and that can be matched.
Rule of thumb is that slow blow will not let go until it reaches 1.5 x the rating. It is to allow high draw items such as motors to come up to speed when the draw is stabilized.
While discussing blown fuses, on a fast fuse, if the wire just separates and the glass is clear, it's about 99% sure it was an overload. However, if the glass is smoked on the interior, chances are there was a short.Jim

Reply to Latest toy.by Jim FinnOur Hospitals also declined to receive toys in December .In fact they gave us back about 1200 of them that they had in storage. We found three new (to us) charitable groups to give them to. The pattern was given to me by a friend along with others. I have modified the pattern since and now have...

Reply to Spring Issueby will8989The fish puzzle is turning out to be a bit of a challenge. First I had to copy it. Which took sometime due to its size. Cut and taped together. No wood long or wide enough in my stock. Copied at 75%, cut and taped again and gave Bruce 2 boards to glue up. Hopefully, will be clear “sailing” on the...

Reply to Latest toy.by will8989That is really cute. You’re lucky you were able to give your toys away. Bruce’s club had to store everything. One of the hospitals finally called them for toys. They still have over 3,000 in storage....
