880865 2010-04-29 02:50:00 Hello in Upsidedown Land - is there a difference between a S4A and a T4A fuse?

I think they're both the same, maybe different manufacturers, but I also feel they are both Slo-Blow type - NO?

If S = Slo-Blow then it makes sense they are the same, but I don't know for sure.

These guys think it may be from German:

It may even have something to do with what shape the fuse is.

880867 2010-04-29 03:18:00 S and T fuses are heavy duty time delay fuses and used for circuits having critical or high motor loads or circuits having motors that cycle on and off often (e.g. a sump pump). These fuses have a longer time delay feature than the TL or SL fuses. However, just like the TL and SL fuses, the only difference between the "T" and the "S" fuses are the types of bases. The "T" fuse uses an Edison base and the "S" fuse uses a Rejection base.

These fuses work by use of a spring loaded metal fuse link attached to a solder plug. If the overloaded circuit condition continues for too long, the solder plug melts and the spring pulls the fuse link free, cutting power to the circuit. This allows the fuse to absorb a longer temporary circuit overload.
