Bussmann S-3/10 – Frequently Asked Questions

1) Will a Bussmann S-3/10 plug fuse screw into a standard Edison plug fuse socket?
No. The S-3/10 is a Type S rejection base fuse, so it will not thread directly into a plain Edison (Type T/W) fuseholder. It needs the matching Type S adapter for its amperage installed in the socket first. That is the whole point of the rejection design: once the adapter is in, only a fuse of the correct rating will fit, so nobody can swap in a heavier fuse later.
2) Why choose a time delay fuse over a fast acting one for a motor circuit?
A time delay fuse rides through the brief inrush a motor, transformer, or compressor draws at startup and only opens on a sustained overload or a short. A fast acting fuse of the same rating would nuisance blow every time the load started. The S-3/10 is built as a time delay element, which is why it suits motor control and HVAC control circuits rather than purely resistive loads.
3) What fault current can the Bussmann S-3/10 safely interrupt?
It is rated 10 kAIC, meaning it can clear a fault of up to 10,000 amperes without rupturing. That matters when the available fault current at your panel is specified on the drawing or the label, since the protective device has to equal or exceed it. For a small control circuit fed from a residential or light commercial service, 10 kAIC is normally more than enough headroom.
4) Can I put a higher amperage Type S fuse in the same socket later if this one keeps blowing?
Not without changing the adapter. The rejection base is sized to the amp rating, so once the 3/10A adapter is installed only a fuse of that class will thread in. If the fuse keeps opening, the circuit is drawing more than 0.3 amps and the load needs investigating, not the fuse upsizing. Upsizing means pulling the adapter and re-evaluating what the conductors and the equipment are rated for.
5) Is the base of this plug fuse metal or insulated?
The S-3/10 uses a plastic base with the threaded shell for contact. The plastic body keeps the current carrying parts insulated from your fingers while you are turning the fuse into a live fuseholder.
6) How does the Bussmann S-3/10 come packaged for stocking on a service truck?
It ships in a blister pack, which keeps the fuse identifiable on a shelf or in a van bin rather than loose in a drawer. Handy if you are carrying several Type S ratings and need to grab the right one fast.
