Bussmann TPS-B-30 – Frequently Asked Questions
1) Can the Bussmann TPS-B-30 fuse be used on an AC circuit?
No. The TPS-B-30 carries a DC-only rating of 170 Vdc, so it belongs in DC power distribution, telecom rectifier, and battery backup circuits. There is no AC voltage rating behind it, so don't drop it into an AC branch circuit and assume it will clear the fault.
2) Will a 30A TPS fuse fit my existing fuse holder, and what size is the body?
The TPS-B-30 body measures 0.56 x 0.56 x 0.87 inches with silver-plated brass ferrules at the ends. Measure your holder clips against those numbers before ordering, since the ferrule type and that compact body are what decide whether it seats in a telecom power panel block.
3) Is the TPS-B-30 rated for a high fault-current central office panel?
Yes, it is a current-limiting fuse with a 100 kAIC interrupting rating, which is what lets it be applied on DC buses fed by large battery strings and rectifiers in central office and data center power panels. Current-limiting operation also holds down let-through energy to the downstream equipment.
4) Does this Bussmann telecom fuse have a blown-fuse indicator?
No, the TPS-B-30 is the non-indicating version, so there is no indicator pin or window to show it has opened. If your maintenance crew relies on a visual trip indication at the panel, you need an indicating variant of the TPS series instead, because this one has to be checked with a meter or by pulling it.
5) What part number do I order to match an Eaton TPS series 30 amp telecom fuse?
Order Bussmann (Eaton) part number TPS-B-30. That designation covers the TPS series telecommunication fuse at 30 A, 170 Vdc, 100 kAIC, non-indicating. There are no finish or length options to specify on it, just the one model.
6) What is the fuse body made of, and will it hold up in a hot rectifier cabinet?
The tube is glass melamine, which gives the fuse its insulation and mechanical strength, and the ferrules are silver-plated brass for low-resistance contact in the clips. That combination is what Bussmann uses for continuous-duty DC telecom service rather than a plain fiber or glass body.
