Bussmann TPJ-100 – Frequently Asked Questions

1) Can a Bussmann TPJ fuse be used on a 48V DC telecom power plant?
Yes. The TPJ Series is rated 170 Vac/dc, so it protects both AC and DC circuits, and a 48V DC plant sits well inside that rating. It was built for telecom power distribution, central office and rectifier circuits. Order by amp rating: TPJ-60 through TPJ-150.
2) Does the TPJ fuse have a blown-fuse indicator?
No. The TPJ is the non-indicating version, so there is no indicator pin or window to show it has opened. You verify it with a meter or by continuity check. If your distribution panel relies on a visual or alarm-triggering indicator, the TPJ is the wrong choice and you want an indicating telecom fuse instead.
3) I need to replace a blown fuse in a telecom DC panel - how do I pick the right TPJ part number?
Match the amp rating stamped on the fuse you pulled, then order the matching part: a 100A becomes TPJ-100, a 125A becomes TPJ-125. Do not upsize to get more headroom, because the fuse is sized to protect the downstream conductor and equipment. Confirm the existing fuse is a non-indicating type, since the TPJ has no indicator, and that the panel voltage is at or under 170 Vac/dc.
4) Is the Bussmann TPJ a standard Class J fuse I can drop into a 600V industrial fuse block?
No. Despite the TPJ name, this is a telecommunication fuse rated 170 Vac/dc, not a 600V branch circuit fuse. Using it on a 480V or 600V industrial feeder would exceed its voltage rating. Keep the TPJ to telecom power distribution, central office DC plants and rectifier circuits.
5) What amp ratings does the Bussmann TPJ telecom fuse come in?
Seven ratings: 60A, 70A, 80A, 90A, 100A, 125A and 150A, ordered as TPJ-60, TPJ-70, TPJ-80, TPJ-90, TPJ-100, TPJ-125 and TPJ-150. Nothing below 60A or above 150A in this series, so if your circuit calls for a smaller fuse you need a different Bussmann telecom series.
6) What is the TPJ fuse body made of and does it hold up in a hot equipment room?
The body is a glass melamine tube. It is a rigid thermoset housing rather than a plastic or paper shell, which is why Bussmann uses it on telecom power fuses that live in continuously loaded DC distribution cabinets.
7) Can I stock one TPJ fuse for a whole central office, or do I need several sizes?
You need several. Each TPJ is a single fixed amp rating, so a facility running mixed rectifier and distribution circuits typically carries spares across the range, commonly 60A, 100A and 150A. Buying by rating is the only way to keep the protection matched to each circuit.
