B-LINE DBU17-100SE – Frequently Asked Questions
1) What voltage and amperage is the B-Line DBU17-100SE expulsion fuse refill rated for?
The DBU17-100SE is a 100A refill rated 14.4 kV, with a maximum voltage of 17.1 kV. That maximum is the ceiling for the system it goes into, so on a 14.4 kV distribution circuit it sits within rating. Anything above 17.1 kV is out of range for this refill.
2) Is this a complete fuse cutout or just the refill element?
It is the refill only, not a mounting or cutout assembly. The DBU17-100SE is the expulsion fuse refill that goes into an existing fuse holder, so you need a holder already in place on the pole or in the enclosure. Order the holder separately if you are building a new installation.
3) Can I still get mountings for BA refills, or do I need to switch to something else?
Mountings for BA refills are no longer available, though a limited range of replacement fuse holders is. For new installations and replacement work the guidance is to move to RBA fuses, which superseded the BA line. If you are only replacing a blown element in an existing holder that is still serviceable, a refill is the straightforward path; if the mounting itself is failing, plan on the RBA changeover.
4) What does Class SE mean when ordering a DBU expulsion fuse refill?
Class SE identifies the fuse element type, and it has to match what your holder is built to take. The DBU17-100SE is a Class SE refill at 100A. A holder set up for a different class or a different amp rating is not a match, so confirm the class stamped on the existing refill before you order.
5) I am an MRO buyer stocking spares for medium voltage distribution gear. Is the DBU17-100SE a current part to standardize on?
Treat it as a service part rather than a standardization target. It covers 100A at 14.4 kV, 17.1 kV maximum, and keeps existing holders in service. But because mountings for BA refills are discontinued and RBA fuses have superseded BA, new build and replacement applications should be specified with RBA. Stock the DBU refill against the installed base you still have, and spec RBA going forward.
6) Where can I find the published specifications for the DBU17-100SE?
Eaton publishes a spec sheet for the DBU17-100SE, and it is linked from the product information. It covers the 100A Class SE expulsion refill rated 14.4 kV with a 17.1 kV maximum.
