Bussmann UHW-T Non-Indicating Cable Limiter, Center Bolt x Offset Bolted End
The Bussmann UHW-T is an Eaton Bussmann series UHW cable limiter engineered with a center bolt end x offset bolted end configuration for secure, code-compliant conductor termination. This non-indicating cable limiter is rated for 350 kcmil copper conductors and 500 kcmil aluminum conductors, giving installers a single device that covers both common conductor types at cable splice and termination points in power distribution systems. Cable limiters like the UHW-T are used where dependable, protected conductor connections are required in demanding electrical distribution environments, and the bolted-end design supports a solid mechanical and electrical connection at each end of the splice.
Key Features
- Dual Conductor Rating: Rated 350 kcmil for copper conductors and 500 kcmil for aluminum conductors, covering both common conductor types in a single cable limiter.
- Center Bolt x Offset Bolted End Configuration: Center bolt end paired with an offset bolted end for secure, properly aligned termination at cable splice points.
- Non-Indicating Design: Standard non-indicating construction, without a blown-element indicator, for straightforward cable limiter applications.
- Eaton Bussmann Series UHW: Part of the Eaton Bussmann series UHW cable limiter line, built for dependable performance in power distribution circuits.
- Bolted Termination: Bolted-end construction on both ends supports a secure mechanical and electrical connection at the splice.
- Copper and Aluminum Coverage: A single UHW-T limiter accommodates both 350 kcmil copper and 500 kcmil aluminum conductor sizes, simplifying stocking for electrical distributors and contractors.

Bussmann UHW-T – Frequently Asked Questions
1) What conductor sizes does the Bussmann UHW-T cable limiter fit?
The UHW-T is rated for 350 kcmil copper and 500 kcmil aluminum conductors. One limiter covers both metals at those sizes, so you don't need a separate part number depending on whether the feeder is copper or aluminum. If your run is a different kcmil size, this is not the right limiter.
2) What end configuration does the UHW-T have, and will it line up at my splice?
Center bolt end on one side, offset bolted end on the other. The offset end is there to bring the termination into alignment where the two cable ends don't sit on the same centerline. Both ends are bolted, so each side makes a mechanical and electrical connection with hardware rather than a crimp or compression barrel. If both of your terminations sit flush on the same plane, a straight bolted-end limiter is the better match.
3) Does the Bussmann UHW-T show when it has operated?
No. The UHW-T is a non-indicating limiter, so there is no blown-element indicator to look at. Troubleshooting a suspect limiter means testing it, not inspecting it. If your maintenance crew relies on visual checks in a vault or network manhole, specify an indicating version of the UHW series instead.
4) What is a cable limiter used for, and how is it different from a fuse in the switchgear?
A cable limiter is installed at the cable itself, at splice and termination points, to protect the conductor run. The UHW-T sits in that role in power distribution circuits: underground and network distribution, utility and substation cable connections, and commercial or industrial feeders. Overcurrent devices in the gear protect the circuit as a whole; a limiter isolates a faulted individual cable in a multi-cable feeder so the rest of the run keeps serving load.
5) Can I use the UHW-T on both the copper and the aluminum feeders in the same job?
Yes, within the stated sizes. Rated 350 kcmil on copper and 500 kcmil on aluminum, the same UHW-T can be stocked for both conductor types, which is why distributors and contractors carry it as a single line item rather than two.
6) What is the exact part number to order for the Bussmann UHW series center bolt x offset bolted end limiter?
Order it as Bussmann UHW-T. That single part number covers the center bolt end x offset bolted end, non-indicating configuration rated 350 kcmil copper / 500 kcmil aluminum. Other end configurations within the Eaton Bussmann UHW series carry different suffixes, so the T designation is what identifies this one.
