Bussmann Eaton Series TPC 80Vdc Telecommunication Fuse, Non-Indicating Compact Current-Limiting

The Bussmann Eaton Series TPC is a telecommunication fuse engineered for 80 Vdc systems, delivering a 100 kAIC interrupt rating for reliable current-limiting protection in demanding DC power environments. This compact, non-indicating fuse is built for panels and equipment where board space is limited and a low-profile footprint matters. The TPC series is available across a broad amp rating range from 3A to 125A, giving engineers and installers a single fuse platform to standardize on across multiple circuit protection needs. Its current-limiting design helps reduce let-through energy and protect downstream telecommunication equipment during fault conditions, and as part of the Eaton Bussmann portfolio it is intended for professionals who specify dependable overcurrent protection for DC-powered telecommunication infrastructure.

Key Features

  • Amp Rating Range: Available in 3A, 5A, 6A, 8A, 10A, 15A, 20A, 25A, 30A, 40A, 50A, 90A, 100A, and 125A ratings to match a wide range of telecommunication circuit protection needs.
  • Voltage Rating: Rated 80 Vdc for DC-powered telecommunication and central office power systems.
  • Interrupt Rating: 100 kAIC current-limiting performance helps reduce let-through energy and protect downstream equipment during fault conditions.
  • Non-Indicating Design: Standard non-indicating construction for straightforward, cost-effective circuit protection.
  • Compact Footprint: Compact body sizing suited to space-constrained telecom panels and equipment racks.
  • Current-Limiting Technology: Current-limiting operation helps minimize fault energy and protect sensitive downstream telecommunications equipment during overcurrent conditions.
  • Single-Platform Standardization: A common 80 Vdc, 100 kAIC platform across all 3A-125A ratings simplifies spare-parts stocking and specification.

Bussmann TPC-100 – Frequently Asked Questions

1) Does the TPC fuse have a blown-fuse indicator?
No. The TPC is the non-indicating version, so there is no pop-up pin or flag to tell you it has opened. If your rack or fuse panel relies on a visual or alarm-contact indication to flag an open fuse, the TPC is the wrong choice and you want an indicating telecom fuse instead. For panels where the alarm comes off the distribution unit rather than the fuse body, non-indicating is the straightforward pick.
2) Why choose a current-limiting telecom fuse instead of a standard fuse?
On a DC bus fed by batteries and rectifiers there is no natural current zero to help clear an arc, and available fault current is high. A current-limiting fuse like the TPC opens before the fault reaches its peak, cutting the let-through energy that would otherwise hit downstream telecom equipment and wiring. A non-current-limiting device lets the full fault develop. That difference is why central office and network infrastructure panels get specified with current-limiting DC fuses.
3) Can I standardize my whole DC plant on one fuse series?
That is the practical argument for the TPC. Every rating from 3A through 125A sits on the same 80 Vdc, 100 kAIC platform, so an MRO or central office stockroom carries one series and varies only the amp value. Spare kits get simpler and the spec on the drawing stays constant across circuits.
4) How do I order the right Bussmann TPC fuse?
Pick by amp rating only. Voltage (80 Vdc), interrupting rating (100 kAIC) and the non-indicating body are fixed across the series, so the single decision is the ampere value and the part number follows it directly: TPC-3 at 3 amps, TPC-50 at 50 amps, TPC-100 at 100 amps.
5) Will the TPC fit in a tight telecom fuse panel?
The TPC is built on a compact, low-profile body specifically for panels and equipment racks where board space is limited. It is the reason the series gets specified into central office distribution and network infrastructure panels rather than a general-purpose industrial fuse block. For an exact body length and diameter, match against the fuse holder prep you already have.
