Bussmann TPL-BG Eaton Series Current-Limiting Telecommunication Fuse, 175A

The Bussmann TPL-BG is an Eaton Bussmann series TPL current-limiting telecommunication fuse engineered for demanding DC power protection applications in telecom and data infrastructure. Rated 170 Vdc and 175A with a 100 kAIC interrupt rating, this fuse delivers current-limiting protection for DC power systems where reliable, high-speed fault clearing is critical to protecting sensitive downstream equipment. The non-indicating design features a bolted blade end by bolted blade end terminal configuration with silver-plated terminals, providing low-resistance, corrosion-resistant connections built for continuous-duty DC power environments. As part of the widely specified Eaton Bussmann TPL series, this fuse is intended for telecommunication power distribution panels and DC circuit protection where a 175A, 170 Vdc, 100 kAIC current-limiting device is required.

Key Features

  • Voltage Rating: 170 Vdc rating suited to telecommunication and industrial DC power distribution systems.
  • Amperage Rating: 175A continuous current rating for dependable, sustained circuit protection.
  • Interrupt Rating: 100 kAIC interrupting capacity delivers reliable protection in high fault-current DC environments.
  • Current-Limiting Design: Current-limiting operation reduces let-through energy during fault conditions, helping protect downstream conductors, bus bars, and connected equipment from damage.
  • Bolted Blade Terminals: Bolted blade end by bolted blade end terminal configuration provides a secure, vibration-resistant, low-resistance mechanical connection at both ends of the fuse.
  • Silver-Plated Terminals: Silver-plated terminal surfaces minimize contact resistance and resist corrosion, supporting consistent performance over the fuse's service life.
  • Non-Indicating: Non-indicating body style suited to standard telecommunication fuse panel installations where visual blown-fuse indication is not required.

Technical Specifications

  • Refer to manufacturer documentation for complete technical specifications.

Typical Applications

  • Telecommunication Power Distribution Systems
  • DC Power Protection for Telecom and Data Center Equipment
  • Central Office and Data Center Power Panels
  • Battery Backup and Rectifier Circuit Protection
  • Industrial and Commercial DC Circuit Protection
  • DC Bus and Distribution Panel Fusing

Why Bussmann?

Bussmann by Eaton is a widely trusted name in circuit protection, and this TPL series current-limiting fuse reflects that standard with a 100 kAIC interrupt rating, a 175A continuous rating at 170 Vdc, and silver-plated terminals for dependable, low-resistance connections. The bolted blade end by bolted blade end terminal design supports a secure mechanical and electrical connection in demanding telecommunication power environments. Specifying a Bussmann TPL series fuse means choosing current-limiting, non-indicating DC circuit protection engineered for the reliability that telecommunication and data infrastructure power systems require.

Bussmann TPL-BB – Frequently Asked Questions

1) What amp ratings does the Bussmann TPL telecommunication fuse come in?
The TPL series is offered in six amperages: 80A (TPL-BB), 90A (TPL-BC), 125A (TPL-BE), 150A (TPL-BF), 175A (TPL-BG) and 350A (TPL-CO). All are 170 Vdc current-limiting telecom fuses, so you pick by the continuous load on the DC feed you are protecting.
2) How does the TPL fuse mount in a telecom fuse panel?
Both ends are bolted blade, end by end, so it bolts directly to the bus or landing pads rather than dropping into clips. The terminals are silver plated to keep contact resistance low and resist corrosion. Plan on torqued bolted connections at both ends, which is also what makes it hold up to vibration in a continuous-duty DC panel.
3) What fault current can the Bussmann TPL fuse interrupt?
100 kAIC. That matters on large battery strings and paralleled rectifier plants, where available DC fault current at the distribution bus can be very high. The fuse is also current limiting, so it cuts let-through energy during the fault and reduces stress on downstream conductors, bus bars and connected equipment.
4) Is the TPL fuse an AC fuse or DC only?
It is a DC device. The rating published for the TPL series is 170 Vdc, so specify it for DC power distribution, not AC branch circuits. For AC panel work you want an AC-rated class fuse instead.
5) Will a TPL fuse show me which one has blown?
No. The TPL is a non-indicating body style, so there is no pop-out pin or visual flag. In a panel where technicians need at-a-glance identification of an open fuse, you would need an indicating-style fuse or an alarm circuit in the panel itself.
6) Is the TPL series suitable outside telecom, for industrial DC circuits?
Yes. Although it is named a telecommunication fuse, the stated applications include industrial and commercial DC circuit protection and DC bus and distribution panel fusing, in addition to central office and data center power panels. The deciding factors are the same: 170 Vdc or less, load within the fuse amperage, and bolted blade landings at both ends.
