Bussmann TPM-8 Miniature Telecommunication Fuse, 8A, 80Vdc, Current-Limiting

The Bussmann TPM-8 is part of the Eaton Bussmann series TPM telecommunication fuse line, engineered to deliver reliable overcurrent protection for telecommunications and low-voltage DC power distribution circuits. Rated 80 Vdc at 8A with a 20 kAIC interrupt rating, this current-limiting fuse provides dependable fault-clearing performance for sensitive telecom equipment and network power systems. Its miniature, non-indicating, black thermoplastic body supports compact installation where board and panel space is limited, making it a practical replacement or new-build option for telecommunications power distribution designs that call for the TPM series footprint.

Key Features

  • Electrical Rating: Rated 80 Vdc at 8A, suited for telecommunication and low-voltage DC circuit protection.
  • Interrupt Rating: 20 kAIC interrupt capacity delivers reliable fault current clearing under overload conditions.
  • Current-Limiting Design: Current-limiting operation helps reduce let-through energy and protect downstream components during a fault.
  • Non-Indicating: Standard non-indicating construction keeps the design straightforward for telecommunication fuse applications that do not require a visual blown-fuse indicator.
  • Miniature Size: Compact miniature form factor fits space-constrained telecom equipment, boards, and panels where standard fuse sizes will not fit.
  • Durable Construction: Black thermoplastic body provides a rugged, insulated housing around the fuse element for stable performance in service.
  • Series: Part of the Eaton Bussmann series TPM telecommunication fuse family, sized and rated specifically for telecom power circuits.
  • Fuse Type: A dedicated telecommunication fuse designed for DC power distribution rather than general-purpose AC branch circuit protection.

Technical Specifications

Typical Applications

  • Telecommunications Equipment Protection
  • Low-Voltage DC Power Distribution
  • Central Office and Network Equipment
  • Data and Communications Panels
  • Battery Backup and DC Power Systems
  • Telecom Rectifier and Power Plant Circuits

Why Bussmann?

Bussmann by Eaton is a trusted name in circuit protection, and the TPM series telecommunication fuse reflects that reputation with a current-limiting, non-indicating design built for demanding low-voltage DC applications. Its durable black thermoplastic construction and 20 kAIC interrupt rating make it a dependable choice for protecting sensitive telecommunications and network equipment from overcurrent and fault conditions. The miniature form factor allows engineers and technicians to specify a compact, code-appropriate fuse without redesigning existing telecom power distribution layouts. Choose the Bussmann TPM-8 for consistent, current-limiting overcurrent protection in telecom power systems where reliability and a small footprint both matter.

Bussmann TPM-8 – Frequently Asked Questions

1) Is the TPM-8 the right fuse for a central office DC power panel or for an AC branch circuit?
It belongs in DC. The TPM series is a dedicated telecommunication fuse for low-voltage DC power distribution, central office and network equipment, data and communications panels, battery backup systems, and telecom rectifier and power plant circuits. For AC branch circuit protection you want a general-purpose AC fuse class instead, not a TPM.
2) Will the TPM-8 fit a tight telecom fuse position where a standard fuse body is too big?
That is what the TPM series is built for. It is a miniature form factor with a black thermoplastic body, sized for boards and panels where a standard fuse will not physically fit. If you are replacing a fuse in an existing telecom power distribution layout that was built around the TPM footprint, the TPM-8 drops into that same footprint at the 8A rating.
3) Is the TPM-8 fuse an 8 amp rating?
Yes, 8 amps at 80 Vdc. The amp rating is in the part number: TPM-8 is the 8A member of the Bussmann TPM telecommunication fuse series.
4) Does the Bussmann TPM-8 have a blown fuse indicator?
No. The TPM-8 is a non-indicating fuse, so there is no mechanical flag or visual pop-out to show it has opened. You will need to test continuity or rely on alarm circuitry in the panel if you want blown-fuse detection.
5) What does current-limiting mean on a telecom fuse like the TPM-8, and why does it matter?
Current-limiting means the fuse opens fast enough during a high fault to cut off the current before it reaches its full prospective peak, which reduces the let-through energy hitting downstream boards and connectors. On the TPM-8 that works together with its 20 kAIC interrupting rating, so sensitive rectifier and network equipment downstream sees far less thermal and magnetic stress during a short.
6) What is the exact manufacturer part number for the 8 amp Bussmann TPM telecom fuse?
TPM-8, from Bussmann by Eaton, series TPM. That single MPN covers the 8A 80Vdc non-indicating miniature version.
