Bussmann T-6-1/4 Fusetron Dual-Element Time-Delay Plug Fuse, 6-1/4A

The Bussmann T-6-1/4 is a Fusetron dual-element, time-delay plug fuse rated at 6-1/4A, designed to provide dependable overcurrent protection for low-amperage branch circuits. Its dual-element construction pairs a fast-acting short-circuit element with a separate time-delay overload element, allowing the fuse to ride through harmless momentary overloads while still opening quickly under a genuine fault condition. As a plug-style fuse, the T-6-1/4 threads directly into a standard plug fuse holder, making it a convenient, drop-in replacement for older fuse panels that use this base configuration. The T-6-1/4 designation identifies this unit within Bussmann's T-series Fusetron plug fuse lineup at the 6-1/4A rating.

Key Features

  • Amperage Rating: 6-1/4A rating is sized specifically for low-amperage branch circuits such as lighting and control circuits, providing precise overcurrent protection without oversizing.
  • Fusetron Dual-Element Design: combines a fast-acting short-circuit link with a thermal time-delay element so momentary inrush currents and temporary overloads do not cause nuisance fuse blows, while true overcurrent faults still clear quickly.
  • Plug Fuse Configuration: threads directly into a standard plug fuse holder/socket, allowing straightforward installation and replacement without rewiring the panel.
  • Type T Series Identification: the T-6-1/4 model designation clearly identifies the amperage rating and Fusetron series for accurate replacement matching.
  • Time-Delay Protection: the time-delay characteristic accommodates normal starting currents of motors and other inductive loads on the protected circuit while still protecting against sustained overloads and short circuits.

Technical Specifications

  • Refer to manufacturer documentation for complete technical specifications.

Typical Applications

  • Overcurrent Protection for Branch Circuits
  • Replacement Fuse for Legacy Plug-Fuse Electrical Panels
  • Residential and Light Commercial Electrical Systems
  • Protection of Lighting, Control, and Small Appliance Circuits
  • Fuse Panel Maintenance, Repair, and Upgrades

Why Bussmann?

Bussmann's Fusetron dual-element fuse technology is engineered to tell the difference between a harmless, temporary overload and a genuine fault condition, reducing unnecessary fuse replacements while still delivering reliable protection when it counts. The T-6-1/4 plug fuse carries this proven dual-element design forward in a compact, easy-to-install plug format that electricians and facility maintenance teams have relied on for dependable circuit protection in fuse-panel installations. Choosing a Bussmann Fusetron plug fuse means choosing a fuse built around a well-established, time-tested overcurrent protection technology.

Bussmann T-6-1/4 – Frequently Asked Questions

1) Will a Bussmann T-6-1/4 plug fuse thread into my old fuse panel's socket?
The T-6-1/4 is a plug-style fuse that threads directly into a standard plug fuse holder, so it drops into legacy fuse panels built for that base without any rewiring. If your panel takes screw-in plug fuses, this is the form factor you want.
2) What does dual-element time-delay mean on a Fusetron plug fuse, and when do I need it?
Dual-element means two protection paths in one fuse: a fast-acting short-circuit link and a separate thermal time-delay overload element. The delay lets the fuse ride through motor starting current and other momentary inrush without blowing, while a real short still clears fast. Use it on circuits feeding motors, compressors, or other inductive loads where a standard fast-acting plug fuse nuisance-trips.
3) Is 6-1/4 amps the right size fuse for a lighting or control circuit?
The Fusetron T-6-1/4 is rated 6-1/4A, a low-amperage size intended for branch circuits like lighting, control, and small appliance loads rather than general-purpose receptacle circuits. Size the fuse to the circuit conductor and load as the panel schedule calls for, not to the largest fuse the socket accepts.
4) Can I use a T-6-1/4 to replace a plain fast-acting plug fuse that keeps blowing on startup?
That's exactly the swap the Fusetron design is meant for. A non-delay plug fuse opens on the brief inrush from a motor or transformer; the T-6-1/4's time-delay element holds through that while its short-circuit element still responds to a genuine fault. Keep the same amp rating the circuit calls for, 6-1/4A in this case, and change only the fuse type.
5) What exactly do I order to get the Bussmann 6-1/4 amp Fusetron plug fuse?
Order by Bussmann part number T-6-1/4. That designation carries both the Fusetron Type T series and the 6-1/4A rating, so there is no separate option to pick beyond the model itself.
6) Where can I get the manufacturer data sheet for the Bussmann T-6-1/4?
Eaton/Bussmann publishes a spec sheet for the Fusetron plug fuse, linked in the product's technical documentation at https://media.distributordatasolutions.com/eaton/2019q2/b408a74a096a0cf0402a489b9b19400f731f3abb.pdf. That is where to confirm voltage rating, interrupting rating, and time-current curve for a submittal.
