Bussmann T-25 Fusetron Type T Time-Delay Plug Fuse, 25A

The Bussmann T-25 is a Type T plug fuse from the Eaton Bussmann series, engineered as a dual-element, time-delay fuse for heavy-duty branch-circuit protection. Rated 25 A at 125 Vac, this fuse carries a 10 kAIC (RMS Symmetrical) interrupt rating and a 10 kA short circuit rating, making it well suited to residential and light commercial panels that use Type T (Edison-base rejection) fuseholders. Its threaded mount allows straightforward installation into compatible plug-fuse panel sockets, and the dual-element time-delay design lets it ride through temporary motor-starting or appliance inrush currents without nuisance opening, while still responding quickly to genuine overloads and short circuits. This heavy-duty construction makes the T-25 a dependable replacement fuse for panels that call for a 25 A, 125 Vac Type T device.

Key Features

  • Amperage Rating: 25 A dual-element, time-delay fuse for reliable overcurrent protection.
  • Voltage Rating: 125 Vac, suitable for standard residential and light commercial branch circuits.
  • Interrupt Rating: 10 kAIC (RMS Symmetrical) for dependable fault-current interruption.
  • Short Circuit Rating: 10 kA, supporting use on circuits with higher available fault current.
  • Heavy-Duty Time Delay: Dual-element construction resists nuisance opening from temporary current surges such as motor starting or appliance inrush.
  • Type T Configuration: Type T plug fuse design for compatibility with Type T (Edison-base rejection) fuseholders.
  • Threaded Mount: Threaded base for secure installation into compatible plug-fuse panel sockets.

Technical Specifications

  • Refer to manufacturer documentation for complete technical specifications.

Typical Applications

  • Residential and Light Commercial Plug-Fuse Panels
  • Replacement Fuse for Type T (Edison-Base Rejection) Fuseholders
  • Motor and Appliance Branch Circuits Requiring Time-Delay Protection
  • Heavy-Duty Overcurrent Protection on 125 Vac Circuits
  • Panel Upgrades and Maintenance Fuse Replacements

Why Bussmann?

Bussmann fuses from Eaton are built for dependable, code-compliant overcurrent protection, and the T-25 continues that standard with a dual-element, time-delay design rated 25 A at 125 Vac, backed by a 10 kAIC (RMS Symmetrical) interrupt rating and a 10 kA short circuit rating. The threaded, Type T configuration ensures proper fit in compatible fuseholders, giving electricians and facility managers a trusted heavy-duty replacement option for demanding branch-circuit applications.

Bussmann T-1/2 – Frequently Asked Questions

1) Will a Bussmann Type T plug fuse screw into my existing Edison-base fuse panel?
The Bussmann T series is a Type T plug fuse with a threaded Edison base, so it threads into standard plug-fuse panel sockets and Type T (Edison-base rejection) fuseholders. If your panel has Type S rejection adapters already installed in the sockets, a Type T fuse will not go in, Type S fuses are not interchangeable with Type T bases.
2) My fuse keeps blowing when a motor or compressor starts up. Will the Bussmann T-25 solve that?
That is exactly what the dual-element time-delay design in the T-25 is for. It rides through the brief inrush a motor or appliance draws on startup instead of opening, while still clearing a real overload or short circuit. If the fuse is sized correctly for the circuit and the nuisance opening only happens at startup, a 25A time-delay Fusetron is the right replacement. If it opens under steady running load, the problem is the load or the wiring, not the fuse type.
3) Can I use a 125V plug fuse on a 240V circuit like a water heater or dryer?
No. Type T Fusetron plug fuses are rated 125Vac and belong on 120V branch circuits only. A 240V load fed by two legs needs cartridge fuses or a breaker rated for that voltage, not a plug fuse.
4) What amperages does the Bussmann Fusetron Type T plug fuse come in?
Two Type T Fusetron models are offered, T-1/2 and T-25. The T-25 is the 25 amp heavy-duty branch-circuit fuse, and the T-1/2 is a 1/2 amp device for very small loads such as control or signal circuits. Both share the same 125Vac rating and threaded Type T base.
5) What is the difference between a time-delay Fusetron plug fuse and a standard fast-acting plug fuse?
A standard single-element plug fuse opens quickly on any current above its rating, including the momentary surge when a motor or compressor starts. The Fusetron T is dual-element and time-delay, so it tolerates that short surge and only opens on a sustained overload or a fault. Use the time-delay version on motor, compressor, and appliance circuits; a non-delay fuse is fine for purely resistive loads like lighting and receptacles.
6) I'm replacing a blown 25 amp fuse in an older apartment panel. Is the T-25 a direct swap?
If the panel calls for a 25A, 125Vac Type T plug fuse, the T-25 drops straight in. Never go up in amperage to stop repeat blowing, the fuse rating has to match the conductor the circuit was wired with. For fleet work, standardizing on the same Type T Fusetron across buildings keeps one spare on the truck instead of several.
