Product Overview
Westinghouse T2A/250V Slow-Blow Micro Fuse, 2A at 250V, Radial Leads, Unused
Condition
Unused new old stock. In the photographs the black molded body is clean, with no chips, cracks, or heat discoloration, and the only thing on it is the factory lettering. Both leads are straight, bright, and unformed, with no solder residue and no oxidation. The end face carries molded lettering that reads FUSE, T2A, and 250V around a circled W, plus a small second circled mark next to the logo that is not legible enough to identify. Photographed against the PartsMine millimeter scale, one piece from the lot.

Product Overview
This is a subminiature radial-lead fuse, the kind that solders directly into a board instead of sitting in a clip or a panel holder. The body is a short black molded cylinder measuring roughly 8 mm across against the millimeter scale, with two straight leads leaving the same end face, so it stands upright on a PCB and takes almost no room. The rating molded into that face is T2A 250V: T for time delay, 2 amps, 250 volts. Slow-blow response is the point of the T prefix, letting transformer and motor inrush pass without a nuisance opening while still clearing a sustained overload. Westinghouse marked it with the circled W rather than a paper label, so the identity is still readable on parts this old. Buyers also search this shape as a micro fuse, a sub-miniature fuse, or a PCB-mount radial fuse.

Applications
- Vintage television and audio techs replacing a board-soldered fuse in a set that was never built for a clip-held cartridge
- Instrument repair benches restocking 2A time-delay protection for low-power supply rails
- Industrial controls maintainers keeping a legacy Westinghouse-era board original down to the fuse
- Prototypers who want the fuse soldered into the board rather than rattling in a holder
Frequently Asked Questions
What exactly is molded into the fuse, and can you read it in the photos?
Yes. The end view shows raised lettering: FUSE across the top, T2A on the left, 250V at the bottom, and the circled W Westinghouse logo in the center. A second small circled mark sits to the right of the logo. It is not sharp enough to identify, so we are not naming it.
What does T2A/250V mean?
T is the time-delay, or slow-blow, designation. 2A is the rated current. 250V is the maximum rated operating voltage. A slow-blow fuse rides out brief inrush current instead of opening on it.
How big is it, and will it fit my board?
Against the millimeter scale in the first photo the body measures approximately 8 mm across and about the same in length, with two straight leads from one end. Lead spacing is not confirmed here, so check your board hole pitch against the photos before ordering.
Can I use it on a DC rail?
The body is marked 250V with no AC or DC qualifier, and we do not have the original Westinghouse data for this part. Not confirmed - verify the DC interrupting behavior against fuse manufacturer data before relying on it in a DC circuit.
Why buy three or five of these here instead of a bag of fifty somewhere else?
Because a fuse repair usually needs two: the one you install and the one you keep in the drawer. We stock these deep and sell them by the piece, so you buy the count your job actually calls for instead of a forced lot of 50 that lives in a parts bin for a decade. Shipping is $8 flat rate and free once the order clears $28, and orders leave our Idaho warehouse the same or next business day.
Westinghouse molded its circled W into a fuse the size of a pencil eraser, which tells you something about a company that signed even the parts nobody was meant to look at. Solder it in and the board gets its first line of defense back.
