Multimeter fuses

YUNFOOK Fast-acting fuse, 11 A, 10 × 38 mm (0.39 × 1.50 in), pair

The cheapest 1000 V fuse per piece on this shelf, and the only one that names the part number it replaces.

YUNFOOK DMM-11A multimeter fuses, two in a pack

YUNFOOK Fast-acting fuse, 11 A, 10 × 38 mm (0.39 × 1.50 in), pair

The cheapest 1000 V fuse per piece on this shelf, and the only one that names the part number it replaces.

Stated dimension or range
10 mm (0.39 in) × 38 mm (1.50 in), stated, and then repeated in inches as 0.41" × 1.50". That is the high-energy instrument format, the same as the Klein on this shelf — and more than the Fluke page gives, which publishes no fuse dimensions at all
Current rating
11 A, stated, matching the Fluke and differing from the Klein's 10 A. The listing adds a sentence the other two do not: "Always verify these specifications match your meter's original fuse before installation. Using an incorrect fuse can be a serious safety hazard" — which is this shelf's buying tip, written by the seller
Voltage rating
1000 V AC and DC, stated. Both polarities named, which the other two leave implicit. No fuse previously published on this shelf is rated above 690 V
Breaking characteristic
Fast-acting, stated, with the reason given: "rapid protection for your meter's sensitive internal circuitry (and for you) in case of accidental overload". No breaking capacity in kiloamps is published
Body type
NOT PUBLISHED. Five long bullets and a page of prose, and nowhere does it say ceramic or glass. The shelf's tag line is that a glass fuse in a meter specifying ceramic is not a substitute, and this is a 1000 V part — which is precisely where the distinction bites
Supplied
TWO fuses, $11.69, so $5.85 each — the cheapest 1000 V piece on this shelf. The Fluke five-pack is $8.48 each and the single Klein is $15.99. For a drawer that wants one spare rather than four, a pair is the sensible quantity
Also stated
A direct replacement for multimeter fuse part number 803293, and stated to suit meters from Fluke, Amprobe, BK Precision and Klein Tools that specify an 11 A / 1000 V fuse, with "check your meter's manual to confirm". It is the only fuse on this shelf that names the part number it stands in for, and it names BRANDS rather than models

What the maker puts in writing

  • “DMM-11A Digital Multimeter Fuse, 11A 1000V Fast-Acting – 10x38mm (0.39 × 1.50 in)”
  • “exact electrical ratings of 11 Amps at 1000 Volts AC/DC and the standard physical dimension of 10mm (0.39 in) x 38mm (1.50 in) (0.41” x 1.50”)”
  • “A direct, drop-in replacement for common multimeter fuse part number 803293”
  • “Universally compatible with … many from Fluke, Amprobe, BK Precision, Klein Tools, and others. (Check your meter’s manual to confirm.)”
  • “Always verify these specifications match your meter’s original fuse before installation”
  • Two to a pack · $11.69, so $5.85 a fuse

NO body material. No breaking capacity.

The cheapest 1000 V fuse on this shelf

Five dollars eighty-five a piece.

The Fluke five-pack works out at $8.48 each. A single Klein is $15.99.

Three of the hub’s four numbers are on the page and they match the branded parts: 10 × 38 mm (0.39 × 1.50 in), 11 A, 1000 V AC and DC, fast-acting.

It is the only one that names what it replaces

Part number 803293.

The Klein names three of its own meters. The Fluke names nothing at all. This one names the PART, which is what a manual gives you.

And then it names brands rather than models — “many from Fluke, Amprobe, BK Precision, Klein Tools” — with the caveat printed: check your meter’s manual to confirm.

Its own listing writes the buying tip

“Always verify these specifications match your meter’s original fuse before installation. Using an incorrect fuse can be a serious safety hazard.”

This shelf’s buying tip this shelf says the same thing: replace with the exact part the manual specifies, not with the fuse that fits.

No other fuse on this shelf prints that warning on its own page.

And then the one thing it never says

Five long bullets. A page of prose about why the right fuse is non-negotiable.

Nowhere does it say CERAMIC or GLASS.

“A glass fuse in a meter that specifies ceramic is not a substitute.”

Ceramic is packed with sand that quenches the arc. Glass has air in it.

At a thousand volts that is the difference between opening and rupturing — and this is a thousand-volt part whose listing argues at length that body specification is non-negotiable, without stating its own.

What gets asked here

Can it really replace a Fluke part?

It states that it replaces part number 803293 and suits meters from Fluke, Amprobe, BK Precision and Klein Tools that specify an 11 A / 1000 V fuse — and its own listing adds "check your meter's manual to confirm". That caveat is the honest part. A fuse is defined by its dimensions, its current, its voltage and its breaking behavior, and this one publishes three of the four. What it does not publish is the body material, and that is the fourth thing the shelf above says decides whether a substitution is safe.

Why is it half the price of the branded parts?

Because you are not paying for a meter maker to stand behind it. Per fuse: $5.85 here, $8.48 for the Fluke five-pack, $15.99 for a single Klein. The specification on the page matches the branded parts on current, voltage, format and characteristic. The gap is in what is NOT on the page — no body material, no breaking capacity, no named meter model, and no manufacturer of instruments whose reputation rides on it.

Ceramic or glass, and does it matter at eleven amps?

Not stated, and yes it matters — more at 1000 V than at any current rating. Ceramic bodies are packed with sand that quenches the arc as the element melts; glass bodies contain air and let you see the broken wire. At the energy a 1000 V current input can deliver into a fault, a glass body can rupture rather than open. Of the three American fuses on this shelf, only the Klein writes the word ceramic. If your manual specifies a ceramic fuse, ask the seller before fitting this one.

  • Fluke 203406 replacement fuses in a five-piece blister pack

    Fluke Fast-acting fuse, 11 A, 1000 V, five-pack

    The Fluke part, five to a pack — and the only fuse on this shelf whose own page never states its size.

    Current rating
    11 A nominal, stated. This shelf's introduction asks for the current rating first among the electrical figures, and this is one of two things the page is clear about. It matches the YUNFOOK and differs from the Klein's 10 A, which is exactly the kind of difference this shelf's buying tip warns not to paper over
    Voltage rating
    1000 V, stated as "maximum voltage to ground: 1000V". That wording is more precise than the bare figure the other two give, and it is the right way to state it: what a fuse in a current input has to withstand is the potential between the input and earth
    Breaking characteristic
    Fast-acting, stated in the title. No breaking capacity in kiloamps is published, and neither of the other two American fuses on this shelf publishes one either
    Stated dimension or range
    NOT PUBLISHED. This shelf's introduction names dimensions as the FIRST of the four things a manufacturer specifies about this component, and the only dimensions on this page are the BLISTER's — 19.05 × 13.716 × 0.508 cm (7.5 × 5.4 × 0.2 in). The Klein and the YUNFOOK both state 10 × 38 mm (0.39 × 1.50 in); this page leaves a buyer to work it out from the part number
    Body type
    NOT PUBLISHED. Nothing on the page says ceramic or glass. The shelf's tag line is that a glass fuse in a meter specifying ceramic is not a substitute, and this is a 1000 V part — the energy level at which the distinction stops being academic
    Supplied
    FIVE fuses, $42.42, so $8.48 each. That sits between the YUNFOOK at $5.85 and the Klein at $15.99. A five-pack is the right quantity for a bench that blows them: the fuse in a current input is the component that goes when somebody probes a live circuit in the 10 A socket
    Also stated
    Country of origin: United States. The four bullets on this listing are generic catalog fields — "Product Type: Precision Measuring", "Package Dimensions", "Country Of Origin", "Package Quantity: 1" — rather than anything about the fuse.

  • Klein Tools 69034 ceramic replacement fuse, 10 by 38 millimeters

    Klein Tools Fast-acting ceramic fuse, 10 A, 10 × 38 mm (0.39 × 1.50 in)

    The only fuse here that states dimensions, current, voltage and body material — and the most expensive per piece by a wide margin.

    Body type
    FAST-ACTING CERAMIC, stated in so many words. This shelf's introduction says ceramic sand-filled bodies are specified where the meter must interrupt a high-energy fault and that a glass fuse of the same current rating does not do the same job. Of the three American fuses on this shelf, this is the ONLY one that puts its body material in writing
    Stated dimension or range
    10 × 38 mm (0.39 × 1.50 in), stated in the product title. That is the high-energy instrument format — markedly larger than the 5 × 20 mm (0.20 × 0.79 in) and 6.3 × 32 mm (0.25 × 1.26 in) bodies of the three fuses already published here
    Current rating
    10 A, stated. The two other American fuses on this shelf are both 11 A, so this is the only 10 A part of the three — and this shelf's introduction is explicit that you replace with the exact part the manual specifies, not with the fuse that fits
    Voltage rating
    1000 V, stated. No fuse previously published on this shelf is rated above 690 V. A 1000 V rating is what a CAT III or CAT IV current input needs, and it is the figure that most often differs between the right fuse and the one that fits the holder
    Breaking characteristic
    Fast-acting, stated. Klein adds that it "reduces the risk of internal arc flashes during operation" — which is the whole purpose this shelf's introduction describes: a fuse in a current input is a safety component before it is a consumable
    Supplied
    ONE fuse, at $15.99. That is the most expensive piece on this shelf by a long way: the YUNFOOK two-pack works out at $5.85 each and the Fluke five-pack at $8.48 each. Klein states compatibility with its MM600, MM700 and MM720 meters, and notes Cat. No. 69035 as a companion part
    Also stated
    Klein also claims "long-lasting performance" and "reliable and safe", which say nothing measurable. Two of the seven bullets on this listing are of that kind — and on a safety component, the four numbers matter and the adjectives do not

  • ZIBOO type K pipe temperature clamp with banana plug adapter

    ZIBOO Type K pipe clamp, −40 to 200 °C (-40 to 392 °F), with adapter

    A clamp that carries Klein's part number in its own title and claims double the original's range for half the price.

    Type and plug fit
    Type K, stated, and the BANANA PLUG ADAPTER IS INCLUDED — which is the genuine advantage over the Klein 69140, where the adapter is Cat. No. 69146 and sold separately. ZIBOO then notes that the adapter is "also sold separately (Cat. No. 69146)", quoting Klein's catalog number for a part it has put in its own box
    Probe style
    A PIPE CLAMP, closing round pipes from 1/4 to 1 1/2 inch — an eighth of an inch more than the Klein 69140 claims. Like that clamp, it is a style this shelf's introduction does not name among its bead, pad and rod
    Stated temperature range
    −40 to 392 °F (−40 to 200 °C), claimed. The Klein 69140, whose part number is in this product's title, states −4 to 212 °F (−20 to 100 °C). That is NEARLY TWICE the span, and twice the ceiling, on a copy that costs $14.99 against $26.98. Nothing on either page explains the difference, and a clamp reading 200 °C (392 °F) would reach a hot gas discharge line the original cannot
    Stated accuracy
    ±2%, the same figure the Klein 69140 gives, followed by the same sentence: "Thermocouple accuracy is dependent on the accuracy of the meter being used." The wording of this listing follows the Klein listing bullet for bullet — wide temperature range, versatile pipe clamp, flexible lead, universal compatibility, dependable accuracy — in the same order
    Cable length
    39.78 inches, 102 cm, flexible. The Klein 69140 states 40 inches for the same 102 cm (40.2 in). Thirty-nine point seven eight inches is 101.04 cm (39.8 in), so the figure has been converted from the metric and given to two decimals rather than measured
    Clamp capacity
    Pipes 1/4 to 1 1/2 inch, then "(up to 35 cm (13.8 in))" — the same parenthesis that appears on the Klein page, where it is equally wrong. One and a half inches is 38 Millimeters. Thirty-five centimeters is not a pipe this clamp or any other on this shelf would close around
    Also stated
    The reference field reads 69028+69146 — two Klein Tools catalog numbers concatenated, 69146 being the banana adapter. The title opens "ZIBOO 69140 K-Type Thermometer", and 69140 is the Klein part number of the clamp sitting next to it in this same relevé. The brand on the box is ZIBOO; the part numbers on the listing are all somebody else's

  • Bionso 25-piece multimeter test lead kit with interchangeable gold-plated probes

    Bionso 25-piece probe kit with threaded tips

    Five tip sizes, two hooks, two back probes and a wrench to swap them — and not a single rating figure on the page.

    Stated rating
    NO CATEGORY AND NO VOLTAGE PUBLISHED. Twenty-five pieces, $29.99, five bullets of specification, and not one figure for category, voltage or current. It is one of five sets on this shelf that publish no category at all, with the Fluke TL175, the AUTOOL kit, the KAIWEETS set and the PeakTech pair. This shelf's introduction makes stated ratings the first of its five comparisons, and the published PeakTech fiche on this shelf says a rating should be in the listing
    Insulation
    SILICONE, "cold and high temperature resistant, very soft, more flexible use", double insulated, with "100 high-purity copper wire" — a phrase that is presumably meant to read 100 per cent. No temperature figures and no gauge. Silicone is the material this shelf's introduction prefers over PVC
    Plugs and tips
    REPLACEABLE gold-plated probes in five sizes: four at 1.0 mm (0.04 in), two at 2.0 mm (0.08 in), two 3.8 mm (0.15 in) banana plug probes and two 0.7 mm (0.03 in) back probe pins, plus two test HOOKS that clip onto a component leg and stay there. Two TIP SHROUDS are included — cover for the exposed metal, which only the Fluke otherwise addresses on this shelf, and here as a separate part rather than an adjustable sleeve
    Length
    43 inches, 109 cm, for the two leads. Mid-length on this shelf: under the PUKAIBUL's 125 cm (49.2 in) and the published PeakTech's 120 cm (47.2 in), over the Klein 69410's 104 cm (40.9 in)
    Supplied
    Two 43-inch leads, two handles, four 1.0 mm (0.04 in) probes, two 2.0 mm (0.08 in) probes, two 3.8 mm (0.15 in) banana plug probes, two 0.7 mm (0.03 in) back probe pins, two alligator clips, two tip shrouds, ONE WRENCH, two test hooks and two storage boxes. Twenty-five pieces. The wrench is the only tool supplied with anything on this shelf, and it exists because threaded tips have to be nipped up rather than finger-tight. 210 grams
    Also stated
    A three-month refund and a two-year warranty, both stated. Bionso claims the kit "works perfectly with any multimeter, clamp meter or test instrument", which is a compatibility claim and not a rating. Compared with the published AUTOOL set on this shelf, which runs to 68 pieces, this is the smaller of the two big kits
