Stated dimension or range
5 × 20 mm (0.20 × 0.79 in) ceramic
Fuse rating
10 A / 250 V · time-delay (T)
All four figures published: 5 × 20 mm (0.20 × 0.79 in), 10 A, 250 V, time-delay
Ceramic bodies, which is what a meter's current input normally specifies
A 250 V rating is below what many meters specify for the current input
Best for: The meter whose manual specifies exactly 5 × 20 mm (0.20 × 0.79 in), 10 A, 250 V, time-delay — and no other.
A fuse is a safety component with four specifications, and this listing gives all four.
What the manufacturer publishes
Ten SeKi G-fuses. A rated current of 10 A and a rated voltage of 250 V. A time-delay tripping characteristic. Dimensions of 5 × 20 mm (0.20 × 0.79 in), ceramic.
The rule, and it has no exceptions
Replace with the exact part the manual specifies. Not the fuse that fits the holder, not the one with the same current, not the glass one from the drawer. Four figures have to match: size, current, voltage and characteristic.
The reason is what the fuse does when a meter is connected across a supply with the dial on amps. That is a near short circuit, and the fuse is the only thing that interrupts it. A fuse of the wrong type either fails to clear or fails destructively.
Where 250 V is not enough
Many instruments specify a higher voltage rating on the current input precisely because of that scenario. If your manual says 600 V or 1000 V, this fuse is not the part, whatever its current rating.
Availability
No such listing: the American Amazon shop answers the reference with a search box rather than a page.
Read from Keepa on the day this page was last revised; stock and price both move without notice.
What gets asked here
Can I fit any fuse that physically fits?
No. This is one of the very few places on this site where a substitution is a safety matter rather than a preference. The manual specifies dimensions, current, voltage and breaking characteristic, and all four have to match.
Why ceramic rather than glass?
A ceramic sand-filled body is specified where the fuse must interrupt a high-energy fault. A glass fuse of the same current rating does not do the same job and can fail violently.
What does "T" or time-delay mean?
The fuse tolerates a brief overload before opening. A fast fuse in a time-delay position blows on every start-up; a time-delay fuse in a fast position does not protect what it was meant to.
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

Five eighty-five a fuse, the cheapest 1000 V part here
Dimensions in millimeters and in inches
No body material: ceramic or glass is never said
Best for: Keeping spares for an 11 A / 1000 V current input, where the manual gives a part number rather than a brand
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. The whole specification is in the title and a two-line description

Eight forty-eight a fuse, five in the pack
The voltage stated properly, as potential to ground
No dimensions on the page — the hub asks for them first
Best for: A workshop running Fluke meters, where the part number in the manual is the specification and spares are kept by the handful
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
