Multimeter fuses

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.

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. The whole specification is in the title and a two-line description

What the maker puts in writing

“Digital Multimeter Fast Acting Replacement Fuse, 1000V AC Voltage, 11A AC Current (Pack of 5)”
“Nominal current: 11A”
“Maximum voltage to ground: 1000V”
Country of origin: United States
Pack of 5 · $42.42, so $8.48 a fuse

NO dimensions for the fuse. NO body material. No breaking capacity.

Two figures, stated well

Which is the part of this page that works.

Eleven amps nominal. A thousand volts MAXIMUM TO GROUND.

That second wording is better than the bare number the other two give. What a fuse in a current input has to withstand is the potential between the input and earth, and Fluke says so.

And the first of the hub’s four numbers, missing

“The manufacturer specifies four things about it: dimensions, current rating, voltage rating and breaking characteristic.”

Dimensions come first in that list, and they are not on this page.

The only measurements printed are the BLISTER’S: 19.05 by 13.716 by 0.508 centimeters.

The Klein says 10 × 38 mm (0.39 × 1.50 in) in its title. The YUNFOOK says 10 mm (0.39 in) × 38 mm (1.50 in) and then repeats it in inches. This one says nothing.

Nor whether it is ceramic

Which the shelf’s tag line makes the sharpest omission of the three.

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

Three American fuses on this shelf, all rated 1000 V. One of them — the Klein — names its body material.

Four bullets that are catalog fields

“Product Type: Precision Measuring.”

“Package Dimensions: 19.05 cm (7.5 in) L X13.716 cm (281.9 in) W X0.508 cm (200 in) H.”

“Country Of Origin: United States.”

“Package Quantity: 1” — on a page whose title says pack of five.

The entire specification of this safety component lives in its title and a two-line description underneath.

Five is the right number to buy

Because this is the component that goes on a mistake, not on wear.

Probes across a live supply with the leads still in the 10 A sockets, and the fuse does what it exists to do.

Eight forty-eight each: cheaper than the single Klein at $15.99, dearer than the YUNFOOK pair at $5.85 apiece.

What gets asked here

What size is it?

The page does not say, and that is the gap. This shelf's introduction puts dimensions first among the four things a maker specifies about this component, because a fuse that does not fit the holder is useless and a fuse that fits but is the wrong class is worse. The only measurements printed are the blister pack's: 19.05 by 13.716 by 0.508 centimeters. The other two American fuses on this shelf both state 10 × 38 mm (0.39 × 1.50 in) in their titles. Before ordering five, check the part number against your meter's manual rather than against the dimensions, because the dimensions are not here.

Ceramic or glass?

Not stated, and at 1000 V that is the question worth an email to the seller. The shelf's tag line is that a glass fuse in a meter specifying ceramic is not a substitute: ceramic bodies are sand-filled and quench the arc, glass bodies have air in them. Of the three American fuses here, only the Klein puts the word ceramic in writing. Fluke's reputation is the implicit answer and it is not the same as a published figure.

Why does Fluke sell them five at a time?

Because the fuse in a current input is the component that goes, and it goes on a mistake rather than on wear. Someone puts the probes across a live supply with the leads still in the 10 A sockets, and the fuse does precisely what it is for. A bench with several meters on it wants spares in the drawer, not an order to place. Five at $8.48 each is cheaper per fuse than the single Klein and dearer than the YUNFOOK pair.

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

Klein Tools High-temperature type K thermocouple, 0 to 480 °C (32 to 896 °F)

Klein's high-temperature thermocouple — 480 °C (896 °F), a coiled lead, and no stated accuracy or probe style.

Type and plug fit
Type K, stated, and the ADAPTER IS INCLUDED — "with Adapter" is in the product title. That puts it with the ZIBOO clamp and against the Klein 69140, where the adapter is a separate part number. "Works with any digital multimeter or clamp meter that measures temperature"
Stated temperature range
32 to 896 °F (0 to 480 °C), stated. Nearly FIVE TIMES the ceiling of Klein's own 69140 pipe clamp, which stops at 100 °C (212 °F) — and Klein says so directly: these accessories "extend working temperature ranges for Klein's HVAC Digital Multimeters and Clamp Meters". It does not go below freezing, which the two pipe clamps on this shelf both do
Probe style
NOT STATED. This shelf's introduction makes probe style the thing you choose by the job — a bead for air, a flat pad for surfaces, a sheathed rod for immersion — and this listing says only "High Temperature Thermocouple". There is no bead, no pad, no sheath and no tip dimension anywhere on the page, which is the one specification a buyer needs to know whether it will sit on a flue or in it
Stated accuracy
NOT PUBLISHED. The listing gives only the caveat without the figure: "Accuracy of the thermocouple is dependent on the accuracy of the meter being used." Both pipe clamps on this shelf state ±2% alongside that sentence; this one states the sentence alone, at the highest price of the three Klein parts
Cable length
A COILED lead, 3 feet — the only coiled lead on this shelf, and shorter than either pipe clamp’s meter. Coiled matters on a hot job: a straight lead draped across a flue collects heat along its length, while a coil keeps the cable off the work and pulls back out of the way
Heat resistance
Implied by the 480 °C (896 °F) measuring range and not stated separately for the lead. Klein lists "High Temperature Thermocouple Wire" as a DIFFERENT accessory in the same family, which suggests the wire on this part is not itself the high-temperature item
Also stated
11 grams, the lightest probe weight published on this shelf. Klein names the rest of the K-type family on this page — temperature pipe clamp, temperature probe, high temperature thermocouple wire and banana plug adapter — which is the clearest accessory map any maker on this shelf publishes

Nxtop Sheathed type K probe, 1100 °C (2012 °F), 3 × 200 mm (0.12 × 7.87 in)

The cheapest probe on this shelf, the hottest, and the only one that publishes a dimension for its plug.

Type and plug fit
Type K with a MINIATURE K-TYPE CONNECTOR, and the fork terminal spacing is published: 5 mm (0.20 in), 0.197 inch. It is the ONLY probe on this shelf that gives a dimension for its plug, and this shelf's introduction says in so many words that "the miniature flat plug that connects it is where fit fails". A nine-dollar probe answers the shelf's stated failure point, and the twenty-seven and thirty-dollar Kleins do not
Probe style
A SHEATHED ROD, 3 mm (0.12 in) diameter by 200 mm (7.87 in) long — the immersion style this shelf's introduction names. Total length 29.5 cm (11.6 in) with the cable gland, so roughly 9 cm (3.5 in) of that is body rather than probe. It is the only product on this shelf whose probe geometry is fully dimensioned
Stated temperature range
0 to 1100 °C (32 to 2012 °F), stated. That is the HIGHEST range published by any probe on this shelf: the Klein 69142 reaches 480 °C (896 °F), the published Taiss 350 °C (662 °F), the ZIBOO clamp 200 °C (392 °F) and the Klein 69140 clamp 100 °C (212 °F). Only the Fieldpiece ST4 meter claims more, at 1300 °C (2372 °F), and that is the instrument's range rather than a probe's. Like the Klein 69142 it does not go below zero
Cable length
30 cm (11.8 in), 12 inches, stated "not stretched" — the SHORTEST on this shelf by a wide margin. The two pipe clamps give 102 cm (40.2 in), the Klein 69142 three feet, the published Taiss 3 m (10 ft). Thirty centimeters puts your hand about a foot from whatever is at 1100 degrees, which is the real limit of this probe and has nothing to do with its sensor
Stated accuracy
NOT PUBLISHED, and no tolerance class is named either. Only the two pipe clamps on this shelf publish a percentage at all; this one publishes nothing. At $8.99 that is the trade being offered, and the sentence both Klein clamps print applies here too whether or not it is written: what turns the junction voltage into a number is your meter
Heat resistance
Implied by the 1100 °C (2012 °F) range for the sheath, and unstated for the cable. The listing describes the materials only as "Electronic Parts, Plastic" and the color as yellow, which is the standard color coding for type K in American practice. A plastic-insulated 30 cm (11.8 in) lead is what sets the working distance, not the stainless rod
Also stated
78 grams, against 11 g (0.4 oz) for the Klein 69142. The listing is written as a parts-catalog entry rather than marketing — product name, model, type, color, material, range, weight, fork spacing, probe dimensions, total length, cable length, package contents — and that is why it publishes more dimensions than anything else on this shelf
Amazon reference
B07DNGWLFS
EAN
0703064924915
- Eleven hundred degrees for nine dollars
- The only plug dimension published on this shelf — 5 mm (0.20 in)
- Thirty centimeters of cable, at 1100 degrees
Best for: Kiln, furnace, forge and flue work, where 1100 °C (2012 °F) is the specification and a 30 cm (11.8 in) cable is enough
