3M SDR-0 Wire Marker Refill

The 3M SDR-0 refill supplies preprinted legend-0 markers for wire and cable identification. Each roll delivers 576 self-adhesive polyester labels coloured black on white. The markers suit electrical installers, maintenance technicians and panel builders who need quick, legible circuit tags. They fit the STD dispenser and cover wire sizes from 6/0 to 24 AWG.

Temperature range and material stability

The polyester film operates from -40 to 250 degrees F, keeping adhesive bond and print legibility through freeze-thaw cycles and high-heat panels. Labels measure .22 in wide by .003 in thick, so they conform tightly without adding bulk that could snag in tight bundles. One roll per legend keeps inventory simple for repeated service calls.

Installation notes and common issues

Peel each marker from the liner and press onto clean, dry insulation; the self-adhesive backing bonds in seconds. Dirt, oil or moisture on the wire surface is the main cause of premature lifting, so wipe the conductor before applying. The refill loads only into the STD dispenser — other dispensers will not index the roll correctly.

Questions about this item

How much heat can the SDR-0 markers withstand when cables run hot all day?

The polyester film labels are rated for continuous exposure from -40 °F up to 250 °F, so they stay legible on warm equipment.

What dispenser is required to use these SDR-0 refill rolls?

The refill fits the 3M STD dispenser; without it the self-adhesive labels cannot be dispensed cleanly.

Will the SDR-0 markers fit the thinner wires I already have in the panel?

Yes — the markers accommodate wire diameters from 6/0 down to 24 AWG, covering most existing control wiring.
