Thomas & Betts 18RA-250T Male Tab

The 18RA-250T takes 22-18 AWG stranded or solid wire, and the red vinyl insulation sleeve is the standard color code for that range. Insulation OD on the wire can be up to 0.17 inches and still enter the barrel, so it handles thicker-jacketed appliance and fixture wire as well as thin-wall hookup wire.

Yes. It is a male 250 Series tab measuring .250 x .032, which is the common 1/4 inch blade size used across standard female quick disconnects and .250 receptacles. Tab stock thickness is 0.030 inches.

Thomas & Betts recommends the ERG4001 ratcheting tool for this terminal. Also rated for it: WT145C, WT2000, WT112M and ERG4003. Using a listed tool is what keeps the crimp inside the terminal's UL and CSA listing.

Rated to 600V, so it covers 120V, 208V, 240V and 277V line and control work. Temperature rating is 105 degrees C, which is why it holds up in ballast compartments, luminaire channels and motor control enclosures.

The 3M MVU10-250DMX Scotchlok male disconnect terminal is the nearest cross-brand match. Like the 18RA-250T, it is a vinyl insulated male disconnect on the 250 series tab, and it is supplied in packs of 100. The Thomas & Betts 18RA-250T is an insulated vinyl male 250 series terminal with a .250 x .032 tab, brass body with an electro tin-plated finish, rated 600V at 105 degrees C for 22-18 AWG wire.

No. The 3M Scotchlok 951X is a female T-tap disconnect for 22-18 AWG wire, which taps into a run of wire rather than terminating a cut lead, and it is nylon insulated. The Thomas & Betts 18RA-250T is the male half: a vinyl insulated 250 series male tab for 22-18 AWG. Use the 951X only where you are branching off an existing conductor; for a standard crimped female mate to the tab you want a conventional 250 series female disconnect instead.

It ships in packs of 100, with 500 to an outer carton, and orders go in multiples of 100. Priced and sold each. Weight runs 3.75 lbs per 1000 pieces if you are figuring freight on a bulk MRO order.

The terminal body is brass with an electro tin-plated finish. Brass keeps the contact resistance low and the tin plate is what resists oxidation at the crimp and on the mating blade. The vinyl sleeve carries a UL 94 V-0 flammability rating and the part is RoHS compliant.

No. The 18RA-250T is a crimp-on male tab for the end of a cut conductor. For tapping a through conductor without cutting it, use a T-tap such as the 3M Scotchlok 951X female T-tap disconnect, which is also rated 22-18 AWG and will mate with a 250 male blade.

The Thomas & Betts 18RA-250T is crimped with WT145C, WT2000, WT112M, ERG4001 or ERG4003, with ERG4001 the recommended tool, and it is an insulated vinyl barrel for 22-18 AWG. The 3M MVU10-250DMX is also a vinyl insulated male disconnect, so any insulated-barrel crimp die sized for the 22-18 range covers the same joint style; confirm your existing tool carries an insulated-terminal nest rather than an open-barrel die before swapping.

The A dimension is 0.95 inches, which is what to allow for when you are figuring how much room the finished crimp needs behind a device or inside a tight ballast channel.

The Thomas & Betts 18RA-250T uses insulated vinyl, color coded red, with a UL 94 V-0 flammability rating and a 105 degree C temperature rating. The 3M Scotchlok 951X is nylon insulated. Nylon sleeves are generally chosen for abrasion resistance in harness work, vinyl for easier stripping and flexibility in panel and appliance wiring; both are standard for 22-18 AWG terminations.
