Quick-disconnect terminals for 10-12 AWG

These yellow vinyl-insulated disconnects accept 10 to 12 AWG wire and feature a brass body with tin plating. The butted-seam barrel crimps onto the conductor for a secure connection. Each terminal mates with a standard 0.25-inch by 0.032-inch tab. The pack contains 25 pieces for wiring harness work.

Suits maintenance and harness builds needing

Technicians making quick-disconnect splices on 10-12 AWG circuits will find the crimp termination and partial vinyl insulation practical. Installers requiring fully insulated housings, solder termination or screw-down clamping should look at alternative connector styles that provide those features.

0.25-inch tab width matches common automotive tabs

The terminal socket is sized for a 0.25-inch wide tab with 0.032-inch thickness, the standard dimension for many automotive and industrial quick-disconnect blocks. Verifying the mating tab width against this 0.25-inch spec confirms the disconnect will seat correctly.

Questions about this item

How do I crimp these 10-12 AWG disconnects and what step causes loose connections?

Strip the wire to expose the conductor, insert it fully into the .128 in. barrel so insulation touches the barrel end, then crimp with a ratchet tool sized for 10-12 AWG; the common error is leaving a gap between insulation and barrel, which lets the wire pull out under vibration.

Will the yellow vinyl insulation on these 250 series terminals degrade and need replacement?

The vinyl insulation is rated to 221 degrees F and carries UL and CSA listings; it does not require periodic replacement unless physical damage, cracking from heat cycling, or chemical exposure compromises the partial coverage.

At what current level does the .032 in. brass tab on these 600 V disconnects become the limiting factor during sustained loads?

The .032 in. thick brass tab with tin finish and .25 in. width sets the ampacity limit; sustained current near the 10-12 AWG conductor rating will heat the tab first, so size the circuit breaker to the wire gauge, not the disconnect alone.
