3M MNU10-250DMIX Male Disconnects

The 3M MNU10-250DMIX is a pack of fifty yellow male quick-disconnect terminals designed for 12 to 10 AWG wire. Each connector uses a butted-seam copper barrel with tin plating and a nylon insulator that provides full coverage. They are CSA certified and UL listed for up to 600 volts.

Suited for crimped power connections

These disconnects suit installers who need a reliable crimp termination on 12 or 10 AWG conductors in automotive, marine or industrial wiring. They are not for smaller gauge wires below 12 AWG or larger cables above 10 AWG. Builders requiring a female mating tab or a different tab width should select an alternative part.

Nylon insulation handles sustained heat

The nylon insulation is rated to a maximum temperature of 221 degrees Fahrenheit, maintaining dielectric strength under continuous thermal load. Tin-plated copper contacts resist oxidation during long-term service. The butted barrel design delivers consistent mechanical grip after repeated mating cycles.

Questions about this item

What wire gauges must I already have to use these 12-10 AWG yellow male disconnects?

They accept solid or stranded copper wire from 12 AWG up to 10 AWG; anything outside that range will not crimp securely in the 0.15 in barrel.

Will the 0.032 in tab thickness and 0.187 in tab width fit the older blade terminals already in my harness?

Yes, the tab matches that exact thickness and width, so it mates with standard 0.187 in blade terminals of the same 0.032 in thickness.

After crimping, how can I confirm each disconnect is rated for the 600 V circuit I am wiring?

The yellow nylon insulation carries both UL Listed and CSA Certified markings, and the barrel is stamped for 600 V maximum, confirming the rating once installed.
