Sta-Kon 14RB-2577L VNYL FLLY INS FEM DISC 16-14 BLUE

The 14RB-2577L is sized for 16-14 AWG stranded or solid conductor. That is the blue color code band, so if you have blue barrels already in the panel, this is the same wire range. For 22-18 AWG you need a red-coded terminal and for 12-10 AWG a yellow one.

Female. It is the receptacle half that slides onto a male tab, so it is the end you put on the wire running to a spade terminal on a motor, switch, thermostat or relay. If you need the mating blade side, order a male disconnect instead.

It is a fully insulated vinyl disconnect, meaning the vinyl sleeve covers the crimp barrel and extends over the tab body rather than stopping at the barrel. That is what you want where terminals sit close together on a switch or relay and you need to keep adjacent tabs from shorting. If your application calls for a bare or partially insulated quick disconnect, this is not that part.

The 14RB-2577L uses vinyl insulation. Vinyl is the standard choice for general control and appliance wiring and it is more flexible, but nylon insulated disconnects take higher heat and resist abrasion and cut-through better. For rooftop units, motor junction boxes, or anywhere the terminal sits near a heat source, specify a nylon insulated female disconnect in the same 16-14 AWG range instead.

Insulated terminals like this one crimp with an insulated-barrel crimp die, not the bare-terminal nest on a combination tool. Sta-Kon terminals are designed around Thomas and Betts Sta-Kon hand tools, and using the wrong die on a fully insulated vinyl barrel will split the sleeve or leave an under-crimped joint. Match the die to the blue 16-14 AWG color band.

Country of origin on the 14RB-2577L is the United States. That matters if you are buying against a Buy American or domestic-preference clause on a government, school or healthcare job.
