Sta-Kon RB2573 – Frequently Asked Questions

1) What wire size does the Sta-Kon RB2573 female disconnect crimp onto?
The Sta-Kon RB2573 is sized for 16 AWG conductors, and the blue insulation is the standard color code for the 16 to 14 AWG range. If you are terminating 18 to 22 AWG, you need a red-barrel disconnect instead; for 12 to 10 AWG, a yellow one. Crimping 16 AWG terminal onto undersized wire gives you a connection that pulls out under vibration.
2) Is the insulation on this disconnect nylon or vinyl, and does it matter in a hot panel?
Nylon/polyamide, not vinyl. Nylon barrels resist crushing and abrasion better during pull-through and hold up to higher operating temperatures than PVC-insulated terminals, which is why they are the usual choice for industrial control panels and HVAC control wiring. The insulation is full length over the barrel, so there is no exposed metal behind the crimp.
3) Are these Sta-Kon disconnects UL recognized for panel work?
They carry UL file E66716. That is the only standard stated for the RB2573, so if your spec calls out a particular temperature or voltage rating, verify it against that file rather than assuming it.
4) Do I need a special crimp tool for these nylon insulated disconnects?
Use an insulated-terminal crimper with the blue (16-14 AWG) nest. The nylon barrel is crimped through the insulation, so a bare-terminal or pliers-style crimp will split the nylon and leave an unsupported joint. No separate insulating sleeve is needed, the terminal is fully insulated as supplied.
5) Is the terminal body brass or steel, and will it hold up in a marine or outdoor enclosure?
The barrel and contact are brass, which gives better conductivity and corrosion resistance than plated steel. That is why the same part gets used in marine and automotive wiring as well as dry indoor panels. In salt-spray service, still seal or boot the connection.
6) How many disconnects come in a pack, and is this a bulk buy for a shop or truck stock?
The RB2573 is packaged 1,000 pieces, which is a shop or panel-build quantity rather than a small repair pack. Procurement groups standardizing one 16 AWG female .250 disconnect across a facility usually buy at this count.
7) Are Sta-Kon RB2573 terminals made in the USA?
Yes, country of origin is the United States, which matters if your job carries a domestic-sourcing or Buy American requirement on electrical components.
