Sta-Kon RA2573 – Frequently Asked Questions

1) Will the Sta-Kon RA2573 female disconnect fit a 1/4 inch male tab?
Yes. The RA2573 is a female quick-disconnect sized for 0.250 inch (1/4 inch) male tabs, which is the common tab size on switches, relays, HVAC contactors and blower motors. Push it straight on for full engagement; the nylon body covers the tab shoulder once seated.
2) What wire gauge does the Sta-Kon RA2573 red disconnect crimp onto?
It is a 22 AWG terminal. Red insulation on Sta-Kon disconnects is the small-wire color code, and this one is built for 22 gauge conductor. If you are terminating 16 to 14 AWG you need a blue or yellow barrel instead, not this red one.
3) Is the Sta-Kon RA2573 UL listed for panel and control wiring?
It carries UL file E66716. That covers the terminal itself for electrical safety compliance, which is what an inspector or a spec writer on a control panel or institutional MRO job will be looking for.
4) Is this female disconnect fully insulated or just vinyl sleeved?
Fully insulated, with a nylon/polyamide body rather than a loose vinyl sleeve. The nylon shroud covers the barrel and the tab receptacle, so there is no exposed metal once the terminal is seated on the tab. Nylon also holds up better to heat and crimp pressure than vinyl, which is why it gets specified in control panels and HVAC circuits where terminals sit close together.
5) What is the terminal barrel made of, and will it hold up in a humid or outdoor enclosure?
The conductor barrel is brass, which gives good conductivity and resists corrosion better than plain steel. Combined with the nylon body it is a reasonable choice for HVAC control circuits and equipment enclosures. For direct water exposure you would want a heat-shrink sealed disconnect instead, since this one is not a sealed terminal.
6) Do I need a special crimper for Sta-Kon nylon insulated disconnects?
Use an insulated-terminal crimper matched to the red 22 AWG range, not a bare-terminal or plier-style tool. Strip the wire, bottom it in the barrel before crimping, then tug-test the finished crimp. A bare-metal die will crush the nylon body and leave you with a connection that pulls out.
7) Is the RA2573 made in the USA?
Yes, country of origin is the United States. That matters on government, healthcare and other publicly funded jobs where domestic sourcing is part of the procurement spec.
8) How many terminals come in a pack of the Sta-Kon RA2573?
The RA2573 red 22 AWG female disconnect is supplied as a 1,000 piece pack, which is the normal buy for a panel shop or an MRO crib standardizing on one terminal rather than a job-count handful.
