Sta-Kon RB2573M – Frequently Asked Questions

1) What does the blue color on a Sta-Kon RB2573M disconnect indicate about wire size?
Blue is the standard color code for 16-14 AWG insulated terminals, and the Sta-Kon RB2573M carries blue nylon/polyamide insulation. Use the color to sort your terminals on the panel bench: blue for 16-14 AWG, red for 22-18, yellow for 12-10. Crimp it with the blue die position on an insulated terminal tool.
2) What is a 250 flag terminal and when would I use one instead of a straight female disconnect?
A .250 flag disconnect puts the receptacle at a right angle to the wire instead of in line with it, so the wire exits sideways off the tab. That is what you want when the spade on the device sits close to a panel wall, a motor housing, or another component and a straight push-on body would not clear it. If you have room behind the tab, a standard in-line .250 female disconnect is the simpler pick. The RB2573M is the flag version, fully insulated.
3) Is this terminal UL listed for use in a control panel?
The Sta-Kon female disconnect is listed under UL file E66716, which is what an inspector or a panel shop QC file wants to see on an insulated crimp terminal. That listing is stated on the product's standards data.
4) Are these disconnects made in the USA? We have domestic-content requirements on government work.
The Sta-Kon RB2573M is manufactured in the United States. That matters on federally funded and Buy American projects where crimp terminals count toward the electrical material content.
5) Is the barrel brass or steel, and does that matter for marine or outdoor equipment?
Brass. The conductive body of this fully insulated female disconnect is brass, which gives you better conductivity and more corrosion resistance than a plain steel terminal, so it holds up better in marine panels, outdoor HVAC units and damp mechanical rooms. The nylon/polyamide sleeve covers the barrel completely, so there is no bare metal exposed once crimped.
6) What is the exact part number I should order for the Sta-Kon blue 250 flag female disconnect?
Order Sta-Kon RB2573M. That is the single model for this fully insulated nylon blue .250 flag female disconnect, so there is no size or finish to specify beyond the part number.
7) Does fully insulated mean I don't need heat shrink or boots over the connection?
The nylon/polyamide insulation on the RB2573M covers both the crimp barrel and the receptacle body, so the connection is shielded from accidental contact without adding a separate boot. Nylon also takes a crimp without cracking the way vinyl can, which is why it is the usual spec for panel and appliance work.
