Sta-Kon RA2577F – Frequently Asked Questions
1) What wire size does the Sta-Kon RA2577F flag disconnect crimp onto?
The RA2577F takes 22-18 AWG stranded wire, which is why the insulation is red. Red is the standard color code for the 22-18 AWG range on insulated terminals, so if you are matching to a crimper with color-coded dies, use the red nest.
2) Will the RA2577F fit a 1/4 inch male tab on a motor or relay?
Yes. It is a FEM-250 female disconnect, meaning it slides onto a 0.250 inch (1/4 inch) wide male blade tab, the common tab size on motors, relays, switches and HVAC components.
3) What does the 90 degree flag shape on this disconnect actually do for me?
The flag style brings the wire in at a right angle to the tab instead of straight on, so the conductor lays flat along the component rather than standing proud of it. That is what gets a terminal into a shallow junction box, a crowded contactor stack, or behind a panel cover where a straight disconnect would bottom out. A straight female 250 disconnect is the one to use when you have room in line with the tab.
4) Is the Sta-Kon RA2577F UL recognized?
It carries UL file E66716. That is the listing reference to quote when an inspector or a submittal package asks for the terminal's UL identification.
5) What is the RA2577F made of, and will the nylon hold up better than vinyl?
The terminal body is brass with nylon/polyamide insulation. Nylon takes abrasion and higher heat better than PVC/vinyl insulation and resists cracking when the terminal is flexed onto a tab, which is why it is the usual choice for equipment and appliance wiring rather than general low-duty work.
6) What is the open top design on this flag disconnect for?
Open top means the crimp barrel is visible through the insulation opening, so you can see the conductor seated in the barrel before and after you crimp. On inspected work that visual check is the fastest way to prove the wire was fully inserted and not crimped on insulation.
7) Is the Sta-Kon RA2577F made in the USA for a government or Buy American job?
Country of origin is the United States. For a federal or institutional spec that requires domestic content documentation, that is the origin on record for the RA2577F.
8) What part number do I order for this red 22-18 AWG flag disconnect?
Order it as Sta-Kon RA2577F. That single model number covers the red nylon insulated open top 90 degree flag female 250 disconnect for 22-18 AWG wire, so there is no finish or size option to specify.
