Sta-Kon RA3RR – Frequently Asked Questions
1) What wire gauge does the Sta-Kon RA3RR ring terminal accept?
The RA3RR is sized for conductors of 0.5 to 1.5 mm2. In AWG terms that covers roughly 22 through 16 gauge stranded wire, the small control and signal wiring range. Anything heavier than 1.5 mm2 needs the next barrel size up, not this one.
2) What stud or screw size does the Sta-Kon RA3RR ring fit?
It is an M3 ring, so the tongue is drilled for a 3 mm screw or stud, the usual terminal block and small panel screw size. If your terminal strip uses M4 or a #8 stud, the RA3RR ring will not pass over it.
3) Is the insulation on the Sta-Kon RA3RR nylon or vinyl?
Neither. The RA3RR uses a polycarbonate insulating sleeve, which is a rigid thermoplastic rather than the soft PVC found on common vinyl terminals. That matters if you are specifying terminals for a panel where the insulation has to hold its shape under heat and handling.
4) Should I use a ring terminal or a spade terminal on my control panel terminal blocks?
A ring like the RA3RR has a closed tongue, so the connection cannot pull off the stud unless the screw is fully removed. That is what you want on vibration-prone equipment and on anything where a dropped conductor is a safety issue. A spade (fork) terminal slides out under a loosened screw, which is faster for maintenance but less secure. For an M3 terminal screw with 0.5 to 1.5 mm2 wire, the RA3RR is the closed-tongue choice.
5) Why is the Sta-Kon RA3RR red, and does the color mean anything?
Red is the standard color code for the small insulated terminal range, and on the RA3RR it corresponds to the 0.5 to 1.5 mm2 wire barrel. Panel builders use that color to confirm at a glance that the right barrel size went on the right conductor during inspection.
6) What exact part number do I order for the Sta-Kon M3 polycarbonate insulated ring, and where is it made?
Order it as Sta-Kon RA3RR. That is the single orderable model, a red polycarbonate insulated ring terminal for M3 studs, manufactured in Sweden.
