ABB TNF10-250FD-XV – Frequently Asked Questions

1) What wire size does the ABB 250 Series yellow female disconnect take?
The ABB 250 Series fully insulated female disconnect is sized for 12-10 AWG conductors. The yellow insulator is the color code for that range, so a tech on a panel can confirm the right barrel at a glance instead of pulling out the spec sheet. If you are landing 16-14 AWG or 22-18 AWG, this is the wrong barrel and the crimp will not hold.
2) Which crimp tool should I use on the ABB TNF10-250FD-XV disconnect?
ABB calls out the WT112M and CM2000A crimping tools for this terminal. Using the matching die matters on an insulated barrel, because it compresses the metal sleeve and the nylon body together in one cycle. The barrel has internal serrations that bite the strands, and those only seat properly under a full, controlled crimp cycle.
3) What does fully insulated mean on this ABB disconnect, and do I still need heat shrink over it?
Fully insulated means the molded nylon/polyamide body covers the barrel and the connection point, with a metal insulation sleeve inside for mechanical support of the wire insulation. The design shields the termination from accidental contact and moisture intrusion on its own, so no additional sleeving is part of the assembly.
4) Should I use a nylon insulated disconnect or a vinyl one for machine and OEM wiring?
Nylon/polyamide, which is what the ABB 250 Series uses, is the tougher of the two insulators and holds up better to the abrasion and handling of OEM and machine wiring harnesses and control panel builds. Plain vinyl bodies are the cheaper choice for light general wiring. If the terminal is going into equipment wiring or a panelboard where it will be pulled, bundled, and re-dressed, the nylon body is the one to specify.
5) What is the exact part number for the ABB yellow 250 Series female disconnect?
Order it as ABB TNF10-250FD-XV. That is the 250 Series fully insulated nylon female disconnect in yellow for 12-10 AWG. Distributors cross-referencing should note the 250 designation refers to the tab series the terminal mates with, not the wire size.
6) Does the funnel entry on this terminal help with stranded wire?
That is exactly what it is for. The widened lead-in on the ABB 250 Series barrel guides stranded conductors in without fanning a strand outside the barrel, which is the usual cause of a bad crimp on 12-10 AWG stranded. Faster insertion in the field, and fewer terminations you have to cut off and redo.
