Sta-Kon F2029 INS PP FERRULE 18-17, 1 MM2, LG .6

The F2029 wire ferrule is sized for 18-17 AWG conductor, which is the 1 mm2 metric equivalent called out in the part description. If you are terminating 16 AWG or larger stranded wire, you need a larger ferrule in the series, not this one.

Red is the insulation color on the F2029, and on ferrules the collar color is how you identify the wire size at a glance after the fact. Red on this part corresponds to the 1 mm2 / 18-17 AWG size. Handy on a panel where a dozen sizes are in use and you need to confirm the right ferrule was crimped without pulling the conductor.

A crimped ferrule like the F2029 gathers the strands of a 1 mm2 / 18-17 AWG conductor into a solid pin so the terminal screw clamps the whole bundle instead of splaying strands out of the block. That is why panel builders use them on every stranded landing. For solid conductor it adds nothing. The F2029's barrel is copper, so it crimps and conducts like the wire it is replacing at the clamp point.

The F2029 is a polypropylene insulated ferrule, meaning the copper barrel has a molded plastic collar on the entry end. The collar funnels the strands in, gives the crimp tool a defined stop, and keeps the strip length covered where it exits the terminal. A bare ferrule has no collar, so it crimps shorter overall but leaves exposed strand at the transition. In dense control cabinets the insulated version is the normal choice.

Germany is the country of origin on the F2029 ferrule. Worth noting for public and institutional procurement where origin has to be declared on the submittal.
