Sta-Kon F9038 NON-INS FERRULE 1/0, 50 MM2, LG .98

The F9038 ferrule is sized for 1/0 AWG conductor, which is the 50 mm2 metric equivalent. If you are terminating 2 AWG or 2/0, this is the wrong barrel size, pick the ferrule matched to that cross section instead. Crimping an oversized ferrule leaves the strands loose in the barrel and the connection will heat up under load.

Yes. The F9038 is covered under UL file E489056, which is the number an inspector or submittal reviewer will want cited for the termination.

No. The F9038 barrel is copper and is intended for copper stranded conductor. Aluminum terminations need a connector rated AL or AL9CU with the appropriate inhibitor compound, so use a dual-rated lug or ferrule for that work instead.

It is a non-insulated ferrule, a bare copper barrel with no plastic collar. That means no color-coded insulation to identify the size once it is crimped, and no strain relief at the wire entry, so you rely on the terminal block or your own sleeving for insulation. Where a panel builder wants color coding by cross section, an insulated ferrule is the better choice.

A 1/0 / 50 mm2 ferrule is beyond the range of the small hand ferrule crimpers used for control wiring. A barrel this size needs a heavy hex or four-indent crimp tool with a die matched to 50 mm2. Using an undersized trapezoid die on a .98 inch copper barrel will not develop a full crimp across the length.

Germany. That matters on public or institutional jobs where country of origin has to be declared on the submittal, so you can state DE for this part without chasing the vendor.
