The 3VA9773-0JJ64: Strip length is specified at 1.34–1.78 in, depending on which hole in the terminal block you land the conductor into. That range covers both the smaller and larger barrel openings — land the conductor so the stripped portion seats fully inside the compression zone without bare copper showing past the insulator.
It accepts stranded copper or aluminum from 1/0 AWG minimum up to 750 kcmil maximum.
It is designed for 3-pole 3VA57, 3VA58, 3VA67, and 3VA68 circuit breakers.
The part is sourced and quoted to order against an RFQ through independent distribution, with availability and current pricing confirmed at quote time.
