Frequently asked questions
What wire sizes does 3VA9603-0JC43 accept?
It accepts stranded copper or aluminum cable from 4/0 AWG minimum to 500 kcmil maximum, with a termination torque of 325 lb-in. Finely stranded conductors in the same range use the same torque value.
What is the stripped length for this connector?
The stripped length range is 0.91 to 1.75 inches. Set your wire stripper within that band to ensure full conductor insertion under the lug.
What does the control wire tap do on 3VA9603-0JC43?
The control wire tap provides a voltage take-off point for feeding a shunt trip, undervoltage release, or auxiliary device without a separate splice block. It is integrated into the connector body.
