Each terminal accepts four cables in the 4/0 AWG to 600 kcmil range for both copper and aluminum stranded conductors, with a termination torque of 42.4 Nm for 120–300 mm² stranded and 120–185 mm² finely stranded copper. The voltage tap-off lets you pick up control power directly at the breaker line terminals — no separate tap block needed, which saves a DIN-rail position and one wiring step during panel build. ## Wire range and termination Strip length is 0.9 / 1.75 in depending on conductor type. The 42.4 Nm torque spec applies across the full stranded and finely stranded copper range; aluminum conductors in the same 4/0–600 kcmil range terminate at the same torque, so no re-torque step is needed when switching material on the same breaker.","metaTitle":"Siemens 3VA9673-0JC44 SENTRON Wire Connector, 4/0-600 kcmil,","metaDescription":"Siemens SENTRON 3VA9673-0JC44 wire connector TA4.4 with control-wire voltage tap-off.
