It accepts four cables in the 120 to 300 mm² range, terminated at 42.4 Nm for both stranded and finely stranded copper, and the same torque for aluminum stranded up to 185 mm². ## Cable range and strip length For copper stranded cable, the terminal accepts from 4/0 AWG up to 600 kcmil; the same range applies to aluminum stranded and to finely stranded copper. The specified strip length is 0.9 / 1.75 in — that 0.9 in (about 23 mm) is for the smaller conductors in the range, the 1.75 in (44 mm) for the full 600 kcmil. No control-wire tap on this version (the TA4.4 is a straight power connector, not a tap-off block). Status is active per Siemens lifecycle data. No EOL notice, no NRND flag. This is a current-production accessory for the 3VA platform, so it can be specified into a BOM without worrying about last-time-buy windows.","metaTitle":"Siemens 3VA9603-0JJ44 SENTRON Wire Connector TA4.4, 4x120-30","metaDescription":"Siemens SENTRON 3VA9603-0JJ44 wire connector TA4.4 for 4 cables 120-300 mm².
