The Siemens SENTRON 3VA9244-0JG12 is a wire connector accessory — specifically the TA1.4 lug with an integrated control-wire voltage tap-off — designed for the 3VA6 150/250 frame molded-case circuit breakers. It comes as a pack of four units, so one order covers a three-pole breaker plus a spare. The connector accepts copper stranded and finely stranded conductors from 6 AWG up to 350 kcmil. For aluminum, it handles solid wire at exactly 16 mm² and stranded aluminum from 6 AWG to 350 kcmil. The wire stripping length is 0.8 in.
Terminal markings and compliance
The terminal carries a UL marking of TA1.4 CMC 6-350 CU7AL UR CSA, confirming UL recognition for copper and aluminum conductors in that range, plus CSA acceptance. The IEC marking reads 16-185 mm² CU/AL NNL, which covers the metric range for copper and aluminum. These dual markings mean the same lug is panel-acceptable in North American and IEC-spec installations without swapping hardware.
