It accepts stranded copper or aluminum from 4/0 AWG up to 400 kcmil (225 A ampacity range) and finely stranded copper in the same range, making it a fit for feeder circuits where you need a control-wire takeoff without a separate terminal block. The stranded rating of 4/0 – 400 kcmil: 225 tells you the terminal body is sized for conductors that carry up to 225 A in typical 75 °C terminations — that's the ampacity of 4/0 copper at that temperature, so the tap won't become a bottleneck on a 200–225 A feeder. The 1.02 inch stripped length (about 26 mm) is the insulation removal you need for full contact in the compression saddle; less strip risks partial insertion, more leaves bare conductor exposed past the insulator. The control wire tap means there's a dedicated smaller terminal on the same connector body for a control-circuit takeoff — you land the power cables in the main saddle and run a smaller wire (typically 14–10 AWG) from the tap to a relay coil or PLC input, saving a separate tap block on the DIN rail. This accessory mounts directly onto the load-side lugs of a 3VA15 or 3VA25 molded-case circuit breaker (1000 A frame). It replaces the standard line/load lug kit when you need to split three outgoing cables into a voltage-tap point. The three-unit design handles three parallel conductors per phase — common on large feeders where a single 400 kcmil is too stiff to route, so you run two or three smaller cables in parallel.","metaTitle":"Siemens 3VA9503-0JG32 SENTRON TA3.2 Wire Connector, 3x 120-1","metaDescription":"Siemens 3VA9503-0JG32 SENTRON TA3.2 circular conductor terminal voltage tap.
