Terminal specs and fit
The Siemens SENTRON 3VA9504-0JG32 is a TA3.2 circular conductor terminal voltage tap — a wire connector accessory that lets you tap a control-wire takeoff from a main power cable. It accepts copper or aluminum stranded conductors from 4/0 AWG up to 400 kcmil (rated 225 A at that range), and finely stranded copper in the same gauge window. Three cables per terminal, each 120–185 mm² cross-section. Stripped length is 1.02 inches. The control-wire tap is integral — no separate splice needed.
This terminal mounts on the load side of a SENTRON 3VA15 or 3VA25 molded-case circuit breaker (1000 A frame). The voltage tap feeds a control circuit — say a panel light, contactor coil, or PLC power supply — without running a separate branch from the bus. Four units per pack; each unit handles one phase or neutral.
