This Siemens SENTRON accessory, part number 3VA9233-0JG12, functions as a wire connector with control wire voltage tap-off. It is specifically designed for use with the 3VA5 250 circuit breaker series.
The connector facilitates connections for copper and aluminum cables, supporting stranded and solid configurations. According to IEC standards, it accommodates conductor cross-sections ranging from a minimum of 16 mm² to a maximum of 185 mm². The required stripped length for connections is 20 mm.
For copper cables, tightening torques vary based on conductor size and stranding. For solid 16 mm² conductors, the torque is 15.8 Nm. For stranded conductors between 16-35 mm², the torque is also 15.8 Nm, while larger stranded conductors from 50-185 mm² require 31.1 Nm. Similar torque specifications apply to finely stranded copper cables.
UL standards also define conductor cross-section compatibility, with minimums and maximums of 6 AWG and 350 kcmil for stranded and finely stranded copper and aluminum cables. Permissible conductor temperature according to UL 486A-486B is 75 °C. The stripped length for UL connections is 0.8 inches.
