This Siemens wire connector, part number 3VA9243-0JC13, is an accessory designed for use with the 3VA6 150/250 circuit breaker series. It functions as a terminal block for connecting conductors.
According to IEC standards, this connector can accommodate stranded copper or aluminum cables with cross-sections ranging from a minimum of 50 mm² to a maximum of 240 mm². The required stripped length for these connections is 30.5 mm. For copper cables, the tightening torque is specified at 31.1 Nm for both stranded and finely stranded conductors within the 50-150 mm² range.
Under UL standards, the permissible temperature for the connectable conductor is 75 °C. The connector supports stranded and finely stranded copper cables from 2 AWG to 350 kcmil, and stranded aluminum cables from 2 AWG to 350 kcmil. The stripped length for UL connections is 1.2 inches. Tightening torque for copper cables under UL specifications is 275 lb-in for both stranded and finely stranded conductors in the 2 AWG to 350 kcmil range.
This accessory is identified by the DK Part Number 3473-3VA9243-0JC13-ND.
Per IEC, the connector accepts stranded copper or aluminum conductors from 50 mm² to 240 mm². Per UL, it accepts 2 AWG to 350 kcmil (copper or aluminum).
The stripped length is 30.5 mm per IEC or 1.2 in per UL.
For copper cables (stranded or finely stranded) from 50-150 mm² (IEC) or 2 AWG - 350 kcmil (UL), the tightening torque is 31.1 Nm (275 lb-in).
The maximum permissible temperature for the connectable conductor is 75°C according to UL 486A-486B.
The connector supports stranded copper and aluminum cables, including finely stranded copper cables.
