This Siemens 3VA9234-0JC22 is a wire connector accessory, specifically a terminal block, designed for use with the 3VA5 250 circuit breaker series. It supports 2 cables with control wire voltage tap-off functionality.
The connector is engineered to handle a wide range of conductor sizes. According to IEC standards, it accepts copper or aluminum stranded conductors with cross-sections from a minimum of 25 mm² to a maximum of 150 mm². The required stripped length for these connections is between 26 mm and 51 mm. For copper cables within this range, the recommended tightening torque is 31.1 Nm for both stranded and finely stranded conductors.
Under UL standards (UL 486A-486B), the permissible temperature for the connectable conductor is 75 °C. The stripped length for UL connections is 1.0 to 2.0 inches. The connectable conductor cross-section ranges from a minimum of 4 AWG to a maximum of 300 kcmil for copper (stranded and finely stranded) and aluminum (stranded) cables. The tightening torque for these connections is specified as 275 lb-in for both stranded and finely stranded copper cables.
