This Siemens SENTRON wire connector, part number 3VA9133-0JC18, is an accessory designed for use with 3VA4/5 125 circuit breakers. It facilitates connections for two cables and includes a control wire tap and an extended terminal cover with probe holes for voltage testing.
The connector is suitable for copper and aluminum stranded conductors, supporting a minimum cross-section of 25 mm² and a maximum of 150 mm². The stripped length required is 30.5 mm. For copper cables, the specified tightening torque is 28.5 Nm for both stranded and finely stranded conductors within the 25-150 mm² range.
According to UL standards, the connectable conductor cross-section ranges from 4 AWG to 300 kcmil for stranded and finely stranded copper conductors, and 4 AWG to 300 kcmil for aluminum stranded conductors. The permissible temperature for the connectable conductor, as per UL 486A-486B, is 75 °C. The stripped length for UL connections is 1.2 inches. The tightening torque for UL connections using copper cables (stranded or finely stranded) is 252 lb-in for conductors ranging from 4 AWG to 350 kcmil.
This accessory comes in a package of 3 pieces and includes a terminal cover. It is compatible with Siemens 3VA4 and 3VA5 series circuit breakers rated at 125A.
The connector supports a maximum conductor cross-section of 150 mm² for copper and aluminum stranded cables according to IEC standards, and up to 300 kcmil according to UL standards.
