This Siemens SENTRON wire connector, model 3VA9243-0JC22, is an accessory for the 3VA6 150/250 circuit breaker series. It is designed as a circular conductor terminal, enabling connections for two cables along with a control wire voltage tap-off.
The connector supports a wide range of conductor sizes, accommodating both copper and aluminum stranded or finely stranded cables. According to IEC standards, it can handle conductor cross-sections from a minimum of 25 mm² to a maximum of 150 mm², with a stripped length requirement of 26 to 51 mm. The recommended tightening torque for copper cables in this range is 31.1 Nm.
Under UL standards (UL 486A-486B), the permissible temperature for connectable conductors is 75 °C. The stripped length requirement 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 both stranded and finely stranded copper or aluminum cables. The tightening torque for these connections is specified as 275 lb-in.
This accessory is part of the SENTRON product line, known for its reliability in power distribution and low voltage switchgear applications. It is supplied as a unit of 3 accessory units.
