This Siemens 3VA9243-0JJ22 is a circular conductor terminal accessory, specifically a wire connector, designed for use with 3VA6 150/250 circuit breakers. It facilitates secure connections for various conductor types and sizes.
According to IEC standards, this terminal can accommodate stranded copper or aluminum cables with cross-sections ranging 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. The tightening torque for copper cables within this range is specified as 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 connectable conductor cross-section for copper cable, both stranded and finely stranded, ranges from a minimum of 4 AWG to a maximum of 300 kcmil. For aluminum cable, the range is also from a minimum of 4 AWG to a maximum of 300 kcmil. The tightening torque for copper cables in the UL specification is 275 lb-in for both stranded and finely stranded conductors, with a stripped length of 1.0 to 2.0 inches.
