This Siemens 3VA9233-0JJ22 is an accessory terminal block, specifically a wire connector, designed for integration with the 3VA5 250 circuit breaker series.
It facilitates connections for both copper and aluminum stranded conductors, accommodating sizes from a minimum of 4 AWG up to 300 kcmil (or 25 mm² to 150 mm² according to IEC standards). The required stripped length for connections ranges from 1 to 2 inches (26 to 51 mm).
Installation involves specific tightening torques to ensure secure connections. For copper cables, the recommended torque is 275 lb-in (UL) or 31.1 Nm (IEC) for stranded and finely stranded conductors within the specified ranges. The permissible conductor temperature according to UL 486A-486B is 75 °C.
