The Siemens 3VA9404-0JJ23 is a SENTRON TA2.4 circular conductor terminal — a wire connector designed for terminating large-gauge copper or aluminum cables in 3VA1 and 3VA2 molded-case circuit breaker feeders rated 400 A and 630 A. Each unit accommodates two cables of 70–300 mm² cross-section, and the order code ships as a 4-unit pack.
Cable fit and torque
Stripped length is 1.2 in for the smaller cable range and 2.3 in for the larger, matching the insertion depth of the TA2.4 barrel. No control-wire tap is integrated — this is a straight power terminal, not a combination lug.
Lifecycle and sourcing
For a BOM line that already qualifies the 3VA1 or 3VA2 breaker family, this terminal is the factory-recommended lug — no adapter plate or third-party cross-reference needed.
