The Siemens 3VA9234-0JD11 is a wire connector TC1.3, supplied as a pack of 4 units, designed as an accessory for the 3VA52 molded case circuit breaker family. It accepts copper conductors from 14 AWG up to 1/0 AWG, covering the typical load-side and line-side termination range for 3VA52 frames in panel builds.
Panel integration note
Packaged dimensions of 150 x 100 x 22 mm per unit — these connectors are compact enough to store in a standard bin drawer alongside 3VA52 breaker trim kits. The TC1.3 designation indicates a tunnel-type lug with a clamping screw, suited for stranded or solid copper. Strip length and torque spec follow the 3VA52 terminal marking on the breaker itself.
