3VA9233-0JJ22 -  2-barrel, 3P Lug Kit - 3VA52

If you’ve ever struggled to land large conductors cleanly inside a breaker, you already know—the connector matters just as much as the breaker itself. The Siemens 3VA9233-0JJ22 wire connector (TA2.3) is built to eliminate that headache, giving you a secure, straightforward way to terminate 4 AWG through 300 kcmil conductors on Siemens 3VA52 circuit breakers.

This isn’t some generic lug you “make work.” It’s purpose-built for SENTRON systems, which means everything lines up the way it should—fit, torque, and performance. Whether you’re working with copper or aluminum stranded cable, this connector delivers a tight, reliable hold with consistent conductivity. The dual-cable design also gives you flexibility in the field, saving time when configurations change or space gets tight.

From an installation standpoint, it’s simple: strip, land, torque, and move on—confident the connection will hold under load. From a performance standpoint, it’s exactly what you want—stable, compliant, and designed to handle demanding electrical environments without compromise.

If you're outfitting or maintaining a 3VA52 breaker setup, this is one of those small components that quietly makes a big difference.
