3VA9473-0JJ23 -  2-barrel, 3P Lug Kit - 3VA53/63

If you’re working with larger conductors and tight panel space, you already know how important a clean, secure termination is. The Siemens 3VA9473-0JJ23 wire connector kit is built for exactly that—giving you a dependable way to connect two cables per terminal without compromising performance. This connector is part of the SENTRON 3VA series accessory line, designed to match up perfectly with Siemens 3VA5 and 3VA6 circuit breakers. It handles a wide range of conductor sizes—from 2/0 AWG up to 600 kcmil—so you’re not stuck trying to force a one-size-fits-all solution into a job that clearly isn’t. What makes this piece stand out is how it simplifies the install. Instead of fighting with multiple lugs or awkward routing, you get a straightforward dual-cable connection that keeps things organized and solid. Once tightened to spec, it holds firm, giving you the kind of connection you don’t have to second-guess later.
