3VA9473-0JE23 -  2-barrel, 3P Lug Kit - 3VA53/63

If you’re working with high-capacity circuit breakers, you already know this—the connection point is everything. A weak or poorly fitted connector can compromise the entire system. That’s where the Siemens 3VA9473-0JE23 wire connector (TC2.4) comes in. Built specifically for SENTRON 3VA5 and 3VA6 circuit breakers (400–600 frame), this connector gives you a secure, high-performance way to terminate large copper conductors from 2/0 AWG up to 600 kcmil. It’s designed to handle serious load demands while keeping installation straightforward and reliable. With the ability to accommodate two cables per terminal, it’s a practical solution when you need flexibility without sacrificing connection integrity. What makes this connector stand out is its balance of precision fit, strong clamping force, and thermal stability. Once installed and torqued to spec, it holds tight—reducing the risk of loosening, overheating, or performance issues over time. That’s exactly what you want when downtime isn’t an option.
