The Siemens 3VA9603-0JJ35 is a SENTRON TA5.2 circular conductor terminal — a wire connector rated for 30 Nm tightening torque across solid, stranded, and finely stranded copper or aluminum conductors. It accepts cables from 300 kcmil minimum up to 600 kcmil maximum, with a stripped length of 1.50/2.64 inches. This is a 3-unit pack of connectors designed as accessories for the 3VA9603-0KP00 plug-in unit.
The 30 Nm torque rating is the key installation parameter — it governs the mechanical and electrical integrity of the connection. Under-torque risks loose termination and heating; over-torque can damage the conductor or the connector body. The 300-600 kcmil range covers large mains and feeder cables typical in panel-to-busbar or transformer connections. The stripped length of 1.50/2.64 inches gives the wireman a clear target for strip preparation, avoiding exposed conductor past the terminal.
The 3VA9603-0JJ35 is an active, current-production part per Siemens lifecycle status.
