Torque spec is 30 Nm across all conductor types, with a stripped length of 1.50/2.64 inches. This is the accessory set for the plug-in unit 3VA9603-0KP00, not a standalone breaker or switch. Three TA5.3 connectors, each rated for 30 Nm on solid, stranded, and finely stranded conductors. No control-wire tap (no auxiliary tap terminal). The kit is complete for terminating four large cables per connector — no missing screws or brackets. ## Cable range and torque — what it means on the panel The 300–600 kcmil range (150–300 mm²) covers heavy feeder and main-bus connections common in 400 A to 800 A switchboards. A single torque value of 30 Nm across all conductor types simplifies installation — no need to adjust for solid vs. stranded vs. finely stranded. The stripped length of 1.50/2.64 inches gives enough insertion depth for a secure, low-resistance termination.","metaTitle":"Siemens 3VA9603-0JJ45 SENTRON Wire Connector, 30 Nm, 300-600","metaDescription":"Siemens 3VA9603-0JJ45 SENTRON wire connector, 30 Nm torque, 300-600 kcmil copper/aluminum, 3 units.
