What this 3VA1 breaker carries
The Siemens 3VA1196-6GF42-0AA0-ZD00 is a 4-pole IEC frame 160 circuit breaker in the H breaking capacity class, rated to interrupt 70 kA at 415 VAC. The TM240 thermal-magnetic trip unit is set for a 16 A nominal rating (In), with overload protection adjustable from 11 A to 16 A (Ir) and short-circuit pickup (Ii) at 10 to 20 times In. The N conductor is protected at 100% — full-rated, not reduced — which is the right call for a 4-wire system where the neutral carries phase imbalance or harmonics.
If you're matching an existing BOM line, verify the accessory kit and any factory-set parameters against your panel drawing before committing the order.
Four-pole construction at frame 160 takes up the standard 4-module width; plan your DIN rail fill factor accordingly. The TM240 trip unit is field-adjustable, so you can dial Ir and Ii without swapping the entire breaker — handy if the load changes during commissioning.
