The Siemens 3VA1116-6EF32-0CC0 is a 3-pole IEC frame 160 molded-case circuit breaker in breaking capacity class H, rated Icu=70kA at 415V AC. That 70kA interrupting rating means it handles high fault currents typical in industrial distribution — no cascading upstream breakers needed at that level. The TM240 thermal-magnetic trip unit gives adjustable overload protection from 112A to 160A (Ir) and short-circuit pickup (Ii) from 5 to 10 times In, so you dial in the protection curve for the load, not the other way around.
For selectivity studies, you compare this with the upstream device's let-through: a 70kA rating at 415V gives solid headroom for most secondary distribution panels. The TM240 trip is line-protection (not motor-protection) so it's sized for cable and busbar protection, not for overload relay coordination on a motor starter. Two HQ auxiliary switches give status feedback to the PLC or annunciator panel.
Deployment context
The UVR and aux switches are factory-integrated; no field wiring of add-on modules. Typical placement: main incoming breaker in a 160A-rated sub-distribution board or as a feeder breaker in a motor control center bucket.
