The Siemens 3VA1196-5EF32-0BH0 is a 3-pole IEC frame 160 circuit breaker in the 3VA1 series, rated for breaking capacity class M with Icu=55kA at 415V. It carries a TM240 thermal-magnetic trip unit set at In=16A, with overload protection adjustable Ir=11A...16A and short-circuit protection Ii=10...20 x In.
For a 160A frame with a 16A TM240 trip, this is a high-interrupting variant (class M) suited for installations with high available fault current, such as industrial switchboards or transformer secondaries. The adjustable Ir (11-16A) lets you fine-tune the overload threshold to match the protected conductor or load without swapping the trip unit. The Ii range of 10-20x In means the magnetic instantaneous trip can be set between 160A and 320A, giving selectivity headroom downstream.
Deployment context
The UVR at 24V DC provides undervoltage release — if the control voltage drops, the breaker trips, which is typical for emergency-stop circuits or safety disconnects where loss of control power must open the main feeder.
