It carries a 70 kA Icu breaking capacity at 220/240 V AC (50/60 Hz) per IEC 60947-2, stepping down to 36 kA at 380–440 V AC.
The 160 A TM-D trip is fixed long-time pickup at 1× In, so no adjustment dial — you're locked to the nameplate rating. That suits a dedicated feeder or a fixed-load panel where you don't need field tweaking. Thermal-magnetic protection covers overload (thermal) and short-circuit (magnetic) in one block; the magnetic instantaneous trip is factory-set and non-adjustable. Below 380 V you still get 36 kA, which covers most European 400 V distribution. Rated insulation voltage (Ui) is 690 V, and operational voltage (Ue) tops at 440 V AC. That 690 V Ui means the internal clearances are good for 690 V systems, so the breaker can sit in a 400/690 V panel without derating the insulation.
