Siemens SENTRON 3VA2216-5MN32-0AH0 — 160 A MCCB with ETU350M
The interrupting capacity reaches 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 17 kA at 690 V — figures that define the available fault current it can safely clear at each system voltage without upstream coordination changes.
Rated continuous current holds at 160 A from 40 °C through 50 °C ambient; above that it derates to 153.6 A at 55 °C, 150.4 A at 60 °C, 147.2 A at 65 °C, and 144 A at 70 °C. The maximum power loss at rated load is 75 W, which should be considered in enclosure thermal calculations. The latching endurance is rated at 20 000 cycles, which covers frequent switching in motor-starting or process-interlock applications.
