At 415 V, the 121 kA rating still covers most industrial transformer-fed busways. The thermal-magnetic TM120M release gives you a fixed thermal pickup at 160 A and a magnetic trip that responds to short-circuit currents. No electronic adjustability here — set it and forget it. If you need adjustable long-time or short-time delays, you'd be looking at the electronic trip variants in the 3VA family. An undervoltage release (UVR) is integrated as standard — the auxiliary trip module is order code 3VA9608-0BB11. No auxiliary contacts are fitted from the factory, so if you need status feedback to a PLC, you'll add them separately. Above that, it steps down: 153.6 A at 55 °C, 150.4 A at 60 °C, 147.2 A at 65 °C, and 144 A at 70 °C. Footprint: 105 mm wide, 158 mm tall, 70 mm deep. No special adapter brackets needed for most Siemens panelboards. ## Motor switching capability Rated operating power at AC-3 duty (400 V) is 55 W. That's not a motor-starting rating — it's the switching power for the auxiliary circuit. The breaker itself is a feeder protection device, not a motor starter. For motor branch circuits, pair it with a contactor and overload relay upstream or downstream as the coordination study dictates.","metaTitle":"Siemens 3VA1216-5MH32-0BA0 SENTRON MCCB, 160 A, 187 kA at 24","metaDescription":"Siemens SENTRON 3VA1216-5MH32-0BA0 molded case circuit breaker, 160 A rated, 187 kA breaking capacity at 240 V.
