What this MCCB delivers
The Siemens SENTRON 3VA2216-8KP32-0AA0 is a 3-pole molded case circuit breaker rated for 160 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling. Interrupting capacity hits 440 kA at 240 V AC and still delivers 330 kA at 415 V and 440 V, dropping to 220 kA at 500 V and 52.5 kA at 690 V.
Integration and panel fit
Dimensions are 105 mm wide, 181 mm tall, 86 mm deep — standard 3-pole MCCB footprint for a 160 A frame. Front-side IP40 protection means it's fine in a clean indoor panel; keep the enclosure sealed if the cabinet sees dust or dripping water. The ETU850 includes a communication function (PROFIBUS or PROFINET via a separate communication module), so you can pull trip data, load profiles, and event logs into a PLC or SCADA without extra CTs.
The ETU850 release supports ground-fault monitoring as an option (this variant ships without it), but the communication function is built in, so you can retrofit a comms module later without swapping the breaker.
