The Siemens SENTRON 3VA2116-8JP32-0AA0 is a 3-pole molded case circuit breaker (MCCB) rated for 160 A continuous current with an ETU550 electronic trip unit — the same trip platform used across the 3VA2 line for adjustable thermal-magnetic and LSI protection curves. The 440 kA interrupting rating at 240 V and 330 kA at 415 V mean this breaker can sit at the main or a high-fault subfeed without cascading upstream, even on a 400 V industrial service where available fault current runs high.
What the ratings mean for fit
The 160 A rating holds flat across the full ambient range from 40 °C to 70 °C — no derating curve to calculate for a warm panel. That is rare in this frame size; most MCCBs start shedding amps above 40 °C. The ETU550 is a communicating trip unit, so the breaker can report load current and alarm status over the SENTRON communication bus — useful for a BMS or SCADA tie-in without adding a separate current transformer. The 86 mm depth and 105 mm width fit a standard 3-pole MCCB footprint on a DIN rail or panel-mount base; the 181 mm height clears most 200 A switchgear enclosures without a gutter extension.
