The Siemens SENTRON 3VA2116-5HN36-0BA0 is a 3-pole molded case circuit breaker (MCCB) rated 160 A continuous at 40 °C, with an ETU350 electronic trip unit for line protection. The interrupting ratings are the headline: 187 kA at 240 V, 121 kA at 415 V and 440 V, 79 kA at 500 V, and 4.25 kA at 690 V. The 160 A rating holds flat to 50 °C; above that it derates to 154 A at 55 °C, 148 A at 60 °C, 142 A at 65 °C, and 136 A at 70 °C (–).
No auxiliary contact block is fitted; if you need signaling, add the separate auxiliary contact kit. The ETU350 is the overcurrent release — it's electronic, so it offers adjustable trip curves (long-time, short-time, instantaneous, ground fault) via the front dials. No communication function or phase failure detection on this variant. Power loss is 28 W max — factor that into enclosure thermal rise.
