The Siemens SENTRON 3VA1196-4EF36-0KC0 is a 3-pole molded case circuit breaker rated 16 A continuous at 40 °C, with a breaking capacity of 121 kA at 240 V AC and 75.6 kA at 415 V AC. Designed for line protection, not motor protection; it's the feeder breaker, not the starter. The auxiliary switches are wired into the control circuit, not the power path — they signal open/closed state without carrying load current.
The 16 A rating holds flat from 40 °C through 55 °C (–); at 60 °C it derates to 15 A, and stays at 15 A through 70 °C (–). That's a clean thermal curve — no surprise drop at 50 °C. The 10.6 W maximum power loss is the heat you need to vent inside the enclosure — at 16 A load, that's about what a small relay bank dissipates.
