The Siemens SENTRON 3VA2116-6HN32-0CH0 is a 3-pole molded case circuit breaker rated for 160 A continuous current across the full 40 °C to 70 °C ambient range — no derating needed as the panel warms up. Breaking capacity steps from 242 kA at 240 V down to 187 kA at 415 V and 440 V, then 121 kA at 500 V, and 3.7 kA at 690 V. That's a lot of fault-interrupting headroom for a 160 A frame; you're buying selectivity margin on the high side, not a breaker that's maxed out at its first fault.
Built-in extras that matter on the line
No communication function onboard; this is a hardwired breaker, not a smart metering unit.
