What this breaker delivers
The Siemens SENTRON 3VA2216-6KP42-0AA0 is a 4-pole molded case circuit breaker (MCCB) rated for 160 A continuous current (Iu) across the full ambient range from 40 °C to 70 °C — no derating needed up to the top of that band. Its interrupting capacity hits 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 4.5 kA at 690 V — so the SCCR headroom is there for high-fault industrial distribution panels, not just light commercial mains.
