The Siemens SENTRON 3VA2216-7JP42-0AA0 is a 4-pole molded case circuit breaker (MCCB) rated for 160 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling. That flat thermal curve is unusual; most breakers start pulling back above 40 °C. Breaking capacity is the headline: 330 kA at 240 V AC, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 4.5 kA at 690 V. The 690 V rating drops to 4.5 kA, which still covers most industrial distribution faults at that voltage level.
