The Siemens SENTRON 3VA2116-5HL32-0JA0 is a 3-pole molded case circuit breaker (MCCB) rated for a continuous current of 160 A across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling. Its breaking capacity reaches 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V — covering high-fault utility feeds and transformer secondaries where available fault current is substantial.
Maximum power loss is 25.5 W — account for this thermal dissipation in the enclosure sizing, especially when grouping multiple breakers.
