The Siemens SENTRON 3VA2116-5HL32-0AK0 is a 3-pole molded case circuit breaker (MCCB) with a continuous current rating of 160 A, flat across the entire operating temperature range from 40 °C to 70 °C — no derating needed up to the full 70 °C ambient. That's a hard spec for panel builders in hot enclosures or near process heat. The interrupting ratings are high: 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.
Front IP40 protection means it's suited for clean indoor panel environments, not washdown areas. The auxiliary switch complement — 1 auxiliary + 1 trip alarm + 1 electrical alarm switch — is built in, so you don't need a separate accessory module for remote status indication.
That's a compact 3-pole MCCB for the 160 A rating. Rated insulation voltage is 800 V, so it's suitable for 480/277 V and 600/347 V systems with headroom.
