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. It carries the ETU320 electronic trip unit, which means adjustable overload and short-circuit protection curves rather than fixed thermal-magnetic response. 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. That 187 kA figure at 240 V covers most North American high-fault panelboard applications without needing a current-limiting upstream breaker.
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.
Physical footprint: 86 mm deep, 105 mm wide, 181 mm tall. That's a compact 3-pole MCCB for the 160 A rating. Mounts on a DIN rail or panel-mount plate. The 86 mm depth is the dimension to check for enclosure depth clearance — it's shallower than many older-frame MCCBs at this ampacity. Rated insulation voltage is 800 V, so it's suitable for 480/277 V and 600/347 V systems with headroom. No undervoltage release, no ground-fault monitoring, no communication module on this variant — it's a straight thermal-magnetic replacement with electronic trip adjustability.
