The Siemens SENTRON 3VA2116-5HN32-0BA0 is a 3-pole molded case circuit breaker (MCCB) rated for line protection, carrying a continuous current of 160 A across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling. Interrupting capacity hits 187 kA at 240 V AC, dropping to 121 kA at 415/440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V.
That 105 mm width for a 3-pole 160 A frame is standard for SENTRON 3VA2 — it slots into existing panel layouts without re-drilling the mounting plate. Depth of 86 mm leaves room for rear bus connections and cable bends in a typical 600 mm deep enclosure.
