That's serious fault-current headroom for a 160 A frame — it'll clear a bolted fault upstream of a motor starter without the arc flash escalating. At 440 V it's still 30 kA, enough for most 480 V distribution panels in North America. Out here in the grease, what matters is whether this thing handles the heat a motor panel sees. Past that it starts to derate — 153.6 A at 55 °C, 150.4 A at 60 °C, down to 144 A at 70 °C (-). ## Panel fit and auxiliary contacts Front-facing IP40 protection keeps dust and accidental tool contact out of the mechanism.","metaTitle":"Siemens 3VA1216-5MH32-0AG0 SENTRON MCCB, 160 A, 187 kA","metaDescription":"Siemens SENTRON 3VA1216-5MH32-0AG0 molded case circuit breaker, 160 A rated, 187 kA at 240 V, 3-pole starter protection with TM120M release.
