160 A continuous, flat across the thermal range
The Siemens 3VA2216-5MN32-0HA0 is a SENTRON molded case circuit breaker (MCCB) rated for motor protection duty. It carries 160 A continuously from 40 °C through 70 °C ambient — no derating needed across that span, which simplifies panel design in a warm enclosure. Interrupting capacity is 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 4.5 kA at 690 V. That 187 kA figure at 240 V is the headline — it handles high available fault current on the secondary side of a distribution transformer without cascading upstream. The 3-pole unit is designed specifically for motor protection, with phase failure detection built in. It ships with a shunt trip (STL) auxiliary release; no auxiliary switch is fitted on this variant.
Footprint and panel fit
Dimensions are 105 mm wide × 181 mm high × 86 mm deep. That width is the standard 3-pole MCCB footprint for the SENTRON 3VA2 frame — it lands on a DIN rail or mounts directly to a backplate. The 86 mm depth leaves clearance for wiring gutters in a 200 mm deep enclosure. Maximum power loss is 19.7 W. That figure drives the thermal rise inside the panel; if you're packing multiple breakers in a sealed cabinet, factor it into the ventilation or forced-air calculation.
Operating environment and storage
Rated for operation from -25 °C to 70 °C ambient. Storage range is -40 °C to 80 °C — that wider storage window covers unheated warehouses and shipping containers. The trip indicator is not fitted on this variant; undervoltage release is also absent.
