SENTRON 3VA2216-7MN32-0AJ0 — Motor Protection MCCB
The Siemens SENTRON 3VA2216-7MN32-0AJ0 is a 3-pole molded case circuit breaker (MCCB) designed specifically for motor protection, rated at 160 A continuously across the full ambient temperature range from 40 °C to 70 °C. Its interrupting capacity reaches 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 4.5 kA at 690 V — figures that give substantial SCCR headroom for most industrial distribution panels. The breaker includes phase failure detection and a trip indicator, and ships with a 2-auxiliary-switch plus 1-trip-alarm-switch HP configuration, so you get status feedback without adding external relays.
Sizing and Selectivity
The 160 A rating holds flat from 40 °C through 70 °C — no derating curve to calculate for warm enclosures. That simplifies coordination studies: the breaker delivers its full nameplate current even in a hot panel. Maximum power loss is 19.7 W, which matters for thermal management inside a sealed enclosure. Dimensions are 181 mm high, 105 mm wide, and 86 mm deep — a compact footprint for a 160 A frame, fitting standard SENTRON mounting patterns.
Integration Notes
Mounts on a standard DIN rail or panel-mount base in any SENTRON-compatible distribution board. The 3-pole form factor with auxiliary switch block occupies the same cutout as other 3VA2 frame breakers. Operating temperature range is -25 °C to 70 °C; storage from -40 °C to 80 °C. Suitable for unconditioned industrial environments.
