What this MCCB delivers
The Siemens 3VA2216-7MN32-0AD0 is a SENTRON molded case circuit breaker (MCCB) rated for 160 A continuous current, built around the ETU350M electronic trip unit. It is a motor-protection version with phase-failure detection built in, so it catches the unbalanced load condition that cooks windings before the thermal curve would trip. Three auxiliary switches (HQ type) are integrated for remote status feedback — no separate add-on block needed for basic signaling. Breaking capacity is 330 kA at 240 V and 242 kA at 415/440 V, tapering to 187 kA at 500 V and 52.5 kA at 690 V. That 330 kA figure at 240 V is the headline — it safely interrupts faults up to that level without cascading upstream, which matters for high-fault installations like transformer secondaries or large motor control centers.
Thermal derating and panel fit
The 160 A rating holds flat from 40 °C through 50 °C ambient. Above that it derates stepwise: 153.6 A at 55 °C, 150.4 A at 60 °C, 147.2 A at 65 °C, and 144 A at 70 °C. If the panel ambient runs above 50 °C, size the downstream load against the derated value, not the nameplate 160 A. Maximum power loss is 75 W — that heat has to leave the enclosure, so factor it into the thermal budget. Footprint is 105 mm wide, 181 mm tall, 86 mm deep. That 105 mm width is a standard 3-pole MCCB frame — it drops into the same panel cutout as other 160 A SENTRON breakers. Operating range is -25 °C to 70 °C; storage range is -40 °C to 80 °C, which is the handling limit, not the running limit.
Lifecycle and sourcing posture
The part carries no undervoltage release, no voltage trigger, and no ground-fault monitoring — it is a straight overcurrent-protection device with phase-failure detection. If your application needs undervoltage or ground-fault protection, that requires a different variant or an add-on module.
