The Siemens SENTRON 3VA2216-5MN32-0DA0 is a 3-pole molded case circuit breaker (MCCB) rated for 160 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed until you cross that upper bound. That flat thermal curve simplifies panel sizing in warm enclosures or near motor starters. Its interrupting capacity hits 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. For a motor protection breaker, that SCCR headroom means it can sit upstream of a variable-frequency drive or across a high-fault utility feed without cascading coordination issues. No auxiliary switch is fitted; the UVR is the only auxiliary release on this variant.
The 86 mm depth includes the arc-chamber housing; verify clearance for the rear terminals and any auxiliary wiring trough. Maximum power loss is 22.2 W, which is moderate for a 160 A frame.
Environmental limits and storage
The storage limits exceed the operating range — that governs handling during transport and warehouse hold, not running conditions.
