Siemens 3VA2216-5MN32-0AC0 — 160 A SENTRON MCCB for Motor Protection
Three poles, with phase failure detection integrated and two high-performance auxiliary switches (HQ type) for status feedback to the PLC or safety relay. Breaking capacity is the headline here: 187 kA at 240 V, 121 kA at 415 V and 440 V, dropping to 75.6 kA at 500 V, and 4.5 kA at 690 V. The 4.5 kA at 690 V is a reminder that at higher voltages the arc extinction is harder; this breaker is optimized for 400–480 V class systems, not 690 V main feeders.
