The Siemens 3VA2325-5MQ32-0AA0 is a SENTRON molded case circuit breaker (MCCB) built for motor protection duty — 3-pole, 250 A continuous rated, with a trip unit adjustable from 50 A to 250 A full-scale. Breaking capacity runs from 187 kA at 240 V down to 7.5 kA at 690 V — the 121 kA at 415 V and 440 V covers the common low-voltage industrial supply. That's enough SCCR headroom for most motor branch panels without cascading upstream breakers.
Motor protection specifics and communication
It also carries a communication function, meaning it can talk to a higher-level control system for status, trip events, and possibly remote reset — useful for a line where you want the breaker integrated into the SCADA or PLC alarm scheme rather than just sitting as a dumb overcurrent device.
No rewiring or panel rework needed if the original spec was a 3VA2-series 3-pole 250 A MCCB.
That covers unheated warehouses and outdoor-rated enclosures in most climates.
