What it is — and what the ratings mean for fit
The 3VA2325-7MP32-0AA0 is a SENTRON 3VA2 molded case circuit breaker in the motor protection version, rated 250 A continuous with an ETU550M electronic trip unit. That 250 A holds flat from 40 °C through 70 °C — no derating curve to chase in a warm panel. Interrupting capacity hits 330 kA at 240 V, 242 kA at 415/440 V, 187 kA at 500 V, and 7.5 kA at 690 V. That's a fault-current rating that clears into high-capacity transformer secondaries or busway feeds without cascading upstream. Three poles, adjustable trip class, phase failure detection, and a communication function for remote monitoring. No undervoltage release or ground-fault monitoring.
Lifecycle and sourcing reality
Current-production status per Siemens — no phase-out notice, no last-time-buy window. Sourced and quoted to order through independent distribution; availability and current pricing confirmed at quote time against an RFQ. Mounts in a standard DIN-rail panel footprint: 138 mm wide, 248 mm tall, 110 mm deep. IP40 on the front — panel-side protection only; not rated for washdown or outdoor exposure.
What this MCCB is for
Motor protection MCCB for induction motor circuits where the ETU550M electronic trip provides adjustable overload class and phase-loss detection. Three-pole, 250 A frame — sized for a motor load up to that continuous rating, with the interrupting capacity to handle high-fault panel feeds.
