What this 3VA2 breaker is and what it does
The Siemens 3VA2325-7MS32-0AC0 is a 3-pole IEC molded-case circuit breaker from the 3VA2 series, using the frame 400 platform. It is sized for a 250 A continuous current (In) and carries a 110 kA interrupting capacity at 415 V AC — that is the Icu rating at the standard industrial distribution voltage, so it safely clears faults up to that level without upstream fuses or a larger frame needing to trip first. The ETU310M electronic trip unit provides adjustable short-circuit protection (Ii = 3…15 × In) but no overload protection — this is a starter-protection breaker, meaning it coordinates with a separate motor starter or contactor for overloads. The fixed instantaneous pickup range lets you dial in the magnetic trip to ride through motor inrush while still protecting the branch circuit.
Where it fits in the panel
This breaker mounts on a DIN rail or can be screw-fixed to a backplate in a standard distribution panel or motor control center. The frame 400 footprint matches other 3VA2 breakers in the same frame class, so busbar connections and handle mechanisms are common across the line. Two integrated auxiliary switch changeover contacts are built in — no separate accessory block needed for status feedback to a PLC or annunciator.
