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 frame 400 footprint matches other 3VA2 breakers in the same frame class, so busbar connections and handle mechanisms are common across the line.
