The Siemens 3VA2340-0KP32-0AA0 is a 3-pole IEC molded case circuit breaker on a 400 A frame, rated for 200 kA breaking capacity at 415 V (breaking capacity class E). The ETU850 electronic trip unit provides LSI protection: long-time (Ir) adjustable 160-400 A, short-time (Isd) 0.6-10xIn, and instantaneous (Ii) 1.5-12xIn. This is a line-protection variant, so it's sized for feeder and main breaker duty, not motor branch-circuit protection.
RoHS compliant since October 2019. The IEC design means it's accepted across European, Middle Eastern, Asian, and African markets that follow IEC 60947-2. No UL listing is stated in the record, so for North American jobs verify site acceptance of the IEC rating.
Packaged dimensions 265 x 165 x 170 mm, single-piece quantity. Mounts in the standard MCCB panel footprint with screw-clamp terminals; no DIN-rail clip on this frame size.
